Answer:
Step-by-step explanation:
Given the the height covered by the ball modeled by the equation
y= -4.9x²+12
Since we are not told what to find, we can as well find the time taken by the ball to reach the ground.
The ball hits the ground when y = 0. Substitute y = 0 into the equation and calculate x;
y= -4.9x²+12
0 = -4.9x²+12
Subtract 12 from both sides
0-12 = -4.9x²+12-12
-12 = 4.9x²
x² = -12/4.9
x² = 2.448
x = √2.448
x = 1.57s
Hence we can say that the ball hits the ground after 1.57s.

Determine the leading coefficient of the polynomial p, which has exactly three roots: -1, 1 and 2, and for which p(3) = 24 is true.
Answer:
The polynomial is [tex]x^3-2x^2-x+2[/tex]
Leading coefficient is 1
Step-by-step explanation:
We need to determine the leading coefficient of polynomial p having roots
-1,1 and 2 and p(3)=24
Roots of polynomial are: -1,1,2
We can write them as:
x=-1, x=1, x=2
x+1=0, x-1=0, x-2=0
or:
(x+1)(x-1)(x-2)=0
Multiplying the terms to find the polynomial:
[tex](x+1)(x-1)(x-2)=0\\(x(x-1)+1(x-1))(x-2)=0\\(x^2-x+x-1)(x-2)=0\\(x^2-1)(x-2)=0\\x^2(x-2)-1(x-2)=0\\x^3-2x^2-x+2=0[/tex]
So, The polynomial is [tex]x^3-2x^2-x+2[/tex]
The leading coefficient is the coefficient with highest power So, in polynomial we have highest power [tex]x^3[/tex] so, leading coefficient is 1

if the expression (2y^a)^4 is equivalent to 16y^8, what is the value of a
Answer:
A = 2.
Step-by-step explanation:
When raising power to power and there is a base with a exponent and a coefficant, you need to know that the a exponent only belongs to the y. The 2 has a invisible 1 exponent. The new expression is now (2^1 y^a)^4 = 16y^8. Now it is time to solve it. 1x4 = 4 so it is (2^4 y^a) = 16y^8. 2^4 is also 2x2x2x2 which equals 16. Now for the a exponent, 8/4 = ?. 2. The new expression is 16y^2 and a = 2.

SSS
Step-by-step explanation:
I can identify that these triangles are congruent by using the SSS (Side, Side, Side) postulate theorem. I know this because first, second, and home triangle share the same side as the third, second, and home triangle, meaning they are congruent, so are the other sides of the angle since the question states they are congruent.

Anchara drops a penny from a height of 60 feet above the ground. The equation h=-16t^2 + 60 models the penbys height h i feet as a function of time t in seconds whatvare the solutions
Answer:
t = 1.94 seconds
Step-by-step explanation:
we have to solve the following polynomial equation:
-16t² + 60 = 0
16t² = 60
t² = 60/16 = 3.75
t = √3.75 = 1.936491673 seconds
the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option

A regular decagon is rotated n degrees about its center, carrying the decagon onto itself. The value of n could be:
1. 10 degrees
2. 150 degrees
3. 225 degrees
4. 252 degrees
Answer:
252°
Step-by-step explanation:
Given
Shape: Decagon
Required
Determine the value of n
A Decagon has 10 sides and a complete rotation takes 360°
First, we need to calculate the angle of each rotation as follows.
Each Rotation = ⅒ * 360°
Each Rotation = 360°
Next, we determine the possible values of n.
The statement is represented as "possible values of n" because n can assume infinite number of values.
However, n must be a multiple of 36
From the list of given options.
10, 150 and 225 are not multiples of 36
Only 252 happens to be a multiple of 36 from the list of given options.
Hence, option D answers the question [base on the given options]
A decagon is a ten-sided polygon.
The value of n could be 252 degree.
Since, A Decagon has 10 sides
The angle made in one complete rotation is 360 degree.
Now find angle made in each rotation is,
[tex]=\frac{360}{10}=36degree[/tex]
Now, we have to find possible values of n.
Since, n must be a multiple of 36
Apply hit and trial from given option.
We observe that from given options, only 252 degree is multiple of 36.
Therefore, value of n could be 252 degree.
Hence, option 4 is correct.

Answer:
u = -7/4
Step-by-step explanation:
This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
Answer:
[tex]\displaystyle m_u=-\frac{7}{4}[/tex]
Step-by-step explanation:
Perpendicular Lines
If two lines t and u are perpendicular and have slopes mt and mu respectively, then the following relationship is satisfied:
[tex]m_t\cdot m_u=-1[/tex]
Knowing line t has a slope of \frac{4}{7}, then the slope of line u can be found by solving for mu:
[tex]\displaystyle m_u=-\frac{1}{m_t}[/tex]
[tex]\displaystyle m_u=-\frac{1}{\frac{4}{7}}[/tex]
Operating:
[tex]\mathbf{\displaystyle m_u=-\frac{7}{4}}[/tex]
Write an equation of the line passing through the point (2,8) that is perpendicular to the line 2x-3y=7
Answer:
y = (-3/2x) + (35/4)
Step-by-step explanation:
So the perpendicular line will have a slope that is the opposite reciprocal of the other line's slope. Solve for the original line's slope first:
2x - 3y = 7 --> -3y = -2x + 7 --> y = (2x/3) - (7/3)
So, the slope of the perpendicular line will be (-3/2x)
Solve for the y-intercept of the perpendicular like by using the linear equation and substituting in (2,8):
8 = (-3/(2*2)) + b --> (32/4) = -(3/4) + b --> b = (35/4)
So, y = (-3/2x) + (35/4)

Amanda is making white oatmeal cookies with raisins and pecans for her club.The recipe makes seventeen of the big,chewy kind of oatmeal cookies with lots of raisins and nuts.It takes one-fourth of a cup of nuts and one-half of a cup of raisins just for the seventeen cookies!There are thirty-four members in Amanda's club .If she makes exactly thirty-four cookies,how many cups of nuts will she need ?
Answer:
1/2 cup of nuts
Step-by-step explanation:
If it takes 1/4 cups of nuts to make 17 cookies
Then it takes 1/4 * 1/17 = 1/68 cups of nut to make 1 cookie
So,
If 1/68 cups of nut are needed to make 1 cookie
To make 34 cookies we need;
34 * 1/68 = 1/2 cup of nuts

b. Solve the system to find the price of one can of soup and the price of one loaf of bread
Answer:
a) cblo
2)$3.44
Step-by-step explanation:
4 cans and 3 loaves=11.67
8 cans and 1 loaf= 12.89.
Set up equation:
x=cans
y=loaves
[tex]4x+3y=11.67\\8x+y=12.89[/tex] This is the answer for question A.
Multiply eq1 by 2:
[tex]8x+6y=23.34[/tex]
Subtract eq3 by eq2:
[tex]5y=10.45\\y=2.09[/tex]
Substitute:
[tex]8x+2.09=12.89\\8x=10.8\\x=1.35[/tex]
One can of soup and one loaf of bread=
[tex]1.35+2.09 or 3.44[/tex]
So:
[tex]$3.44[/tex]
Hope this helps :D Please hit the crown if u can !!
a. The equation should be
4x + 3y = $11.67
8x + y = $12.89
b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09
The calculation is as follows:
here we assume the soup be x and bread be y
So, the equations are
4x + 3y = $11.67 .........(1)
8x + y = $12.89.........(2)
Here we need to multiply by 2 in equation 1
8x + 6x = $23.34
8x + y = $12.89
5y = $10.45
y = $2.09
Now x should be
8($2.09) + y = $12.89
x = $1.355
