The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?

Answers

Answer 1

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Not sure if this is correct but:

38.4 is 48% of 80

Step-by-step explanation:

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Solve the following equations:

x/3+1=7/5

Answers

Answer:

8/5..............…is the answer

Answer:

Standard Form: 6/5 Mixed Number: 1 1/5 Decimal: 1.2

Step-by-step explanation:

1. Subtract 1 from both sides of the equation

x/3 + 1 = 7/5

x/3 + 1 - 1 = 7/5 - 1

2. Simplify

2a.

x/3 + 1 - 1 = 7/5 - 1

x/3 = 7/5 - 1

2b.

x/3 = 7/5 - 1

x/3 = 2/5

3. Multiply all terms by the same value to eliminate fraction denominators

x/3 = 2/5

3 x x/3 = 3 x 2/5

4. Simplify

4a. Cancel multiplied terms that are in the denominator

cross out the threes in 3 x x/3 then you should get x = 3 x 2/5

4b. Multiply the numbers

x = 3 x 2/5

x = 6/5

And your answer should be 6/5|

Perimeter of a triangle

The perimeter of a triangle is the sum of all the sides of the triangle.

According to the figure shown, the perimeter of the shape is given as:

P = 2x²+1 + 4x+4 + x²+12x
P =3x² + 16x + 5

Factorize

P =3x² + 15x + x+ 5

P = 3x(x + 5) + 1(x+5)

P = (3x + 1)(x+5)

Hence the perimeter of the triangle as a simplified polynomial is (3x + 1)(x+5)

(c) R: supplementary to 32°, 180°-32° = 148°
