The height of a baseball thrown from the catcher to first base is modeled by the function h(t) = –0.09t2 + 0.72t + 6, where h is the height of the ball measured in feet and t is the time since being thrown, measured in seconds. The ball is in the air for 10 seconds before being caught. What's the height of the ball at 10 seconds?

The answer is 7209.306

Answer:

[tex]9*10^{11}[/tex]

Step-by-step explanation:

we have

[tex](3*10^{6})*(3*10^{5})[/tex]

we know that

[tex](a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)}[/tex] -----> the bases are multiplied and the exponents are added up

so

in this problem

[tex](3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}[/tex]

[tex]=9*10^{11}[/tex]

Look at where the line crosses the X axis.

Here we see it crosses -2

So your answer is A (-2, 0)

The [tex]x[/tex]-intercept of the graph using the definition of intercepts is [tex](-2,0)[/tex].

Thus, option [tex]1[/tex] is correct.

A point on the y-axis, through which the slope of the line passes, is called as intercept . The point at which the line crosses [tex]x[/tex]- axis is called [tex]x[/tex] intercept and the point at which the line crosses [tex]y[/tex] - axis is called [tex]y[/tex]  intercept .

According to the information provided by the graph,

The line crossed [tex]x[/tex]- axis at [tex]x = -2[/tex].

So, the intercepts of  [tex]x\\[/tex] axis will be [tex](-2,0)[/tex].

The [tex]x[/tex]-intercept of the graph using the definition of intercepts is [tex](-2,0)[/tex].

Answer:

The answer is .4sqr ft

Step-by-step explanation:

That board is 2 feet by 4 feet:

Area = 2 x 4 = 8 sq. ft.

The hole will have an area that is 5% of this value.

8 sq. ft x 0.05 = 0.4 sq. ft.

Answer:

0.4 sq. ft.

That would be 24 inches the cornholes probability is due to the angles and geometric force. If you throw it at the 24 by 48 dimension of thee board the probability for it to actually go in is a small but more likely chance. if you tweak how hard you are tossing' it the more results you will get of width and distance from the hole. Eventually tho you will indefinitely get it in to the hole.

40% would be the answer because it has to equal 100% and 2/5 of it is 40%

Answer:

Sami should invest in 1st case, to get the maximum money.

Step-by-step explanation:

Sami has $500 to invest.

We will use the compound interest formula :

[tex]A=p(1+r/n)^{nt}[/tex]

Case 1:

p = 500

r = 3% or 0.03

t = 4

n = 1

Putting the values in formula we get,

[tex]A=500(1+0.03/1)^{4}[/tex]

[tex]A=500(1.03)^{4}[/tex]

A = $562.75

Case 2:

p = 500

r = 4% or 0.04

n = 1

t = 3

Putting the values in formula we get,

[tex]A=500(1+0.04/1)^{3}[/tex]

[tex]A=500(1.04)^{3}[/tex]

A = $562.43

Case 3:

p = 500

r = 2.5% or 0.025

n = 3

t = 6

Putting the values in formula we get,

[tex]A=500(1+0.025/3)^{6}[/tex]

[tex]A=500(1.0083)^{6}[/tex]

A = $525.42

Case 4:

p = 500

r = 5% or 0.05

n = 1

t = 2

Putting the values in formula we get,

[tex]A=500(1+0.05/1)^{2}[/tex]

[tex]A=500(1.05)^{2}[/tex]

A = $551.25

Comparing all values we can see that case 1 has the highest amount.

Hence, Sami should invest in 1st case, to get the maximum money.

Let the person's arm length be = x

Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.

So, the inequality equation becomes:

[tex]20\leq1.2x\leq40[/tex]

This gives x=[tex]\frac{20}{1.2}=16.66[/tex] or [tex]16\frac{2}{3}[/tex]

or x=[tex]\frac{40}{1.2}[/tex]=33.33 or [tex]33\frac{1}{3}[/tex]

Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.

Answer:

Step-by-step explanation:

Let the arm length of tuxedo be x which varies from 20 inches to 40 inches.

If length of the sleeves is about 1.2 times a person's arm length.

Then the arm length of a person will be 1.2x.

Inequality for the arm length will be

20 < 1.2x < 40

Now we divide this inequality by 1.2

[tex]\frac{20}{1.2}<x<\frac{40}{1.2}[/tex]

16.67 < x < 33.33

This inequality represents the arm length of people having arm length between 16.67 and 33.33 inches.

Step-by-step explanation:

To write an expression that shows 9 * 475 multiply using expanded form an distributive property we break 475 into three numbers

475 can be break into 400 + 70 + 5

Now we multiply by 9

9 x 475

9 x (400 + 70 + 5) (expanded form of 475)

We use distributive property here.

We distribute 9 inside the parenthesis

9 x 400 + 9 x 70 + 9 x 5

Answer:

29.31 cubic inches

Step-by-step explanation:

The dimension of the cylindrical mold is:

Radius (r) = 2 inches

Height of the cylinder (h)= 5 inches

The dimension of the sphere is:

Radius (r) = 2 inches

Lets calculate the amount of wax needed for the cylindrical candle:

A [tex]=\pi \times r^2\times h[/tex]

[tex]A=3.14\times 2^2\times 5=3.14\times 4\times 5=62.8[/tex] cubic inches

Now, lets calculate the amount of wax needed for the spherical mold:

[tex]A=\frac{4}{3}\times \pi \times r^3=\frac{4}{3}\times 3.14 \times (2)^3=\frac{4}{3}\times 3.14\times8=33.49[/tex] cubic inches

So the approximate difference in the amount of wax needed to make a candle from each of these molds is given by:

Amount of wax for the spherical mold subtracted by the amount of wax for cylindrical mold:

[tex]62.80-33.49=29.31[/tex] cubic inches

So the approximate difference in the amount of wax is 29.31 cubic inches.

Option: D is the correct answer.

The k-value is: [tex]\dfrac{-1}{4}[/tex]

The table of values of x and y are given as follows:

    x        y

   -4        1

    8       -2

    12      -3

    20      -5

We know that x and y are said to be in proportional with constant of proportionality k if there is a constant k such that:

       [tex]y=kx[/tex]

for different ordered pair (x,y)

Here for ordered pair (-4,1) we have:

[tex]1=k\times (-4)\\\\i.e.\\\\k=\dfrac{-1}{4}[/tex]

Similarly for all the  other ordered pair we get:

k is a constant and

[tex]k=\dfrac{-1}{4}[/tex]

    Hence, the answer is:

[tex]2^{-10} = \frac{1}{2^{10}} = \frac{1}{1024}[/tex]

A negative power is equal to 1/that to the positive power.

Final answer:

2 to the -10th power equals 1/1024 or 0.0009765625 in decimal form. It is calculated by taking the reciprocal of 2 raised to the 10th power, following the rules of negative exponents.

Explanation:

The student is asking about 2 to the -10th power, which is a mathematical expression involving negative exponents. When dealing with negative exponents, it's important to remember that a negative exponent indicates the reciprocal of the base raised to the absolute value of the exponent. Therefore, to calculate 2 to the -10th power, we use the following steps:

Identify the base (2) and the negative exponent (-10).

Understand that a negative exponent means the reciprocal is taken.

Calculate the reciprocal of the positive exponent: 2¹⁰.

Since 2¹⁰ is 1024, the reciprocal is 1 divided by 1024.

So, 2 to the -10th power equals 1/1024, which can also be written as 0.0009765625 in decimal form. This concept is crucial for understanding scientific notation, where negative exponents represent small numbers.

The equation that represents this situation is 1.05c + 0.76b = 10.

The equation that represents this situation is option A, which is 1.05c + 0.76b = 10.

To understand why this is the correct equation, let's break it down. The equation represents the total cost of the broccoli and cauliflower Tawny needs to buy. The cost of broccoli is given as $1.05 per pound, so we multiply this cost by the number of pounds of broccoli (b) Tawny wants to buy. Similarly, the cost of cauliflower is given as $0.76 per pound, so we multiply this cost by the number of pounds of cauliflower (c) Tawny wants to buy. The sum of these two costs should be equal to $10, which is Tawny's desired spending amount.
