Identify the vertex of the following parabola.
y = x2 - 4x +1
Answer:
Step-by-step explanation:
Image result for Identify the vertex of the following parabola. y = x2 - 4x +1
To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.

Answer:
0.44
Step-by-step explanation:
See the picture below.
Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.
Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.
For angle J, leg LK is the opposite leg.
The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.
[tex]\sin J = \dfrac{opposite~leg}{hypotenuse}[/tex]
[tex] \sin J = \dfrac{39}{89} [/tex]
[tex] \sin J = 0.43820... [/tex]

(10, 15) and (8,3). Write the equation of the line in slope-intercept
(y = mx + b) form.
Answer:
[tex]y=6x+-45[/tex]
Step-by-step explanation:
Given the following question:
Point A = (10, 15) = (x1, y1)
Point B = (8, 3) = (x2, y2)
To find the answer we first must find the slope which we will find by using the formula for slope or rise over run. Then we use the formula for slope intercept, substitute the values, and then solve for b.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{3-15}{8-10}[/tex]
[tex]3-15=-12[/tex]
[tex]8-10=-2[/tex]
[tex]=\frac{-12}{-2} =-12\div-2=6[/tex]
[tex]m=6[/tex]
Now we have the slope find the slope intercept:
[tex]y=mx+b[/tex]
[tex]y=15[/tex]
[tex]m=6[/tex]
[tex]x=10[/tex]
[tex]15=6(10)+b[/tex]
[tex]6\times10=60[/tex]
[tex]15=60+b[/tex]
[tex]60-60=0[/tex]
[tex]15-60=-45[/tex]
[tex]-45=b[/tex]
[tex]b=-45[/tex]
[tex]y=6x+-45[/tex]
Your answer is "y = 6x + -45."

The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.
What is the cost of 3 sweatshirts?
PLEASE SHOW HOW YOU GOT ITTT
I WILL MARK BRAINILIST
Answer:
$68.25
Step-by-step explanation:
1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.
[tex]175 * 13 = 2275[/tex] [tex]2275/100=22.75[/tex]2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.
[tex]22.75 * 3[/tex] [tex]68.25[/tex]Therefore, the cost of 3 sweatshirts is $68.25.

Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 8 , then
sum = 180° × 6 = 1080°
note there are 4 angles congruent to ∠ 1 and 1 angle congruent to ∠ 2
sum the interior angles and equate to 1080
5(10x + 15) + 2(14x) + 6x - 3 = 1080 ( distribute parenthesis on left side )
50x + 75 + 28x + 6x - 3 = 1080 ( simplify left side )
84x + 72 = 1080 ( subtract 72 from both sides )
84x = 1008 ( divide both sides by 84 )
x = 12 → option d
--------------------------------------------------------------------
∠ 1 = 10x + 15 = 10(12) + 15 = 120 + 15 = 135°
∠ 2 = 14x = 14 × 12 = 168°
∠ 3 = 6x - 3 = 6(12) - 3 = 72 - 3 = 69°
the largest interior angle is 168° → option b

Fred purchased a jacket for $20 and 5 T-shirts. Each T-shirt cost the same amount. The total cost was $85. How much did each T-shirt cost?
Answer:
Each t-shirt cost 13 dollars.
Step-by-step explanation:
Since the jacket was 20 bucks, we can set that aside:
85-20=65
Now that we've set that aside, there are five t-shirts. If they all cost the same, that means we can divide!
65/5=13
How to check?
Use inverse operations: 13*5=65
Re-add the 20 bucks from the jacket, and the bill is complete again! Use inverse operations: 13*5=65
Each shirt costs $13.

Justin is packing a container with books. The dimensions of each book are 8 inches by 6 inches by 2 inches. • The dimensions of the container are 16 inches by 12 inches by 12 inches. . All of the books and the container are rectangular prisms. Part A How many books can fit in the container if the books are packed so that there is no unused space in the container? Enter your response in the first response box. Part B Each book weighs 2 pounds. The maximum weight the container can hold is 40 pounds. What is the greatest number of books that can fit in the container without going over the container's weight limit? Enter your response in the second response box.
By finding the quotient between the volumes, we will see that 24 books can be fit on the container, and by weight, the container can hold 20 books.
How many books can be fitted on the container?Remember that the volume of a rectangular prism of length L, width W, and height H is given by:
V = L*W*H
Then the volume of each book is:
V = 6in*2in*8in = 96 in^3
And the volume of the container is:
V' = 16in*12in*12in = 2,304 in^3
The number of books that fit in the container is given by:
N = V'/V = 2,304 in^3/96 in^3 = 24
How many books the container can hold?Each book weighs 2 pounds, and the container can hold 40 pounds, then we need to solve the linear equation:
2*x = 40
To get the maximum number of books that the container can hold:
x = 40/2 = 20
x = 20
The container can hold a maximum of 20 books.

James is flipping a coin twice. He says the probability that he’ll get tails both times is 1/2. Which of these is true?
James flipping the coin is an illustration of probability
James' claim is false
How to determine the true statement
The sample space of a coin is:
S = {H,T}
So, the probability of obtaining a tail is:
P(T) = n(T)/n(S)
This gives
P(T) = 1/2
When the coin is flipped twice, the probability that he’ll get tails both times is
P(T and T) = 1/2 * 1/2
Evaluate the product
P(T and T) = 1/4
From the question, he says the probability that he’ll get tails both times is 1/2.
Hence, James' claim is false

The measure of ∠H is 180 degrees, which is a straight angle.
What is a straight angle?An angle with a measure of exactly 180 degrees is called a straight angle. It is an angle with arms that point in opposing directions from the vertex and unites to make 180°.
The given measure of ∠H is (11x - 29).
To determine the measure of ∠H when x = 19, we can simply substitute x = 19 into the expression for the measure of ∠H:
∠H = 11x - 29
∠H = 11(19) - 29
∠H = 209 - 29
∠H = 180
Here, ∠H has a measure of 180 degrees, which is a straight angle.
Therefore, the measure of ∠H when x = 19 is 180 degrees.

A car valued at $14,000 depreciated 18% per year. After how many years will the value have depreciated to $1000?
Answer:
Little more than 5 years
Step-by-step explanation:
Given the following question:
Original value of the car is $14,000
18% depreciated or diminish in value per year.
How many years would it take for the cars value to reach $1000?
To find the answer we must first find 18% of the 14,000 speaking how that's how much the car value diminishes in a year.
18% of 14000:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{18\times14000}{100} =18\times14000=252000\div100=2520[/tex]
[tex]=2520[/tex]
18% of 14000 is 2520, which means each year the cars value depreciates $2520 dollars.
[tex]14000-2520=11480-2520=8960-2520-6440-2520=3920-2520=1400[/tex]
[tex]=1400[/tex]
Which means it will take a "little more than 5 years" for the cars value to reach $1000.
