Answer:

Step-by-step explanation:

( x + 5 )² - 64 = 0

( x + 5 )² = 64

x + 5 = ± √64

x + 5 = ± 8

(1). x + 5 = - 8

x = - 13 ( lesser )

(2). x + 5 = 8

x = 3 ( greater )

Answer:

a=10

Step-by-step explanation:

Step 1: Add 54 to both sides.

9a−54+54=36+54

9a=90

Step 2: Divide both sides by 9.

9a\9 =90\9

a=10

Answer:

a=10

Step-by-step explanation:

Add 54 to both sides. You get 9a=90. Divide both sides by 9 and you get a=10.

Answer:

8750

Explanation:

There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.

3500=2/5

divide 3500 by 2 to get 1/5 of the math teachers.

3550/2=1750

1750 is 1/5 of the math teachers.

multiply 1750 by 5 to get 5/5 of the math teachers

1750*5= 8750

Answer:

Solve for x = 17

Solve for y = 9

The value of x and y from the figure are 17 and 7 respectively

From the given diagram, we are told that  I ll m, hence:

Get the value of x

5x-3x = -4 + 38

2x = 34

x = 34/2

x = 17

Also from the triangle:

7y - 20 + 5x - 38 = 90

7y + 5x -58 = 90

7y + 5(17) = 90 + 58

7y + 85= 148

7y = 148 - 85

7y = 63

y = 63/7

y = 9

Hence the value of x and y from the figure are 17 and 7 respectively

Answer:

Step-by-step explanation:

This is a list of trigonometric functions with the same maximum value:

(A) y = arcsinx and y = cos x

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.

They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.

There are six popular trigonometric functions for an angle.

Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

So, the following equations give us the following maximum values:

arcsinx = -1 to 1

arccosx = -1 to 1

arctanx = -pi/2 to pi/2

arcsecx = ∞

Arcsinx and Arccosx are trigonometric functions that have the same maximum value.

Therefore, this is a list of trigonometric functions with the same maximum value:

(A) y = arcsinx and y = cos x

Step-by-step explanation:

x = 6.5

Explanation:

[tex]\sf 23 - 2x = 10[/tex]

subtract 23 from both sides

[tex]\rightarrow \sf 23-2x-23=10-23[/tex]

simplify the following

[tex]\rightarrow \sf -2x=-13[/tex]

divide both sides by -2

[tex]\rightarrow \sf \dfrac{-2x}{-2}=\dfrac{-13}{-2}[/tex]

simplify

[tex]\rightarrow \sf x=\dfrac{13}{2}[/tex]

in decimals

[tex]\sf \rightarrow x = 6.5[/tex]

Recheck the following

[tex]\hookrightarrow \mathrm{23 - 2(6.5) = 10}[/tex]

[tex]\hookrightarrow \mathrm{23 -13 = 10}[/tex]

[tex]\hookrightarrow \mathrm{10 = 10}[/tex]

L.H.S = R.H.S thus. x = 6.5

Answer:

Apple Cider is the better deal.

Step-by-step explanation:

1 gallon is 128 ounces.

8 times 4.23 is 33.84. So each purchase is 33.84 ounces. If you multiply 33.84  ounces by 4 you get 135.36. (I did 4 because 3 would be too little to make a gallon).

After that you need to multiply 2.39 and 4. You need to do this because it will tell you the cost. That will come out to 9.56$.

So, that is why the apple cider is a better deal, because it is 7$ and the other would be 9.56$.

Answer:

15 ounces

Step-by-step explanation:

0.75 tons is equal to 0.75 * 2000, or 1500, pounds (1 ton is 2000 pounds). Let x represent the number of ounces of fertilizer that should be applied. Set up a proportion:

[tex] \ \frac{1}{100} = \frac{x}{1500} [/tex]

Solving this for x, we have x = 15. So the landscaper should apply 15 ounces of fertilizer.
