Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

$\bf \textit{Logarithm Cancellation Rules}\\\\
log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\
-------------------------------\\\\
10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2)
\\\\\\
3+2\implies 5$

What are the solutions to the equation 3(x – 4)(x + 5) = 0

Ne4ueva [31]

Answer:

x=4

x=-5

Step-by-step explanation:

in order for this to be equal to 0, 1 or both of the factors has to be 0, because anything multiplied by 0 is 0.

123 * 29382 * 8139* 0 = 0

x-4 = 0

x = 4

x+5 = 0

x=-5

How many more calories do you burn per minute downhill skiing than hiking

FrozenT [24]

Answer: 2 more calories skiing

Step-by-step explanation:

First find the slope of each line.

Slope of Skiing:

= (Y₂ - Y₁) / (X₂ - X₁)

= (400 - 240) / (50 - 30)

= 8

= 8 calories per minute

Slope of Hiking

= (360 - 120) / (60 - 20)

= 6

= 6 calories per minute

Difference:

= 8 - 6

= 2 more calories skiing

What is the product (9t-4)(-9-4)

Scrat [10]

Answer:

-81t^2 +16

Step-by-step explanation:

(9t-4)(-9t-4)

FOIL

first: -9t*9t = -81t^2

outer : -4*9t = -36t

inner : -4 *-9t = 46t

last = -4*-4 = 16

Add them together

-81t^2 -36t+36t+16

-81t^2 +16

Determine the value of f(2) that will lead to an average rate of change of 15 over the interval [2,6]. (HELP PLEASE)

Fofino [41]

Average Rate of Change/Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:

$\frac{71-y}{6-2}=15$

From here we can solve for y. Firstly, solve the subtraction:

$\frac{71-y}{4}=15$

Next, multiply both sides by 4:

$71-y=60$

Next, subtact both sides by 71:

$-y=-11$

Lastly, multiply both sides by -1, and <u>your final answer will be $y=11$ , or A.</u>
