A ball is thrown into the air with an initial upward velocity of 48 ft/s. It height h in feet after t seconds is given by the function h (t)=-16t^2+48t+4.
In how many seconds will the ball reach its maximum height?
Answer:
Step-by-step explanation:
h(t)=-16t^2+48t+4
dh/dt=-32t+48
d2h/dt2=-32
Since acceleration is always negative when the velocity, dh/dt=0, it will occur at the maximum height.
dh/dt=0 when
-32t+48=0
-32t=-48
t=1.5 seconds
Without calculus, the vertex of a parabola will be at -b/(2a) of the quadratic equation. In this case
-48/(2(-16))
-48/-32
1.5 seconds

18.5 ft, 6 ft, 17.5 ft
Answer:
yes, it is a right triangle.
Step-by-step explanation:
you could use the pythagorean theory to check:
[tex]a^{2} + b^{2} = c^{2}[/tex]
(the hypotenuse is the longest side)
[tex]17.5^{2} + 6^{2} = 18.5^{2}[/tex]
[tex]306.25 + 36 = 342.25[/tex]
[tex]342.25 = 342.25[/tex]

I got this find the perimeter of the rectangle length= 2x width= 10 + x i dont understand, can someone explain???
Answer:
6x + 20
Step-by-step explanation:
the formula for the perimeter of the rectangle is 2 x (length + width)
from the question length = 2x
width = 10 + x
2(2x + 10 + x)
2 (3x + 10 )
6x + 20

Answer:
7) 65°8) 25°Step-by-step explanation:
Question 7
Angle formed by 2 chords is half of the sum of the intercepted arcs
x = 1/2(72° + 58°) = 1/2(130°) = 65°Question 8
Angle formed by 2 secants is half of the difference of the intercepted arcs
x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°Pls help with finding slope and y intercept from 2 points‼️‼️❗️❗️❗️❗️
step 1: plot your points.
step 2: find the rise over run
step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)
step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)
then put in y intercept form: y=2/5x+8

Colton solved an equation incorrectly, as shown below:
Step 1: x - 13 = 26
Step 2: x = 26 - 13
Step 3: x = 39
Which statement best explains why Step 2 is incorrect in Colton's solution? (4
points)
He did not divide 26 by 13.
He did not multiply 26 by 13.
O He did not subtract 13 from 26.
He did not add 13 to 26.
Answer:
He didn't add 13 to 26
Step-by-step explanation:
he would need to add -13+13 to get rid of it. and add 13 on the other side 13+26
He added instead of subtracting. The answer is the first.
How many solutions do these have
Answer:
See explanation below
Step-by-step explanation:
a. One solution (p = 1/4)
b. Infinite amount of solutions (No matter what value for p is, the equation will always be 7=7)
c. One solution (p = 12)
d. No solution (No matter what value for p is, the equation will always be 3 = -1, which wouldn't work)
Design An art class is making a mural for their school which has a triangle drawn in the middle. The
length of the bottom of the triangle is x. Another side is 13 more than two times the length of the
bottom of the triangle. The last side is 10 more than the bottom of the triangle. Write and simplify an
expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?
Answer: [tex]4x+23[/tex]
Step-by-step explanation:
Given
The length of the bottom of the triangle is x
Another side is [tex]2x+13[/tex]
The last side is [tex]x+10[/tex]
Perimeter is the sum of the side of triangles
[tex]\Rightarrow \text{Perimeter}=x+2x+13+x+10\\\Rightarrow \text{Perimeter}=4x+23[/tex]
f(x) = 3x - 3
g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23
Probability of blue is 0.4 red 0.3 yellow 0.3 there are 30 blue cubes in box what total number of cubes in box
Answer:
75
Step-by-step explanation:
The computation of the total number of cubes in box is shown below:
Given that
The probability of blue = 0.4
For red it is 0.3
And, for yellow it is 0.3
As if there is 30 blue cubes in a box
So for red it is = 30 × 0.3 ÷ 0.4 = 22.5
And, for yellow = 30 × 0.3 ÷ 0.4 = 22.5
Now the total number of cubes in a box is
= 30 + 22.5 + 22.5
= 75
2/5+7/15 in its simplest form
Answer:
13/15
Step-by-step explanation:
First convert the fractions to have a common denominator
2/5 = x/15
Cross multiply
2 × 15 = 5 × x
30 = 5x
Divide both sides by 5 to isolate the variable
30 ÷ 5 = x
6 = x
Plug x into the new fraction
6/15
Now add this to the other fraction
6/15 + 7/15
Only add the numerators. The denominators will remain the same number
6 + 7 / 15
13/15
It cannot be reduced anymore so this is simplest form

Determine the slope-intercept equation of a line with a slope of 3/2 that passes through (2, -1).
Answer:
[tex] \orange{ \bold{y = \frac{3}{2}x -4 }}[/tex]
Step-by-step explanation:
Slope of line (m) = [tex] \frac{3}{2} [/tex]
Line passes through the points [tex] (2,\:-1)=(x_1, \:y_1)[/tex]
Equation of line in point slope form is given as:
[tex] y-y_1 =m(x-x_1)[/tex]
Plug the values of m, [tex] x_1\: \&\: y_1[/tex] in the above equation, we find:
[tex]y - ( - 1) = \frac{3}{2} (x - 2) \\ \\ y + 1 = \frac{3}{2}x - \frac{3}{2} \times 2 \\ \\ y + 1 = \frac{3}{2}x -3 \\ \\ y = \frac{3}{2}x -3 - 1 \\ \\ \purple{ \bold{y = \frac{3}{2}x -4 }}\\ \\ [/tex]
This is the required equation of line in slope-intercept form.
