whats the scale factor from shape a to shape b
Answer:
scale factor = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
The scale factor is the ratio of corresponding sides , B to A
scale factor = [tex]\frac{50}{30}[/tex] = [tex]\frac{5}{3}[/tex]
Then
[tex]\frac{x}{15}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )
3x = 75 ( divide both sides by 3 )
x = 25
and
[tex]\frac{18}{y}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )
5y = 54 ( divide both sides by 5 )
y = 10.8
how do you know of an exponential fuction is reflected across the x-axis?
Answer:
Step-by-step explanation:
A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)
For example:
[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .
If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis
However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.
Hope this helps!

Answer:
132 units squared
Step-by-step explanation:
To start we can find the area of the rectangle, to do that we need to do
12*6=72
then we can find the area of the triangle, the formula to find a triangle's area of (b*h)/2, so we can do that
(10*12)/2=60
then we can add them together
72+60=132
Answer: 90
Step-by-step explanation:
Triangle=60
square=36
Now add them!
60+36=96

Answer:
perimeter = 16x+9x+8x+11
simplified perimter = 33x+11
Step-by-step explanation:
this isnt even close to 100 pts but okay
Answer:
a. 16x + 9x + 8x + 11
b. 33x + 11 (or 11(3x + 1) if this is asking for a factored expression)
Step-by-step explanation:
Looking at the directions, part a tells us to use all 4 side lengths, so the equation for part a is 16x + 9x + 8x + 11.
Now to simplify that expression.
16x + 9x + 8x + 11
Step: Combine 16x, 9x, and 8x. I'll go from left to right.
25x + 8x + 11
33x + 11
(What you see above this statement is my answer, but work is below if this is asking for a factored expression.)
11: 1, 11
33: 1, 3, 11, 33
Now divide both 33x and 11 by 11 and put the 11 outside the parentheses.
33x/11 = 3x
11/11 = 1
11(3x + 1)

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.
Answer:
(1165, 1235) (hours)
Step-by-step explanation:
The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:
(1200 - 35, 1200 + 35), or
(1165, 1235) (hours)
This is an application of the Empirical Rule.
The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).
What is the standard deviation?It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.
With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.
The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:
The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;
(1200 - 35)=1165
( 1200 + 35)=1235
(1165, 1235) (hours)
Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

Find the value of x. Write your answer in simplest form.
Answer:
x = 9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (9[tex]\sqrt{2}[/tex] )²
2x² = 162 ( divide both sides by 2 )
x² = 81 ( take the square root of both sides )
x = [tex]\sqrt{81}[/tex] = 9
Suppose a polynomial of degree 4 with rational coefficients has the given numbers as zeros. Find the other zero.

Step-by-step explanation:
See comment for complete question.
From the complete question, we have:
[tex]Zeros \to -2, -6, -5-i[/tex]
Required
Determine the other zero
The zeros can be represented as:
[tex]x_1 = -2[/tex]
[tex]x_2 = -6[/tex]
[tex]x_3 = -5-i[/tex]
Considering the 3rd zero, which is a complex number.
If a polynomial has a complex number as one of its zeros, then its conjugate pair is the corresponding zero
A conjugate pair is given as:
[tex]a + bi[/tex] and [tex]a - bi[/tex]
For [tex]x_3 = -5-i[/tex]
The conjugate pair is:
[tex]x_4 = -5 + i[/tex]
Hence, the other zero is: [tex]-5 + i[/tex]
