Answer:
I think you wrote something wrong.
Step-by-step explanation:
If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.
for this example I'm giving Alaina 79 dollars.
First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.
For Joel our equation will be; y = 8x + 48.
Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.
They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.
Hope this helps!
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).

Suppose a polynomial of degree 4 with rational coefficients has the given numbers as zeros. Find the other zero.
Answer:
[tex]x_4 = -5 + i[/tex]
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]

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

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

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

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)

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.
