Answer:

$27 approx

Step-by-step explanation:

Given data

Membership fee= 14.99 per month

for a year the fee is 14.99*12= 179.88

discount = 15%

=15/100*179.88

=0.15*179.88

=26.982

Hence for a year, you will save $27 approx

Answer:

The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].

Step-by-step explanation:

Let [tex]3\cdot x^{2}+x - 3 = 0[/tex], the quickest and most efficient approach to find the zeroes of this second order polynomial is by Quadratic Formula. For all [tex]a\cdot x^{2}+b\cdot x + c = 0[/tex], roots are determined by:

[tex]x_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex] (1)

Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are coefficients of the polynomial.

If we know that [tex]a = 3[/tex], [tex]b = 1[/tex] and [tex]c = -3[/tex], then roots of the polynomial are, respectively:

[tex]x_{1,2} = \frac{-1\pm\sqrt{1^{2}-4\cdot (3)\cdot (-3)}}{2\cdot (3)}[/tex]

[tex]x_{1,2} =\frac{-1\pm \sqrt{37}}{6}[/tex]

The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].

Answer:

Step-by-step explanation:

first we add them altogether:

0.25+0.17+0.21+0.03 = 0.66

than we subtact the 0.66 from the whole (1) =

1-0.66= 0.34

Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.

Step-by-step explanation:

The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:

Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.

And there's your answer.

Answer:

y=16x+9

Step-by-step explanation:

y-y1=m(x-x1)

y-9=16(x-0)

y-9=16(x)

y-9=16x

y=16x+9

*Complete Question:

A and B are two similar cylindrical containers.

Surface area of container A: surface area of container B = 4:25

Warda fills container A with oil.

She then pours all the oil into container B.

Warda repeats this and stops when container B is full of oil.

Work out the number of times that Warda fills container A with oil.

Answer/Step-by-step explanation:

We are given that the ratio of surface area of cylinder A to cylinder B = 4:25

To find out the number of times Warda fills cylinder A with oil, we need to find the ratio of the volume of cylinder A to cylinder B.

✔️First, find the linear measurement using the ratio of their surface area by taking their square root:

4:25 = √4/√25 = 2/5

Linear measurement of A to B = 2:5

The ratio of their volume = the cube of the ratio of their linear measurement

Thus, the ratio of the volume of A to B = 2³:5³ = 8:125

For Cylinder B to be filled, it would require 125/8 = 15.625 of cylinder A filled with oil. That means Warda would have to fill Cylinder A with oil for approximately 15 times, then an extra fraction of cylinder A to completely fill cylinder B with oil.

Answer:

False

Step-by-step explanation:

Answer:

x = 3 and y = 5

Step-by-step explanation:

Given equations are :

y=5x−10 ..(1)

y=−3x+14 ...(2)

Subtract equation (2) from (1).

y-y = 5x−10-(−3x+14)

0 = 5x-10+3x-14

0= 8x-24

8x = 24

x = 3

Put the value of x in equation (1).

y=5(3)−10

= 15-10

y = 5

So, the values of x and y are 3 and 5 respectively.

Answer:

765.437 grams

Step-by-step explanation:

as 1 ounce =28.35g

so

27ounce=28.35×27

=765.437

Converting 27 ounces into grams is: 765.437grams.

Here, we have,

given that,

we have to Convert 27 ounces into grams.

we know that,

Since 1 ounce is equal to 28.35 grams.

so, we get,

1 ounce=28.35 grams

all we need to do is to multiply 27 by 28.35 grams.

i.e. 28.35×27 =765.437

The answer will be 765.437grams.

so, we get,

as 1 ounce =28.35g

so, 27ounce=28.35×27 =765.437g

Answer:

9.7%

Step-by-step explanation:

Given data

Expected value= 277

Actual value= 250

%Error= Actual- Expected/Expected *100

%Error= 250-277/277 *100

%Error= 27/277 *100

%Error= 0.097*100

%Error= 9.7

Hence the error is 9.7%

Answer:

85 inches

Step-by-step explanation:

Using pythag.  A^2 + B^2 = C^2  

(68*68) + (51*51) = 7225^2

Thus if you square root 7225, you get your answer - 85 inches.

Answer:

the factorised form is 4(8a+9)

Answer:

Both are true.

Step-by-step explanation:

If f(x) = 2x³ + 6

To find the inverse of the given function,

Rewrite the function in the form of an equation,

y = 2x³ + 6

Interchange the variables x and y,

x = 2y³ + 6

Solve for y,

2y³ = x - 6

y = [tex]\sqrt[3]{\frac{(x-6)}{2}}[/tex]

Rewrite the equation in the form of a function,

[tex]f^{-1}(x)={\sqrt[3]{\frac{(x-6)}{2}}[/tex]

[tex](fof^{-1})(x)=f[f^{-1}(x)][/tex]

                  = [tex]2(\sqrt[3]{\frac{(x-6)}{2}})^3+6[/tex]

                  = (x - 6) + 6

                  = x

[tex](f^{-1}of)(x)=f^{-1}[{f(x)][/tex]

                  [tex]={\sqrt[3]{\frac{(2x^3+6-6)}{2}}[/tex]

                  [tex]={\sqrt[3]{\frac{(2x^3)}{2}}[/tex]

                  = x

Therefore, both the statements are true.
