Answer:

Step-by-step explanation:

A function

$a \times {b}^{x}$

where a is the initial value and b is the multiplicative rate of change.

In the function,

$f(x) = 2 \times {5}^{x}$

5 is the value of b so

5 is the multipicative rate of change

the solutions to the inequality y > −3x 2 are shaded on the graph. which point is a solution? a). (0, 2) b). (2, 0) c). (1, −

PolarNik [594]

we have

$y> -3x+2$

The solution is the shaded area above the dotted line

we know that

If a point is a solution of the inequality, then the coordinates of the point must satisfy the inequality

We will verify all cases to determine the solution of the problem

Case A) Point $(0,2)$

$x=0\\y=2$

Substitute the value of x and y in the inequality and verify

$2> -3*0+2$

$2>2$ -------> is not true

therefore

the point $(0,2)$ is not a solution of the inequality

Case B) Point $(2,0)$

$x=2\\y=0$

Substitute the value of x and y in the inequality and verify

$0> -3*2+2$

$0>-4$ -------> is true

therefore

the point $(2,0)$ is a solution of the inequality

Case C) Point $(1,-2)$

$x=1\\y=-2$

Substitute the value of x and y in the inequality and verify

$-2> -3*1+2$

$-2>-1$ -------> is not true

therefore

the point $(1,-2)$ is not a solution of the inequality

Case D) Point $(-2,1)$

$x=-2\\y=1$

Substitute the value of x and y in the inequality and verify

$1> -3*(-2)+2$

$1>8$ -------> is not true

therefore

the point $(-2,1)$ is not a solution of the inequality

therefore

the answer is the Point B

$(2,0)$

Mrs white wants to crochet beach hits and baby afghans for a church fund raising bazaar. she needs 7 hours to make a hat and 4 h

denis-greek [22]

This is a maximization problem so we apply derivatives here to determine the unknown variables in the problem.

In this problem, we represent x as the number of hats made, and y as the number of Afghans made by Mrs White.
Equation 1 relating to the time it takes to make these is expressed:

7x + 4y = 68
Another equation that represents inequality to the number of hats and Afghans respectively is expressed:
x<= 14
y<=11

the third equation expresses the income from selling these items expressed as
P = 21 x + 9y
we subtitute 1 to 3

P = 9(68-7x)/4 + 21x = 153-15.75x + 21 x = 153 -5.25x

So by trial and errror, x and y should be integers, we get two cases of which x and y should be

1) x = 4 ; y = 10
2) x = 8 ; y = 3

Subsituting to 3, P1 = 174$ while P2is equal to $195, Answer then is 8 hats and 3 Afghans in total.
