What is the shape of the graph of the function?
h(t) = 0.32 - 0.5t
Its pretty obvious since the other answer has 1 star, but its B. I got it right on khan academy:)
The correct statement is option A)
What are functions?Function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given here: The graph of the function h(t)=0.32-[tex]0.5^t[/tex]
which can be re written as h(t)= [tex]\frac{8}{25}[/tex] - [tex]\frac{1}{2} ^t[/tex]
Thus clearly as the value of t increases or as we move from negative to positive values the graph of the function tends towards zero and is negative for negative values of t.
For instance, at t= -4 we have
8/25 - 16=15.68
and at t=4 we have
8/25 - 1/16 =0.2575
And it intercepts the x-axis at (1.644,0)
Clearly h(t) is smaller for negative values of t and higher for higher values of t and thus has a upward curvature when we input the values from left to right.
Hence, The curve should slowly bend towards x-axis and option A is the correct answer because the graph is higher values for higher values of t.

Solve the system of linear equations by adding or subtracting.
3x + 7y = −17
4x − 7y = 10
Enter your answer as an ordered pair.
Answer:
3x + 7y = −17
4x − 7y = 10
Add up both sides of 2 equations, then
7x = -7
=> x = 1
=> y =(3 x 1 - 17)/7 = -14/7 = -2

XYZ Software employed three different salespeople last year. Person 1
earned $3900 in the first quarter, Person 2 earned $20,100 in the first quarter,
and Person 3 earned $6900 in the first quarter. What are the maximum FUTA
deductions for the first quarter?
Answer:
Total FUTA : $669.6
Step-by-step explanation:
Given the information
Person 1 earned $3900 in the first quarter Person 2 earned $20100 in the first quarter Person 3 earned $6900 in the first quarterAs we know, FUTA is short for Federal Unemployment Tax Act, and the FUTA tax rate is 6.2% applied to a maximum cumulative earnings of $7,000.
So in this situation, only person 1 and 2 must pay FUTA tax because ther earning are lower than $7,000.
Person 1: 3900 x 6.2% = $241.8Person 3: 6,900 x 6.2% = $427.8=> Total FUTA : $669.6

Answer:
A=14
Use formula A^2+B^2=C^2
Answer:
∠ A ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{MR}{AR}[/tex] = [tex]\frac{6}{15}[/tex] , thus
A = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 24° ( to the nearest degree )

when the input of the function is -4 what is the output of the function
Answer:
The output is 5
Step-by-step explanation:
-4 is the input (x value). To find the output, you have to find where -4 is on the line. -4 is on the line when 5 is the y coordinate (output).
Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)
y=
Answer:
y = -2x - 8
Step-by-step explanation:
We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.
We already know that the slope is -2, so that means m = -2.
We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.
Thus, our equation is: y = -2x - 8.

What are the solutions to the equation?
x2 + 6x = 40
Ox=-10 and x = 4
O x= -8 and x = 5
Ox= -5 and x = 8
x= -4 and x = 10
Answer:
A. x=4 and x= -10
Step-by-step explanation:
x^2 +6× = 40
x^2 +6x -40
(x-4)(x+10)
x-4 = 0
x+10 = 0
x= 4
x=-10
The solutions to the equation are x = -10 and x = 4.
Option A is the correct answer.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
To solve the equation x² + 6x = 40,
We need to first rearrange it into the standard quadratic form of:
ax² + bx + c = 0.
x² + 6x - 40 = 0
Now, we can factor the quadratic expression or use the quadratic formula to solve for x.
Factoring:
(x + 10)(x - 4) = 0
Setting each factor equal to zero and solving for x gives:
x + 10 = 0 or x - 4 = 0
x = -10 or x = 4
Therefore,
The solutions to the equation are x = -10 and x = 4.

Determine the values of the variables in isosceles trapezoid CHLE below.
Enter numbers only, do not enter units.
Answer:
The values of variables x and m are 11 and 17
Step-by-step explanation:
The question has missing details as the diagram of the trapezoid isn't attached.
(See attachment).
Given that trapezoid CHLE is isosceles then the angles at the base area equal (4x)
And
The angles at the top are also equal
8m = 11x + 15
At this point, the four angles in the trapezoid are 8m, 11x + 15, 4x and 4x..
The sum of interior= 360
So,
11x + 15 + 8m + 4x + 4x = 360
Collect like terms
11x + 4x + 4x + 8m = 360 - 15
19x + 8m = 345
Substitute 11x + 15 for 8m
19x + 11x + 15 = 345
30x + 15 = 345
30x = 345 - 15
30x = 330
Divide through by 30
30x/30 = 330/30
x = 11
Recall that 8m = 11x + 15;
8m = 11(11) + 15
8m = 121 + 15
8m = 136
Divide through by 8
8m/8 = 136/8
m = 17
Hence, the values of variables x and m are 11 and 17

A drawer has 9 pairs of white socks 7 pairs of black socks 6 pairs of brown socks and 3 pairs of blue socks you get dressed each morning in the dark in randomly reach into the sock drawer to get your socks after a day of wearing the socks you do not replace them until the weekend after you have done some laundry what is the probability that your sock selection goes in the following order for this week?
P(Black then white then white the brown then blue)=____
Answer:
0.0014 = 0.14%
Step-by-step explanation:
First we need to find the total number of pairs:
9 + 7 + 6 + 3 = 25 pairs
Then, we need to find the probability for each case:
First socks black: 7 pairs over 25: P1 = 7/25
Second socks white: 9 pairs over 24: P1 = 9/24 = 3/8
Third socks white: 8 pairs over 23: P1 = 8/23
Fourth socks brown: 6 pairs over 22: P1 = 6/22 = 3/11
Fifth socks blue: 3 pairs over 21: P1 = 3/21 = 1/7
The final probability will the the product of all probabilities above:
P = (7/25) * (3/8) * (8/23) * (3/11) * (1/7) = 0.0014 = 0.14%
Answer:
567/398475 in fraction or 0.0014229249 in decimal
Step-by-step explanation:
In the question, we are given these values
Total pair of socks = 25 pairs of socks
9 pairs of white socks
7 pairs of black socks
6 pairs of brown socks
3 pairs of blue socks
From the question, we can see that, this is probability without replacement.
Hence,
P(Black then white then white the brown then blue)=
7/25 × 9/24× 8/23 ×6/22 × 3/21
= 9072/6375600
= 567/398475
Therefore, the Probability of picking a Black socks then white socks then white socks , then brown socks and then blue socks = 567/398475 in fraction or 0.0014229249 in decimal

Mr. Morris asked Rob to shovel the snow from his driveway every day that it snowed during the month of January. He agreed to pay Rob $0.01 for the first day, $0.02 for the second day, $0.04 for the third day, $0.08 for the fourth day, and so on. If it snowed for 13 days in January, how much would Mr. Morris pay Rob on the 13th day?
Do not answer if you do not know. Only good answers with explanations.
Answer:
Total amount to be paid on 13th day is $40.96.
Step-by-step explanation:
Mr. Morris pays Rob $0.01, $0.02, $0.04 ..... on 1st, 2nd , 3rd .... day respectively.
We can clearly see that the next number is becoming double of the previous value.
The above sequence of numbers are in a Geometric Progression with
First term, a = 0.01 and
Common ratio, r = 2
We have to find the total amount paid on 13th day.
We know that the [tex]n^{th}[/tex] term of a GP is given by:
[tex]a_{n} =ar^{n-1}[/tex]
Where, a is the first term of GP
r is the common ratio
We have to find the [tex]13^{th}[/tex] term of the GP as per question statement.
Putting the values in the formula above:
n = 13
a = 0.01 and
r = 2
[tex]a_{13} = 0.01 \times 2^{13-1}\\\Rightarrow 0.01 \times 2^{12} \\\Rightarrow 0.01 \times 4096\\\Rightarrow 40.96[/tex]
Total amount to be paid on 13th day is $40.96.
