Answer:

32% of his bats were stuck out.

Step-by-step explanation:

emerson struck out 112 times out of the total of 350 times. therefore, this can be represented as the fraction 112/350, which can be simplified to 8/25.

Step-by-step explanation:

she wrote it to solve the total amount spent on both T shirt.

30+6x=20+8x-8x

30+6x-8x=20

30-30-2x=20

-2x=20-30

-2x/-2=-10/-2

Notes:

The sign of the coefficient of the quadratic equation determines if the vertex is a minimum or maximum. Positive looks like ∪ so has a minimum. Negative looks like ∩ so has a maximum.
Maximum/minimum height is the y-value of the vertex.
Time to reach maximum height is the x-value of the vertex (which is also the Axis-Of-Symmetry).

Answer: 4) maximum

5) 20.1 ft

6) 2 seconds

Step-by-step explanation:

4) h(t) = -16t² + 256t

↓

the coefficient is negative so it looks like ∩.

Therefore, it has a maximum.

5) h(t) = -16t² + 30t + 6

$\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(30)}{2(-16)}=\dfrac{-30}{-32}=\dfrac{15}{16}\\\\\\\text{Maximum: }h\bigg(\dfrac{15}{16}\bigg)=-16\bigg(\dfrac{15}{16}\bigg)^2+30\bigg(\dfrac{15}{16}\bigg)+6\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{-225}{16}+\dfrac{450}{16}+\dfrac{96}{16}\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{321}{16}\\\\\\.\qquad \qquad \qquad \qquad \approx20.1$

6) h(t)=-16t²+64t+80

$\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(64)}{2(-16)}=\dfrac{-64}{-32}=2$

3. Encontrar la medida de cada angulo en grados.

Bas_tet [7]

Answer:

En español:

A. Rotación de tres cuartos en sentido antihorario.

3/4 = 270 grados

B. Cinco sextos de rotación en sentido antihorario.

5/6 = 300 grados

C. Diez octavos de rotación en el sentido de las agujas del reloj.

10/8 = 450 grados

D. Un quinto de rotación en el sentido de las agujas del reloj

1/5 = 72 grados

In English:

a. Three-quarter rotation counterclockwise.

3/4 = 270 degrees

b. Five sixths of rotation counterclockwise.

5/6 = 300 degrees

c. Ten-eighths of a clockwise rotation.

10/8 = 450 degrees

d. One-fifth clockwise rotation

1/5 = 72 degrees
