Answer:

3 points

Step-by-step explanation:

3 is very different from the other numbers, so it is an outlier.

Answer:

3 points (Clearly because if you put it on a number line, this one would be far away from the other numbers)

Answer:

I believe the third option is correct!

Answer:

$23.22 per day.

Step-by-step explanation:

For a general function f(x), the average rate of change between A and B (when B > A) is:

[tex]r = \frac{f(B) - f(A)}{B - A}[/tex]

In this case we know that the function is:

f(x) = 0.01*(2)^x

And we want to find the average rate of change from day 7 to day 14

Then if we use the above equation we get that the rate of change from day 7 to day 14 is:

[tex]r = \frac{0.01*(2)^{14} - 0.01*(2)^7}{14 - 7} = 23.22[/tex]

Because this equation is in dollars, we can conclude that the average rate of change between day 7 and day 14 is $23.22 per day.

An average rate of change between A and B (where B>A) for a generic function [tex]f(x)[/tex] is:

[tex]\to r=\frac{f(B)-f(A)}{B-A}\\\\[/tex]

[tex]\to f(x) = 0.01\times (2)^x[/tex]

[tex]\to r=\frac{0.01\times 2^{14} -0.01 \times 2^7}{14-7}=23.22[/tex]

Since this equation is stated in dollars, we can calculate that the average rate of change between days 7 and 14 is [tex]\$23.22[/tex] each day.

Answer:

20, 45

Step-by-step explanation:

A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles  must add up to 65.

The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9

A ratio partition parts of something. We can add the ratio intergers to find it full length.

4+9=13.

Divide 65/13=5.

Multiply 5x4 and 5x9 serpately.

We get 20 and 45

The expression that represents the change Mrs. Smith got back is 50 - x dollars.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A pet store is having a pet fish sale.

let, the cost of the Koi fish is 'x' dollars.

Therefore, With a $50 bill change(C) Mrs. Smith got back is represented by the expression,

C = (50 - x) dollars.

So, The change Mrs. Smith got back is 50 - x dollars.

Answer: -5

Step-by-step explanation:

The value of negative zero in g(x) = 3x² + 14x - 5 is 1.

Descarte's rule for no. of at most positive real roots in a polynomial is the no. of sign changes in the polynomial.

Descarte's rule for no. of at most negative real roots in a polynomial f(x) is the number of sign changes in f(-x).

All the other left over roots are imaginary and come in conjugate pairs.

The number of negative of f is equal to the number of sign changes of successive terms of f(-x).

Given, g(x) = 3x² + 14x - 5.

Now, g(-x) = 3(-x)² + 14(-x) - 5.

g(-x) = 3x² - 14x - 5.

The signs are +, -, - so only one sign changes.

Answer:

[tex]Area = 4h^2-56h +144[/tex]

Step-by-step explanation:

Given

See attachment for complete question

Required: The base area.

From the question, we have the initial dimensions to be:

[tex]Length = 12[/tex]

[tex]Width = 12[/tex]

h inch were removed from each corner to form the new base. So, the dimension of the new base is:

[tex]Base\ Length = Length - h - h[/tex]

[tex]Base\ Length = Length - 2h[/tex]

[tex]Base\ Width = Width - h-h[/tex]

[tex]Base\ Width = Width - 2h[/tex]

The area of the base is calculated by multiplying the base dimensions

[tex]Area = Base\ Length * Base\ Width[/tex]

[tex]Area = [Length - 2h] * [Width - 2h][/tex]

[tex]Area = [12 - 2h] * [12 - 2h][/tex]

Expand

[tex]Area = 12[12 - 2h] -2h [12 - 2h][/tex]

[tex]Area = 144 - 28h -28h + 4h^2[/tex]

[tex]Area = 144 -56h + 4h^2[/tex]

Rewrite as:

[tex]Area = 4h^2-56h +144[/tex]

Solution :

Given :

[tex]$f(x)=x^3-x^2-18x+19$[/tex]

By using the remainder theorem, if f(x) is divided by (x-k) and the remainder is 'r', then

[tex]$f(x)=(x-k)q(x)+r$[/tex]

Here, k = 4

Therefore, divide the f(x) with (x - 4) to find the q(x) and r.

Answer:

if you use the 10 feet ladder base is 6 feet

if you use 12 feet ladder base is 8.94 feet

if you use 15 feet ladder base is 12.69 feet

Step-by-step explanation:

you know the ladder length so you know the hypotenuse

you can use a^2 + b^2= c^2

for example you use the 10 feet ladder

8^2+b^2 = 10^2

64 + b^2 = 100

subtract 64 from both sides

b^2=36

to get rid of the exponent find square root

b= 6

you can plug in the different values like 15 or 12

Answer:

9.2 %

Step-by-step explanation:

Given: 0 on finals, overall is 90.8, then 0.01%

To find: How much of Kyle’s grade dropped

Solve: First, calculate the percentage you received on the test by dividing your mark by the total marks.

Kyle scored 0 out of 100, then 0/100 = 0 percent.

Secondly, multiply your percentage score on the test by the percentage it is worth of the final grade.

0 × 90.8 = 9.2 %  

9.2 %  of the final grade
