What are the zeros of the function? f(t)=t2−13t 36 Enter your answers in the boxes. And.
Answer:
t = 4, 9
Step-by-step explanation:
Hi there!
f(t) = t² - 13t + 36
Let f(t) = 0:
0 = t² - 13t + 36
Factor the equation:
0 = t² - 4t - 9t + 36
0 = t(t - 4) - 9(t - 4)
0 = (t - 9)(t - 4)
The zero-product property states that if the product of two numbers is zero, then one of the numbers is equal to zero. Therefore, either (t - 9) or (t - 4) is equal to zero:
t - 9 = 0
t = 9
t - 4 = 0
t = 4
Therefore, the zeros of the function are 4 and 9.
I hope this helps!

Answer:
Angle BCD = 25 degrees, angle ABC = 94 degrees, angle ACB = 43 degrees
Step-by-step explanation:
This is an Isosceles triangle, so Angle BCD = 180 - 22 - 133 = 25 degrees.
Angle ABC = 360 - 133 - 133 = 94 degrees.
Angle ACB = (180 - 94)/2 = 43.

10. What is the solution of the system of equations below?*
y=-3x
x+y=4
Answer:
x = -2
y = 6
Step-by-step explanation:
y = -3x
x + y = 4
the substitution method works nicely here because the first equation is already solved for 'y'
so we can substitute '-3x' for 'y' in the second equation:
x + (-3x) = 4
-2x = 4
x = -4/2
x = -2
now we can solve for y:
y = -3(-2)
y = 6

Mr. McKay wrote an algebra test with a total of 15 questions consisting of multiple choice and short response style questions. Multiple choice questions, x, were worth 5 points each and short response questions, y, were worth 10 points each. There were 100 total possible points on the test. Write and graph a system of linear equations for this situation to determine the number of each type of question.
Step-by-step explanation:
x = number of multiple choice questions
y = number of short response questions
x + y = 15
5x + 10y = 100
=>
x + 2y = 20
let's subtract the first from the second equation :
x + 2y = 20
- x + y = 15
--------------------
0 y = 5
x + y = 15
x + 5 = 15
x = 10
to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b
a is the slope, b is the y- intercept.
x + y = 15
transforms to
y = -x + 15
this line goes e.g. through the points (0, 15) and (1, 14).
and
x + 2y = 20
transforms to
2y = -x + 20
y = -x/2 + 10
this line goes e.g through (0, 10) and (2, 9).
the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.

Y=3x-8
Y=4x-8

sandy works at a clothing store. she makes $9 per hour plus earns a 15% commission on her sales. she worked 77 hours over the last two weeks and had a total of $ 2,226 in sales before tax .
which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
a. $438
b. $1,027
c. $693
d. $334
Answer:
B. $1,027
Step-by-step explanation:
9 x 77 =
693
2,226 - 15% =
1,892
2,226 - 1,892 =
334
693 + 334 =
1,027
Sandy made $1,027 in the past two weeks including commission

In a laboratory experiment, the population of bacteria in a petri dish started off at 160 and is growing exponentially at 6% per hour. Write a function to represent the population of bacteria after t hours, where the rate of change per minute can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per minute, to the nearest hundredth of a percent.
The exponential function is given by y = 160(1.06)ˣ
Exponential function
An exponential function is in the form:
y = abˣ
where a is the initial value of y, b is the multiplier, y, x are variables.
Let y represent the amount of bacteria after x hours.
Given an initial 160 bacteria, hence a = 160.
Also b = 100% + 6% = 106% = 1.06
The exponential function is given by y = 160(1.06)ˣ

Since both equations have the same slope, but different y-intercepts, both equations are parallel from each other, therefore there's no intersection between both of the graphed lines.
No intersection means absolutely no solutions.

Reflect shape A in the line y=x.
FAST PLEASE!!!
Answer:
see attached diagram
Step-by-step explanation:
To reflect a point in the line y = x, then all you need to do is swap the x and y coordinates (as y = x!)
So the point (1, -2) becomes (-2, 1)
(4, -2) becomes (-2, 4)
and so on.
