h(t)=-16t²+58t+2

h(2.5)

-16(2.5)²+58(2.5)+2
-16(6.25)+145+2
147-100
47ft

After 2.5s the ball was at 47ft

g(x)=x²-9

g(0)

-9

g(4)

4²-9=16-9=6

g(7)

7²-9
49-9
40

Range

{-9,6,40}

f(-3)=5
f(0)=0
f(1)=-3

How much is f(10) if f=x^2-2

dangina [55]

To find this value, simply substitute the number 10 in for x in your equation:

$f(x) = x^2 - 2$

$f(10) = 10^2 - 2 = \boxed{98}$

The answer is 98.

Answer:

(3.5, 17)

Step-by-step explanation:

It would be nice to see the whole graph, so we can see where the functions cross.

Without that information, we can still eliminate unreasonable choices.

A) the quadratic at y=3.5 is well above the exponential

B) the most likely choice (3.5, 17)

C) at x=-8, the quadratic is above the exponential

D) neither graph goes anywhere near y = -8

Answer:

The probability it will land on green every time is $\frac{1}{27}$ .

Step-by-step explanation:

We are given that a spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow.

The pointer is spun three times.

<u>As we know that the probability of an event is described as;</u>

Probability of an event = $\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}$

Here, the favorable outcome is that the spinner will land on green every time.

So, the number of green regions = 2

Total number of regions = 3(red) + 2(green) + 1(yellow) = 6 regions

<em>Now, the probability it will land on green every time is given by;</em>

Probability = $\frac{2}{6}\times \frac{2}{6}\times \frac{2}{6}$

= $\frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}$

= $\frac{1}{27}$

Hence, the probability it will land on green every time is $\frac{1}{27}$ .

Andrea spent a total of $43.87 on new clothes at a clothing store. She bought 1 pair of sandals for $8, 2 t-shirts for $9.49 eac

Misha Larkins [42]

43.87 - 8 = 35.87 (sandals)
9.49 + 9.49 = 18.98 ( for two t-shirts)
35.87 - 18.98 = 16.89 (t-shirts)
16.89 - 2.87 = 14.02 (taxes)
Andrea payed $14.02 for a pair of jeans
Hopes this helps you!
