Answer:
x = 0 and x = 1
Step-by-step explanation:
Given that,
A football is kicked into the air. The height of the football can be modeled by the equation :
[tex]h = -16x^2 + 16x[/tex]
Where
h is the height reached by the ball after x seconds
When it touches the ground, h = 0
So,
[tex]-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1[/tex]
So, it will touch the ground at x = 0 and x = 1 seconds.

Answer:
5x + 3y = 12
Step-by-step explanation:
We are given the line 5x + 3y = 6 and are to find the equation of a new line that is parallel to this one and goes through (3, -1).
Parallel lines have the same slope. The slope of the given line is determined by the coefficients 5 and 3 visible above. Therefore, the form of the equation of the new line is 5x + 3y = C, where we must determine the value of C.
Substitute 3 for x and -1 for y in 5x + 3y = C, obtaining: 5(3) + 3(-1) = C. Then 15 - 3 = 12 is the constant value, and the equation of the 'new line' is
5x + 3y = 12

The sales rate is 8%. If Janelle buys a gymnastics mat priced at $87 , how much tax will she pay?
Answer: $6.96
Step-by-step explanation:
To find out what 8% of $87 is, you have to convert the 8% into decimal form which is 0.08. Then you have to multiply that by $87
87*0.08 = 6.96
Now, we know $6.96 is 8% of $87 which is how much she will be paying in tax
Gabby draws a line segment to connect points (2,1) and (7,4). She draws a second lien segment that is parallel to the first one by connecting the points at (2,3) and (7,6). If she wants to draw a third line segment parallel to the ones she has already drawn, what ordered pairs could she use?
9514 1404 393
Answer:
(2,5) and (7,8)
Step-by-step explanation:
Gabby has increased the y-coordinates by 2 units to get her first parallel line. She can do the same thing again to get the second parallel line.

Regina rolls a fair, six-sided die every week, and her allowance for that week is twice the
number she rolls on the die. Write an expression to represent Regina's allowance for the
week where n represents the number that Regina rolls on the die that week.
Write your answer in the box.
Answer:
6*2=n
Step-by-step explanation:
Well, if its a 6 sided die, and she gets twice the amount, then 6*2 and since the total = n 6*2=n The Total of the equation would be 12 instead of n
Christie's Auction sold a painting for
$24,500. It charges all buyers a 15%
premium of the final bid price. How much
did the bidder pay Christie's?
The price that bidder pays to Christie's is $2130.4.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
And to convert a fraction or a decimal into percentage, they are multiplied by 100.
Given that,
The price for which painting is sold is $24,500.
The percentage of premium price of the final bid is 15%.
Suppose the price paid by the bidder be x.
Then, as per the question the following equation can be written for the price of painting,
x + 15% of x = 24500
=> x + (15/100)x = 24500
=> 115x/100 = 24500
=> x = (24500 × 100) ÷ 115
=> x = 2130.43
Hence, the amount paid to Christie's is $2130.4.

In 42 of the 64 years from 1950 through 2014,the S& P 500 finished higher after the first five days of trading (in 2011 there was virtually no change). In 37 out of 42 years, the S&P 500 finished higher for the year. Is a good first week a good omen for the upcoming year? The following table gives the first-week and annual performance over this 64-year period.

First week Higher Lower Total
Higher 37 5 42
Lower 11 11 22
Total 48 16 64

what is the probability that the S&P 500 finished lower for the year?
b) Given that the S&P finished lower after the first five days of trading,
what is the probability that it finished lower for the year?
c) Are the two events "first week performance" and "annual performance"

Addison sells plants. She sold 7 times as many as tomato plants as pepper plants, for a total of 64 plants sold. How many pepper plants did she sell? PLEASE SOMEONE GIVE ME THE ANSWER AHHHH
Answer:
8 pepper plants were sold.
Step-by-step explanation:
Assuming [tex]x=[/tex] the number of pepper plants sold, she sold [tex]7x[/tex] tomato plants and [tex]x[/tex] pepper plants, and since tomato plants sold + pepper plants sold = 64, we can turn this into the equation [tex]7x+x=64[/tex]. To solve this first we combine like terms to get [tex]8x=64[/tex]. Cancel the 8 by dividing both sides by 8 and we get [tex]x=8[/tex], which is the number of pepper plants sold. (We could also multiply x by 7 to get the number of tomato plants sold, which is 56.) Hope this helps!
PS: Please mark brainliest!Dennis buys 32 inches of trim for a craft project. What fraction of a yard does Dennis buy?
Answer:
crrfhjgbnjjjhhbnmlpoutdxcjkougfsweee
Answer:
8/9 OR 32/36, depending on whether or not you need it simplified.
Step-by-step explanation:
We know one yard has 36 inches. Since Dennis buys 32, we'll simply put that over 36 to find our fraction. You'll then get 32/36, and the most simplified form of that is 8/9.

Answer:
Every quadrilateral's 4 angles add up to 360 degrees.
The four angles would be 100° + 7x +37 + 100° + 7x +37 = 360°
200° + 14x + 74° = 360°
14x = 360° - 274
14x = 86
x = 6.1428571429
Step-by-step explanation:
Answer: x=43/7
Step-by-step explanation:
One of the properties of the inner angle of a parallelogram is that the two angles on the same side add up to 180°
100+(7x+37)=180
100+7x+37=180
137+7x=180
137+7x-137=180-137
7x=43
x=43/7≈6.14

Complete the equation of this circle :
Answer:
-2 , 4 , 36Step-by-step explanation:
[tex](x - -2)^{2} + (y - 4)^{2}[/tex]
[tex](x + 2)^{2} + (y - 4)^{2} =36[/tex]
The equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.
The equation of a circle with radius r and center (h, k) is given by:
(x - h)² + (y - k)² = r²
Radius (r) = 6
Center (h, k) = (-3, 4)
Plugging these values into the equation, we have:
(x - (-3))² + (y - 4)² = 6²
(x + 3)² + (y - 4)² = 36
Therefore, the equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.
