This is an exponential expression with 10 as the base and 4 as the exponent.

=============================================

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand

Answer:

33

Step-by-step explanation:

f(4) = 4(4) - 3 = 16 - 3  =  13

g(-5) = -2(-5) + 10  =  10 + 10  =  20

13 + 20 = 33

Explanation:

Recall that the general point-slope form is [tex]y - y_1 = m(x - x_1)[/tex] where m is the slope and [tex](x_1, y_1)[/tex] is the point the line goes through. We see that the 2 and the m match up, so m = 2 is the slope.

Side note: We can rewrite that given equation into y - (-5) = 2(x - (-1)) to see that the line goes through the point (-1, -5)

Answer:

C: 2

Step-by-step explanation:

y + 5 = 2x + 2 (distribute 2)

y = 2x -3 (subtract 5 from both sides)

2x means: slope times x

Answer:

Since from the laws of exponents we have that x−n=1xn , it implies that we may write 18=8−1 . 18=123=2−3.

Step-by-step explanation:

p(x) = 90 / (9 + 50 * e^(-x))

e = 2.718, so we can use e = 2.7 as a quick substitute

p(3) =>

90 / (9 + 50 * e^(-3)) =>

90 / (9 + 50 * 2.7^(-3)) =>

90 / (9 + 50 / 2.7^3) =>

90 / ((9 * 2.7^3 + 50) / 2.7^3) =>

90 * 2.7^3 / (9 * 2.7^3 + 50)

2.7^3 =>

(27/10)^3 =>

27^3 / 1000 =>

729 * 27 / 1000 =>

2187 * 9 / 1000 =>

6561 * 3 / 1000 =>

19683 / 1000 =>

19.683

90 * 2.7^3 / (9 * 2.7^3 + 50) =>

90 * 19.683 / (9 * 19.683 + 50)

9 * 19.683 =>

9 * (20 - 0.317) =>

180 - 9 * 0.317 =>

180 - 9 * 0.3 - 9 * 0.017 =>

180 - 2.7 - 9 * 0.01 - 9 * 0.007 =>

177.3 - 0.09 - 0.063 =>

177.3 - 0.153 =>

177.15 - 0.003 =>

177.147

90 * 19.683 / (9 * 19.683 + 50) =>

10 * 177.147 / (177.147 + 50) =>

1771.47 / 227.147 =>

1771470 / 227147 =>

1770000 / 225000 =>

1770/225 =>

Answer:

x^2+9x+8

Step-by-step explanation:

Expand the following:

(x + 1) (x + 8)

(x + 1) (x + 8) = (x) (x) + (x) (8) + (1) (x) + (1) (8):

x x + 8 x + x + 8

x x = x^2:

x^2 + 8 x + x + 8

Grouping like terms, x^2 + 8 x + x + 8 = x^2 + (8 x + x) + 8:

x^2 + (8 x + x) + 8

8 x + x = 9 x:

Answer: |

| x^2 + 9 x + 8

Answer:

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

Step-by-step explanation:

Let the width of the rectangular blanket be given by w and the length be given by l. According to the given condition length = 10+ width

Area of the rectangular blanket= length * width

A= l*w    ( as l= w+10)

A = (w+10) w

A= w²+ 10w

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

It can be written as

f(w) =  (w+10) w.

The function f(w) = w²+ 10w gives the area of the rectangular blanket.

The area of the rectangle is the product of the length and width of a rectangle.

Area of rectangle = L × W

Let the width of the rectangular blanket be given as w and the length be given by l.

The length is given as 10 inches greater than its width

length = 10+ width

Area of the rectangular blanket= length × width

A= l × w    

also, A = (w+10) w

A= w²+ 10w

Therefore, the function f(w) = w²+ 10w gives the area of the rectangular blanket.
