Answer:

Step-by-step explanation:

To find the y- intercept let x = 0

From the table for f(x)

When x = 0 → f(x) = - 4

That is the y- intercept = - 4

Given

g(x) = 3 $(2)^{x}$

let x = 0 , then

g(0) = 3 $(2)^{0}$ [ $2^{0}$ = 1 ]

= 3 × 1

= 3

That is the y- intercept = 3

Thus the y- intercept of g(x) is greater → B

Answer:

The required equation is $P(t) = -52t + 480$

Step-by-step explanation:

Consider the provided information.

Let P represent the number of pages left to read after t hours.

Shryia read a 480-page-long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read.

Total number of page Shryia read in 1.5 hours is:

480-402 = 78

It is given that the rate is constant i.e 1.5 hours,

Therefore, she read 78 pages in 1.5 hours.

She can read $\frac{78}{1.5} = 52$ page per hour

The required equation is:

$P(t) = -52t + 480$

Where t represents the number of hours.

Find the scale factor from Triangle ABC to Triangle DEF.

Kamila [148]

Answer:

The ratio of any two corresponding lengths in two similar geometric figures.

Step-by-step explanation:

You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.

If you divide the length of DE by the length of AB:

a^2/a =a.

You get a scale factor of “a”

3 over 8 by x Solve "x" A: 5 over 64 B: 5 over 9 C: 1 over 6 D: 3 over 4

lapo4ka [179]

Answer: 1 is correct

2 is correct

3 is correct

4 is correct

5 is correct

6 is correct

7 is correct

8 is wrong it should be because you wouldn't add you would subtract it and the other number is negative so it would be x=-26

9 is correct

10 is correct

13 is correct

14 I think is correct

I think 15 is incorrect because if he says one less than twice the number of last year then I think you first should subtract 1 from 25 and then divide by 2 this would give you 17 packages

and I think 16 is correct too.

Hope this helped

The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.

The area of a semi-circle is half the area of a full circle, so we can find it by using:

$A= \frac{1}{2} \pi r^2$

If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:

$A= \frac{1}{2} \pi (5)^2$

$A = 12.5 \pi$ or about 39.25

The area of a triangle is:

$A = \frac{1}{2} bh$

So we can plug in the known values to find the area to be:

$A= \frac{1}{2} (10)(12)=60$

When we add the areas of the two sections together, we get an exact answer of:

(60 + 12.5pi) cm^2

or about 99.25 cm^2
