h(t)=- 16t^2 +16t+12 zeros of the parabola

Answers

Answer 1

Step-by-step explanation:

h(t) = -16t² + 16t + 12

h(t) = -4(4t² - 4t - 3)

h(t) = -4(2t - 3)(2t + 1)

When h(t) = 0, we have t = 1.5 or t = -0.5.

Hence the zeroes are 1.5 and -0.5.

What is the answer to -2.6f + 0.7f - 12 -9
Simplify if needed
DUE TODAY!!!!!!

Answers

Answer:

= -1.9f - 21

Step-by-step explanation:

Let's simplify

-2. 6f+ 0.7f- 12 - 9

= - 2.6f+ 0.7 f + - 12 + - 9

Combine like terms

= - 2.6 f+ 0.7 + - 12 + - 9

= (-2.6f + 0.7f ) + ( - 12+-9)

=1.9f+ -21

6. All angles in the figure below are right angles. What is the area of the figure? (1 point)

Answers

Answer:

Option (4)

Step-by-step explanation:

Area of the figure given in the picture = Area of large rectangle - Area of rectangle A

Area of rectangle A = Length × Width

                                 = [9 - (2 + 4)] × 3

                                 = 3 × 3

                                 = 9

Area of the large rectangle = Length × Width

                                             = 9 × 5

                                             = 45

Therefore, area of the given figure = 45 - 9

                                                          = 36

Option (4) will be the correct option.

[tex]\frac{n}{7}[/tex] - 12 = 5n + 5

Answer:

n= -3.5

Step-by-step explanation:

n/7 - 12 = 5n +5

+12            +12

n/7 = 5n+17

n = (5n+17)*7

n = 35n + 119

Hey PLS PLS I WILLL GIVE BRAINLIEST AND THANK YOU ALSO ANSWER THE EQUATION THEN PUT THE ANSWER YOU GOT IN ONE OF THE BLANK BOXES

Answers

Answer:

x=9 B

Step-by-step explanation:

3x=27

divide both sides by 3 to get the x alone

28/3=9

Answer:

B: Divide both sides by 3

Step-by-step explanation:

The reason why is because you want to get x by itself and right now it looks like it is married (multiplied) to 3. To get it by itself, you have to get a divorce (be divided). Therefore, you would do 3x/3=x. You would then also have to divide the 27 on the other side. X then should equal 9.

Zeke has swim club every 2 days and robotics club every 8 days.
This month, he has swim club on the 2nd day of the month and robotics club on the 8th day of the month.
Zeke says that the first time he will have both clubs on the same day is the 16th day of the month because the LCM of 2 and 8 is 16.

Answers

Answer: No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month

Step-by-step explanation:

All you have to do is fine the least common multiple of 2 and 8 which is eight so obviously zeke is incorrect because they said the least common multiple was 16 and it is not. zeke multiplied 2 and 8 which is not what you’re supposed to do to get the lcm.

No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month

Answer:

  a) x = 14

  b) NP = 2 2/9; NL = 2 7/9

Step-by-step explanation:

a) The similarity statement tells you that angle P and angle L have the same measure:

  angle L = angle P

  3x +18 = 60

  x + 6 = 20 . . . . . divide by 3

  x = 14 . . . . . . . . . subtract 6

__

b) The proportional segments are ...

  PN/NQ = LN/NM

  y/3.2 = (5 -y)/4

  5y = 4(5 -y) . . . . . multiply by 16

  9y = 20 . . . . . . . . add 4y

  y = 20/9 = NP

  5 -y = (45 -20)/9 = 25/9 = NL
