A ball is launched into the sky at 54.4 feet per second from a 268.8 meter tall building. The equation for the ball’s height, h, at time t seconds is h = -3.2t^2 + 54.4t + 268.8. When will the ball strike the ground?
Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2
T = 7.41 seconds

16d + 5 = -10
what is d?
Answer:
d = -15/16
Step-by-step explanation:
To solve for D, you have to get D alone on one side of the equation (one side of the equal sign).
So get rid of the other numbers that are being added or subtracted to d first. To do that, you have to do the opposite of what is being done.
So u have +5 on the left, you have to minus it to get rid of it. Whatever you do on one side of the equation, you have to do to the other side
so 16d +5 minus 5 = -10 minus 5
the 5 cancels out on the left and -10 - 5 = -15
now you have 16d = -15
Now you have to get rid of the 16. It's being multiplied to d so to do opposite is to divide it by 16. And whatever you do on one side, u have to do on the other.
16d divided by 16 = -15 divided by 16
16d/16 = d -15/16
So d = -15/16
For the expression, value of d is,
⇒ d = - 15/16
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 16d + 5 = - 10
Now, We can solve the expression as;
⇒ 16d + 5 = - 10
Subtract 5 from both side;
⇒ 16d + 5 - 5 = - 10 - 5
⇒ 16d = - 15
Divide by 16 both side;
⇒ d = - 15/16
Therefore, For the expression, value of d is,
⇒ d = - 15/16

answeeeeeeeeeeerrr thank you
Answer:
x = 52
m<ACD = 159
m<ACB = 21
Step-by-step explanation:
1) Set up an equation.
2x + 55 = 3x + 3 (the two interior angles on the opposite of the triangle and the exterior angle are equal to the exterior angle)
2) Solve for x.
2x + 55 = 3x + 3
-x + 55 = 3
-x = -52
x = 52
3) Substitute 'x' into each angle required to find m<ACD and m<ACB.
m<ACD = 3(52) + 3
= 156 + 3
= 159
CHECK:
2(52) + 55 = 159
104 + 55 = 159
159 = 159
m<ACB + m<ACD = 180
m<ACB + 159 = 180
m<ACB = 21

A biologist is recording the loss of fish in a pond. He notes the number of fish, f, in the pond on June 1. On July 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on June 1. What is the number of fish in the pond on June 1?
Which equation can be used to find the number of fish in the pond on June 1?
63−f=52
f−52=−63
f−52=63
f−63=−52

X = -7
4x - 4y = 12
Submit
Answer:
Point Form:
( − 7 , − 10 )
Equation Form:
x = − 7, y = − 10
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
y = -10
Step-by-step explanation:
4x - 4y = 12
Substitute the x with -7, since it has been given.
4(-7) - 4y = 12
-28 - 4y = 12
Add 28 onto both sides
-28 + 28 - 4y = 12 + 28
-4y = 40
Divide by -4 to isolate the variable
-4y/-4 = 40/-4
y = - 10
Check:
Substitute the y and x
4x - 4y = 12
4(-7) - 4 ( -10 ) = 12
-28 + 40 = 12
12 = 12
or.....
try to see if x stays as -7
4x - 4y = 12
4x - 4 (-10) = 12
4x + 40 = 12
Subtract 40 onto both sides
4x + 40 - 40 = 12 - 40
4x = -28
Divide by 4 onto both sides to isolate the variable
4x/4 = -28/4
x = -7
And it's correct

Answer:
x = 65.4
Step-by-step explanation:
Formula For Cos: cos (x°) = adjacent/hypotenuse
Adjacent = 5
Hypotenuse = 12
cos (x) = adjacent/hypotenuse
cos (x) = 5/12
x = cos⁻¹ (5/12)
x = = 65.3756816478359
x = 65.4 (rounded)
Tip: cos⁻¹ is inverse of cos.
Therefore, x = 65.4

What is the sum of 2x+1 and its opposite?
Answer:
Zero. The sum of anything and it's opposite is zero, that's how an opposite is defined . In this case, the opposite of 2x+1 is -(2x+1)=-2x-1 by the distributive property . Adding like terms, 2x+-2x+1+-1=0+0=0.
-3p>-48 Solve the inequality
9514 1404 393
Answer:
p < 16
Step-by-step explanation:
Dividing the inequality by a negative number will reverse the comparison.
-3p > -48
(-3p)/(-3) < (-48)/(-3) . . . . divide both sides by the coefficient of p
p < 16
_____
Alternate solution
Add 3p+48 to both sides.
-3p +(3p +48) > -48 +(3p +48)
48 > 3p
Divide both sides by 3; no reversal is necessary.
16 > p . . . . . same answer as above, without the comparison reversal
