In a physics lab, an artifact is dropped from the roof of the school building, 98 feet above the ground. The height ݄ (in feet) of the ball above the ground is given by the function h(t)=-16t^2+98, where t is the time in seconds.

Answer:

AC = 36

Step-by-step explanation:

since these triangles are similar, we can use the triangle similitary theorem. This means that the sides are proportional to each other.

ef/bc = 5/45 (1/9) = ed/ba =  2/18 (1/9)

we can see the sides are in a ratio of 1:9, and plug it in the proportion

df/ac = 1/9

4/ac = 1/9

cross multiply and we get that ac = 36

Answer:

B. ∠EAB and ∠CAD;

D. ∠CAB and ∠DAE

Step-by-step explanation:

Vertical angles are two angles formed directly opposite each other when two straight lines crosses or intercepts each other. Vertical angles are of equal measure to each other.

Thus, from the diagram given,

<CAD is vertically opposite to <EAB, also,

<CAB is vertically opposite to <DAE.

Thus, the vertical angles are:

∠EAB and ∠CAD;

∠CAB and ∠DAE

Circumference of the barrel is 51.81 unit

Given that;

Diameter of barrel = 16.5 unit

Find:

Circumference of the barrel

Computation:

Radius of barrel = 16.5/2 unit

Radius of barrel = 8.25 unit

Circumference of the barrel = Circumference of the circle

Circumference of the barrel = 2πr

Circumference of the barrel = 2(3.14)(8.25)

Circumference of the barrel = 51.81 unit

Step-by-step explanation:

Part A: 24.50 feet, Part B: 46.68 square feet, I just took the test and got this right!

The perimeter of the figure is [tex]24.50[/tex] and area of the figure is [tex]45.68[/tex] square feet.

What is Area of Circle?

In geometry, the area enclosed by a circle of radius r is πr². Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159

According to question, the radius of the partial circle with center A is 4 feet.

We have to find the perimeter and area of the figure.

Perimeter of the figure=2πr×[tex]\frac{3}{4}[/tex] +[tex]4\sqrt{2}[/tex]

=2×[tex]3.14[/tex]×[tex]4[/tex]×[tex]0.75+4[/tex]×[tex]1.414[/tex]

[tex]=24.50[/tex]

Area of figure=[tex]\frac{3}{4}[/tex] πr²+[tex]r^{2}[/tex]×[tex]\frac{1}{2}[/tex]

=[tex]0.75[/tex]×[tex]3.14[/tex]×[tex]16[/tex][tex]+16[/tex]×[tex]0.5[/tex]

[tex]=37.68+8[/tex]

[tex]=45.68[/tex]

Hence, we can conclude that the perimeter of the figure is [tex]24.50[/tex] and area of the figure is [tex]45.68[/tex] square feet.

Answer:

65% of the orginal fee or $130.

Step-by-step explanation:

You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:

1:  100% = 10% + 25% + 65%

2:  200 = 20 + 50 + 130

3:  200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)

All of them basically mean the same thing it is just a matter of how you need it written.

Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.

Rodney has to pay $200 in three installments.

The third installment will be:

= Percentage in total - Percentages paid already

= 100% - 10% - 25%

= 65%

The third installment is therefore:

= Percentage to be paid x Amount

= 65% x 200
