Does this table represent an exponential function? x 1 2 3 4 y 4 16 64 256
4vir4ik [10]

Answer:

Yes, the given table represent an exponential function.

Step-by-step explanation:

Given table is :

x y

1 4

2 16

3 64

4 256

Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function y=ab^x.

We see that y-values are basically powers of 4 so we can write the related function as y=4^x.

Which is clearly in form of y=ab^x.

Hence yes, the given table represent an exponential function.

Calculate the length of the altitude (h) of the rhombus
allochka39001 [22]

Answer:

h = 15

Step-by-step explanation:

Use Pythagorean Theorem to solve for h.

a² + b² = c²

8² + h² = 17²

64 + h² = 289

h² = 225

h = 15

How to do this and how to find the numbers for it?
hodyreva [135]
So I have the formula for the reflection over the x-axis is from (x,y) to (x,-y), and the reflection for the y-axis is (-x,y). Next, I have the original for A(2,-2), B(2,-6), and (9,-6) which is reflection over x-axis which is A(2,2), B(2,6), and C(9,6). Then, I have A(-2,-2), B(-2,-6), and C(-9,-6) for the reflection over the y-axis. Hope it help!

A gardener can care for the Green's property in 5 hours. If his helper assists him, they can complete the job in 4 hours. How lo
PilotLPTM [1.2K]

Step-by-step explanation:

Fraction of work done by Gardner in 1 hr = 1 / 5

Fraction of work done by Gardner and helper in 1 hr = 1 / 4

Fraction of work done by helper in 1 hr

= 1 / 4 - 1 / 5

= 1 / 20

<u>Time required by helper to complete work</u> :

= <u>20 hours</u>

Find the value of x. Round the answer to the nearest tenth, if needed.
zepelin [54]

Answer:

D

Step-by-step explanation:

The diagram is composed of one large right triangle and inside it it's divided into 2 small right triangles. Since these triangles all have the same shape but not the same size, they are similar triangles. Using similar triangles, create a proportion of side lengths. A proportion is an equation with equal ratios from the large triangle to a small. Notice the large triangle has a hypotenuse of 6+7 = 13 and a leg of x. The small triangle has a hypotenuse of x and a leg of 7.

\frac{hypotenuse}{leg}=\frac{hypotenuse}{leg}

\frac{13}{x}=\frac{x}{7}

To solve for x, cross multiply the numerator with the denominator.

x*x = 13*7\\x^2 = 91\\x=\sqrt{91} \\x=9.5
