I hope this helps you

f (x)=(x+8)^3. (x-3)

x+8=0 x= -8

x-3=0 x=3

When a zero repeats, it has a multiplicity of how many times it repeats
we see that (x+8) repeats 3 timess
set them to zero

x+8=0
x=-8

x-3=0
x=3

roots are -8 and 3

-8 has a multilicty of 3

so
roots are 3 and -8 multiplicty 3

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331.

deff fn [24]

Option D

The regression line predicts that at x = 4, y equals 2143

<em><u>Solution:</u></em>

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

$\text{ log } y = 3.331$

We need to find the value of 'y' when x = 4

$log_{10}y = 3.331$

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

$10^{log_{10}y} = 10^{3.331}\\\\\text{10 power log base 10 cancels, we get }\\\\y = 10^{3.331}\\\\y = 2142.89$

On rounding to nearest whole number, we get 2143

Thus Option D is correct

Johns dog weighed 7pounds when he got him the dogs weight tripled each year for two years how many ounces does johns dog now wei

Delvig [45]

First gotten dog (starting weight)- 7 pounds
First year- 7 pounds times three, because the dog's weight triples each year, which equals 21 pounds.
Second year- 21 pounds times three equals 63 pounds.

Now, we need to convert the 63 pounds into ounces, which would be 1,008 ounces.
