Answer:

0.125, or 1/8

Step-by-step explanation:

[tex]\frac{1}{4}*\frac{3}{6}[/tex] You can easily convert these fractions into decimals.

1/4 = 0.25 and 3/6 = 0.50

Therefore, [tex]\frac{1}{4}*\frac{3}{6}[/tex] is the same as (.25)*(.5), this equals 0.125, or 1/8 as a fraction.

Step-by-step explanation:

A ball is kicked 4 feet above the ground with an initial vertical velocity of 51 feet per second. The function h(t)=−16t²+51t+4 represents the height h (in feet) of the ball after t seconds. Using a graph, after how many seconds is the ball 28 feet above the ground? Round your answers to the nearest tenth.

Answers

Answer:

0.6 seconds to 2.6 seconds

Step-by-step explanation:

From the graph the ball reaches 28 feet after 0.574 seconds

and doesn't fall below that until 2.614 seconds

0.574 rounded is 0.6 seconds

2.614 rounded is 2.6 seconds

Answer:

0.57 seconds (see graph)

Step-by-step explanation:

h(t) = -16t² + 51t + 4

h(t) = 28

28 = -16t² + 51t + 4

0 = -16t² + 51t - 24

t1 = 2.613573055

t2 = 0.5739269455 (pick this answer)

The ball will be 28 feet above the ground after 0.57 seconds

find the area of a semi circle with radius 12cm give your answer in terms of pi

Answers

Answer:

72pi

Step-by-step explanation:

The formula for the area of a circle is pi*r^2

Since three radius is 12, then it’s pi*12^2

pi*12^2= 144 x pi but that’s the area of a whole circle so divide by 2 and you get:

72pi

Answer:

226.195 cm²

In terms of pi:

A = (π · 12²) ÷ 2

A = π · 12²

A = π · 144

A = 452.39

1 7/10 - 1 1/2
it has to be a fraction and no links

Answers

First you start solving each mixed fraction:
17/10 - 3/2
Now we have improper fractions; fractions that have a numerator larger than the denominator
Next we will find the common denominator using LCM but what I personally do is I multiply both sides by the opposite fraction’s denominator, like this:
17 x 2 _ 3 x 10 —-> 34 - 30
10 x 2 2 x 10 20 - 20

Now we have 34/20 - 30/20 and with the help of collecting the common denominator, all we have to do now is subtract 30 from 34, and our answer will be 4/20
**when we have the same number as our denominator we only add or subtract the numerator, depending on what question your teacher asks you to answer
*** sum = addition/adding
difference = subtraction/subtracting/taking away
The correct answer is 1/5
At first when you subtract you will get 4/20 however answers should always be in reduce /simplified do answer is
1/5

Write the equation of the line in fully simplified slope-intercept form.

Answers

Answer:

[tex]y=-\frac{1}{4} x-6[/tex]

Step-by-step explanation:

The slope-intercept form is [tex]y=mx+c[/tex], where m is the slope of the line and c is where the line crosses the [tex]y[/tex]-axis.

To calculate [tex]m[/tex] we can use the formula [tex]m = \frac{dy}{dx}[/tex] where [tex]dy[/tex] is the difference in [tex]y[/tex] between two points and [tex]dx[/tex] is the difference between [tex]x[/tex].

Information we can get from the graph given: [tex]c=-6[/tex]. Since [tex]c[/tex] is the point at which the line crosses the [tex]y[/tex]-axis.

To find [tex]m[/tex] let's get two points from the graph.

Point 1: [tex](4,-7)[/tex]

Point 2: [tex](8,-8)[/tex]

Now use the equation [tex]m = \frac{dy}{dx}[/tex].

[tex]m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}[/tex].

Now we have [tex]m[/tex] and [tex]c[/tex], let's put them back into the general equation.

[tex]y=-\frac{1}{4} x-6[/tex]
