Answer:

It would take the projectile 4 seconds

T = 4

Step-by-step explanation:

g = 32 feets/ seconds (s)

s = 128 feet

t = ?

g = <u>s</u>

g = s t

32 = <u>12</u><u>8</u>

t

Cross multiply

32t = 128

t = <u>12</u><u>8</u>

32

t = 4 seconds

Plssssss help me! What is the area of the shaded portion to the nearest hundredth?
Katarina [22]

Step-by-step explanation:

A1= area of the rectangle

A1= 4yd • 10yd

A1= 40 square yd

A2= area of the part of the circular section

A2= 180°• pi • 4 square yd/360°

A2= 180° • 16yd • pi/ 360°

A2= 16yd•pi/2

A2= 8yd•pi

A2= 25,12yd

A= areo of rhe shaded portion

A= A1-A2

A= 40yd-25,12yd

A= 14,88yd

Which best describes the angles of some parallelograms? A. Four obtuse angles B. Four acute angles C. Two acute and two obtuse a
anyanavicka [17]
Some parallelograms have 2 obtuse and 2 acute angles.  

Parallelograms may have all 90 degree angles as well.  These are also called rectangles.  

When you "bend" a rectangle it naturally forms 2 acute and 2 obtuse angles.

If I had a literal equation that was 1/2f + i = h, what would "i" equal in this equation?
Anni [7]

Answer:

i = h + \frac{1}{2f}

Step-by-step explanation:

\frac{1}{2f} + i = h

Taking \frac{1}{2f} to the other side, you have:

i = h + \frac{1}{2f}

A prism is completely filled with 1120 cubes that have edge lengths of 1/2 in. What is the volume of the prism? Enter your answe
Ronch [10]
Each cube has an edge length of 1/2 inch
V = 1/2 * 1/2 * 1/2
V = 1/8 cu in

There are 1120 of these cubes so the volume of the prism is 1/8 * 1120 = 140 cubic inches.

Can someone check if this is right or did I solve it wrong?
ICE Princess25 [194]

Answer:

f(3x) - 2g(x+1) = 12x - 5

Step-by-step explanation:

You've got f[g(x)] and g[f(x)] correct

However, f(3x) means substitute 3x for x in f(x):

f(3x) = 2(3x) - 3

⇒ f(3x) = 6x - 3

2g(x+1) = 2[4 - 3(x + 1)]

⇒ 2g(x+1) = 2[4 - 3x -3]

⇒ 2g(x+1) = 2[1 - 3x]

⇒ 2g(x+1) = 2 - 6x

f(3x) - 2g(x+1) = (6x - 3) - (2 - 6x)

⇒ f(3x) - 2g(x+1) = 12x - 5
