Answer: a) 15625, b) 0.2, c) 625, d) 0.008.

Step-by-step explanation:

Since we have given that

a) $(5^2)(5^3)$

As we know that

$a^m\times a^n=a^{m+n}$

So, it becomes,

$5^2\times 5^3=5^{2+3}=5^6=15625$

(b) $(5^2)(5^{-3})$

So, it becomes,

$5^2\times 5^{-3}=5^{2-3}=5^{-1}=\dfrac{1}{5}=0.2$

As we know that

$(a^m)^n=a^{mn}$

So, it becomes,

$5^{2\times 2}=5^4=625$

(d) $5^{-3}$

$a^{-m}=\dfrac{1}{a^m}\\\\5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}=0.008$

Hence, a) 15625, b) 0.2, c) 625, d) 0.008.

For a house call, a veterinarian charges $70, plus $40 an hour. A. Write an equation that represents the total fee y y (in dolla

Elodia [21]

Answer:

Let x represents the hours and y represents the total fees(in dollars)

As per the statement:

(a)

For a house call, a veterinarian charges $70, plus $40 an hour

"$40 an hour" means 40x

then;

the equation we get;

$y = 40x + 70$ .....[1]

(b).

Find the x-intercept.

x-intercept states that the graph cross the x-axis.

Substitute y = 0 in the equation and solve for x;

we get;

$x = -\frac{7}{4}$

y-intercept states that the graph crosses the y-axis i.e

Substitute x= 0 in the equation and solve for y;

$y =70$

Therefore, x-intercept and y-intercept of equation [1] are:

$-\frac{7}{4}$ and 70
