For what values of x does 5x^2+4x-4= 0

Answers

The values of x that satisfy the equation are x = (-4 + 2√6) / 5 and x = (-4 - 2√6) / 5

What values of x satisfy the given equation?

The values of x that satisfy the equation 5x² + 4x - 4 = 0 can be determined using the quadratic formula given below:

x = (-b ± √(b² - 4ac)) / (2a)

From the equation:

a = 5, b = 4, and c = -4.

Substituting these values into the quadratic formula:

x = (-(4) ± √((4)² - 4(5)(-4))) / (2(5))

Simplifying to solve for values of x

x = (-4 ± √(16 + 80)) / 10

x = (-4 ± √96) / 10

x = (-4 ± 4√6) / 10

x = (-4 ± 2√6) / 5

Hence, x = (-4 + 2√6) / 5 or x = (-4 - 2√6)

A 3-D jigsaw puzzle becomes a cube with a volume of 1 cubic foot when it is solved. Mr. Ruiz stores several of these puzzles in a storage nook in his classroom. The nook is shaped like a rectangular prism and has a height of 3 feet. A layer of 8 puzzles will completely cover the floor of the nook. What is the volume of the storage nook?

Answers

The volume of the storage nook is 24 cubic feet.

How to find the volume of the storage nook

To find the area of 8 puzzles, we multiply the area of one puzzle by 8:

Area of 8 puzzles = 1 square foot * 8 = 8 square feet

Now, to find the volume of the storage nook, we multiply the area of the floor by its height:

Volume of the nook = Area of the floor * Height

= 8 square feet * 3 feet

= 24 cubic feet

Hence, the volume of the storage nook is 24 cubic feet.

To keep fish in an aquarium healthy, the aquarium must maintain an average water temperature of 67°F. For 14 hours of the day, no hearing is required as the aquarium is naturally at 69°F. However, if left unheated for the remaining hours the temperature would drop to 50°F. How many degrees (during heating hours) should the tank temperature increase to maintain the average temperature?​

Answers

Answer:

Step-by-step explanation:

To find out how many degrees the tank temperature should increase during the heating hours to maintain the average temperature, we need to calculate the temperature difference between the target average temperature of 67°F and the temperature during the unheated hours (50°F).

The difference in temperature is:

67°F - 50°F = 17°F

Since the heating hours account for the remaining hours of the day, which is 24 hours minus the 14 hours when no heating is required, we have:

24 hours - 14 hours = 10 hours

To maintain the average temperature of 67°F, the tank temperature should increase by 17°F during the 10 hours of heating.

To find the increase per hour, we divide the total temperature increase by the number of heating hours:

17°F / 10 hours = 1.7°F

Therefore, the tank temperature should increase by 1.7°F per hour during the heating hours to maintain the average temperature of 67°F.

What is a confidence interval of proportions?

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.

The margin of error is given as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

As we have no estimate, the parameter is given as follows:

[tex]\pi = 0.5[/tex]

Then the sample size for M = 0.04 is obtained as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 2.575\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.04\sqrt{n} = 2.575 \times 0.5[/tex]

For positive acute angles A and B, it is known that SinA= 11/61 and tan B=4/3. Find the value of Cos(A-B) in simplest form.

Answers

For positive acute angles A and B, if it is known that SinA= 11/61 and tan B=4/3, cos(A-B) = 224/305.

We can use the trigonometric identity cos(A-B) = cosA cosB + sinA sinB to find the value of cos(A-B).

First, we need to find the value of cosA and sinB:

Since sinA = opposite/hypotenuse, we can draw a right triangle with opposite side 11 and hypotenuse 61, and use the Pythagorean theorem to find the adjacent side:

cosA = adjacent/hypotenuse = √(61² - 11²)/61 = 60/61

Since tanB = opposite/adjacent, we can draw another right triangle with opposite side 4 and adjacent side 3, and use the Pythagorean theorem to find the hypotenuse:

hypotenuse = √(4² + 3²) = 5

sinB = opposite/hypotenuse = 4/5

Now we can substitute these values into the formula:

cos(A-B) = cosA cosB + sinA sinB

= (60/61)(3/5) + (11/61)(4/5)

= 180/305 + 44/305

The value of x in trapezoid KFGJ is 40.

Given information:

KFGJ is a trapezoid.

KF = 20

JG = x

MN is midsegment of trapezoid KFGJ.

MN = 30

To find the value of x in trapezoid KFGJ, we can use the fact that the midsegment MN of a trapezoid is parallel to the bases and its length is equal to the average of the lengths of the bases.

In this case, MN is given as 30, and we know that KF is one of the bases with a length of 20. To find the length of the other base JG, we can use the formula for the midsegment of a trapezoid:

MN = (KF + JG) / 2

Substituting the given values, we have:

30 = (20 + x) / 2

To solve for x, we can multiply both sides of the equation by 2:

60 = 20 + x

Subtracting 20 from both sides:

x = 60 - 20

x = 40

Therefore, the value of x in trapezoid KFGJ is 40.

Calculating the equations of the functions

Damari's investment

Given that

Initial value, a = 30000

B(3) = 32306.72

The function is calculated as

B(x) = a * bˣ

Using B(3), we have

30000 * b³ = 32306.72

So, we have

b³ = 1.077

Take the cube root of both sides

b = 1.03

So, we have

B(x) = 30000 * 1.03ˣ

So, the function is B(x) = 30000 * 1.03ˣ

Answers

Answers:

Choice A)  Segment AC = 2*sqrt(17)

Choice B)  Segment BD is 32 units long

Choice F)  Segment AB is approximately 33 units long.

==========================================================

Explanation:

The triangles are similar, so we can form this proportion

CD/DA = DA/BD

2/8 = 8/x

2x = 8*8

2x = 64

x = 64/2

x = 32

BD is 32 units long

This means one of the answers is choice B. It rules out choice D.

--------------

The legs of right triangle ABD are

AD = 8BD = 32

Use the pythagorean theorem to find hypotenuse AB.

a^2 + b^2 = c^2

(AD)^2 + (BD)^2 = (AB)^2

8^2 + 32^2 = (AB)^2

(AB)^2 = 64 + 1024

(AB)^2 = 1088

AB = sqrt(1088)

AB = sqrt(64*17)

AB = sqrt(64)*sqrt(17)

AB = 8*sqrt(17)

AB = 32.984845

Segment AB is approximately 33 units long.

This tells us another answer is choice F. Choice C is false because 4*sqrt(5) = 8.94427

--------------

BC = BD + DC

BC = 32 + 2

BC = 34

BC is the hypotenuse of triangle ABC

Use the pythagorean theorem to determine AC.

a^2 + b^2 = c^2

(AB)^2 + (AC)^2 = (BC)^2

(sqrt(1088))^2 + (AC)^2 = (34)^2

1088 + (AC)^2 = 1156

(AC)^2 = 1156 - 1088

(AC)^2 = 68

AC = sqrt(68)

AC = sqrt(4*17)

AC = sqrt(4)*sqrt(17)

AC = 2*sqrt(17)

Another answer is Choice A. It rules out choice E because 2*sqrt(17) = 8.2462 approximately.

The values of c  on the interval [-5, 5] are c = -[tex]5^{1/4[/tex]) and c = [tex]5^{1/4[/tex].

According to the Mean Value Theorem for Integrals, if f(x) is continuous on the interval [a, b], then there exists a value c in [a, b] such that:

f(c) = 1/(b-a) . ∫(a to b) f(x) dx

For f(x) = x⁴ on the interval [-5, 5], we have:

∫(-5 to 5) x⁴ dx = (1/5) . (5⁵ - (-5)⁵)/5

= (1/5) . (3125 + 3125)

= 1250

So we need to find c such that f(c) = 1250/10 = 125.

f'(x) = 4x³, so we can use the Mean Value Theorem for Derivatives to find a value of c that satisfies the condition.

f'(c) = (1/(5-(-5)))  . ∫(-5 to 5) f'(x) dx

= (1/10)  . [f(5) - f(-5)]

= (1/10) . [(5⁴) - ((-5)⁴)]

= 100

Therefore, by the Mean Value Theorem for Derivatives, there exists a value c in [-5, 5] such that f'(c) = 100.

Now, we need to check if there exists a value c in [-5, 5] such that f(c) = 125.

f(c) = c⁴, so we need to solve the equation c⁴ = 125.

c = ±[tex]5^{1/4[/tex]

Both of these values are in the interval [-5, 5], so they satisfy the Mean Value Theorem for Integrals.

Therefore, the values of c that satisfy the Mean Value Theorem for integrals for f(x) = x⁴ on the interval [-5, 5] are c = -[tex]5^{1/4[/tex]) and c = [tex]5^{1/4[/tex].

If  the sum of their ages 8 years ago was 48 then the present age​ of girl is 16 years.

Mrs. Sarfo is three times as old as her daughter, so her present age would be 3J years.

8 years ago, Joyce's age would have been J - 8, and Mrs. Sarfo's age would have been 3J - 8.

The sum of their ages 8 years ago was 48:

(J - 8) + (3J - 8) = 48

Simplifying the equation:

4J - 16 = 48

Adding 16 to both sides:

4J = 64

Dividing both sides by 4:

J = 16

Therefore, the present age of Joyce is 16 years.
