Answer:

Step-by-step explanation:

Model of the frog jump is

h = -6t² + 6t

When will the frog be on the ground? The frog will be on the ground at h=0

Therefore,

0 = -6t² + 6t

Divide through by 6

0 = -t² + t

0 = t(-t + 1)

So, t = 0 OR. 0 = -t + 1

So, t = 0. OR. t = 1

So, we should note that, at t = 0, was when he wanted to lift of from the ground... So, t = 0 will be discarded

So, at t = 1 is when the frog is back to the ground.

It is like it starts from the ground at the 0 seconds and get backs to the ground at 1 seconds

Quarterly Rate means the per annum interest rate to be determined for the Bonds on a quarterly basis and the quarterly rate of population increase [tex]0.00447[/tex].

What is quarterly?

If the rate of interest is annual and the interest is compounded quarterly then the number of years [tex](n)[/tex]  is  [tex]4 times[/tex]  and the rate of annual interest [tex](r)[/tex] is one-fourth.

Here given that the annual rate is [tex]r=0.018[/tex].

And the exponential growth function is

[tex]y=a(1+r)^{x} ...(1)[/tex]

where [tex]a[/tex] is the initial amount

and  [tex]r[/tex] is the rate of growth.

So, By equation [tex](1)[/tex], we get

[tex]y=a(1+0.018)^{t}\\y=a(1.018)^{t}[/tex]

The quarterly growth rate, the exponent is the number of quarters in [tex]t years[/tex] or [tex]4t[/tex].

So, by multiplying the exponent by [tex]\frac{4}{4}[/tex], the [tex]4t[/tex] represents the number of quarters

[tex]i.e., y=a(1.018)^\frac{4t}{4}\\y=a(1.018^\frac{1}{4})^{4t}\\y=a(1.00447)^{4t}\\[/tex]

Hence, the quarterly growth rate is [tex]1.00446[/tex], now we subtract it with [tex]1[/tex] so it is of the form:-

[tex]1.004477-1=0.00447[/tex]

which implies that the population is increasing.

[tex]\frac{0.25}{-0.25}[/tex] simplified will give us -1.

It's not a whole number, because it's negative. It isn't irrational because there is a determined answer. While it is rational, it more fits into integer - which is a less broad scope than rational.

Answer: The number of quarters can be 1, 3, 5 or 7

Step-by-step explanation:

Megan has A quarters and B dimes.

The value of a quarter is $0.25 and the value of a dime is $0.10

Then we have that:

A*$0.25 + B*$0.10 = $1.95

We want to know the different possible values of A.

Now, it is usefull to see the different multilpes of 0.25 (this is the odd multyples of 0.25) we only care for the ones that have a 5 in the undredth place, becauses we only can ad multiple of $0.10, so the 5 in the undredth place needs to come from this

Then the possible values of A are the odd numbers such that A*0.25 is smaller than 1.95, let's do the math:

0.25*1 = 0.25 (here 1.95 - 0.25 = 1.70, then B = 1.70/0.10 = 17) the pair is B = 17 and A = 1

0.25*3 = 0.75 (here 1.95 - 75 = 1.20, then B = 1.20/0.10 = 12) the pair is B = 12 and A = 3.

0.25*5 = 1.25 (here 1.95 - 1.25 = 0.70, then B = 0.70/0.10 = 7) the pair is B = 7 and A = 5

0.25*7 = 1.75 (here 1.95 - 1.75 = 0.20, then b = 0.20/0.10 = 2) The pair is B = 2 and A = 7

B) 360 in²

3 rectangles + 2 triangles

(10×12) + (10×13) + (10×5) + 2(½×12×5)

= 120 + 130 + 50 + 60

= 360 in²

The value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.

To evaluate the variable expression for x = 5, we simply substitute 5 for x in the expression.

6.(x- 9) - 5 = 6.(5- 9) - 5

= 6.(-4) - 5

= -24 - 5

= -29

Therefore, the value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.

Given:

A rectangular wall with 2 windows and a 1 door.

To find:

The area of the wall and the amount of paint required to cover the wall.

Solution:

The area of the wall can be determined by subtracting the areas covered by the windows and the door from the area of the entire wall.

The entire wall has a length of 12 feet and a width of 8 feet.

The area of a rectangle [tex]=(l)(w).[/tex]

The area of a square [tex]= a^{2} .[/tex]

The entire wall's area [tex]= (12)(8)= 96[/tex] square feet.

The door has a length of 3 feet and a width of 6 feet.

The area of the door [tex]=(3)(6)=18[/tex] square feet.

The windows are in the shape of a square.

The side length of the windows is 2 feet.

The area of a window [tex]= 2^{2} =4[/tex] square feet.

The area of 2 windows [tex]= 2(4) = 8[/tex] square feet.

The area of the wall [tex]=96-18-8=70[/tex] square feet.

If a quart of extra-thick exterior paint covers 30 square feet, then 70 square feet will need;

The paint needed to cover 70 square feet [tex]= \frac{70}{30} = 2.333[/tex] quarts.

So the area of the wall was 70 square feet and 2.333 quarts of extra-thick exterior paint is required to cover the wall.

Answer:

0.75

Step-by-step explanation:

9/12 equals 3/4 which is 0.75

Answer:

0.75

Step-by-step explanation:

First, you would need to convert it to a fraction for it says "of the", which is one of the key words to a fraction.

In fraction form it would look like this:

9/12

Now, if you remember, fractions are actually division; meaning this problem is also 9 divided by 12. So let's do that!

9 divided by 12 = 0.75.

You can also simplify the fraction; 9/12 is the same as 3/4, and you should know that 3/4 is the same as 0.75

Answer:

36 miles

Step-by-step explanation:

His entire journey, represented with a diagram, is in the shape of a right angle triangle.

We need to first find the hypotenuse of the triangle, then, add all the sides together:

hyp² = opp² + adj²

hyp² = 9² + 12²

hyp² = 81 + 144 = 225

Find the square root of both sides:

hyp = 15 miles

Therefore, adding the three sides together:

Total distance traveled = 9 + 12 + 15

Total distance traveled = 36 miles

He would ride 36 miles altogether.

Answer:

2√7 units.

- (or 5.29 units to the nearest hundredth)

Step-by-step explanation:

If the 2 sides are legs of the triangle ( that is they are at 90 degrees to each other) the third side, by Pythagoras  theorem:

=  √(6^2 + 8^2)

=  √100

= 10 units.

The other possibility is that 8 is the length of the hypotenuse, in which case

The third side

=  √(8^2 - 6^2)

=  √28

= 2√7 units.

Answer:

The area of the rectangular area is (1400w-w²) square yards.

Step-by-step explanation:

Given that,

David has available 2800 yards of fencing. He wants to enclose a rectangular area.

Assume that, the length and width of the rectangular be l and w  respectively.

The perimeter of the rectangular area is

=2(length+ width)

=2(l+w)

So,

2(l+w)= 2800

[tex]\Rightarrow l+w= \frac{2800}{2}[/tex]

[tex]\Rightarrow l+w= 1400[/tex]

[tex]\therefore l= 1400-w[/tex]

The area of the rectangular area is = length× width

                                                            =l×w

                                                           =(1400-w) w

                                                           =(1400w-w²) square yards.

Final answer:

The area A of the rectangle can be expressed as a function of the width W by using the equation 2L + 2W = 2800, where L represents the length of the rectangle. The formula for the area of a rectangle is A = L * W, substituting the value of L in terms of W, we get A = ((2800 - 2W)/2) * W.

Explanation:

To express the area A of the rectangle as a function of the width W, we need to understand that a rectangle has two equal lengths and two equal widths. Let's assume the length of the rectangle is L. Since the perimeter of the rectangle is 2800 yards, we can write the equation: 2L + 2W = 2800.

Now, we can express L in terms of W: L = (2800 - 2W)/2. The area of the rectangle is given by the formula A = L * W. Substituting the value of L, we get A = ((2800 - 2W)/2) * W.

This is the function that expresses the area A as a function of the width W.

Answer:

k = 1

Step-by-step explanation:

English Translation

Find k if the point P (-1, 2k + 1) belongs to the graph of the function f (x) = - 4x^2 + 7.

The function is given as

y = f(x) = -4x² + 7

and point (-1, 2k+1) lies on the graph.

This point means that, at x = -1, y = 2k+1

y = -4x² + 7

Substituting the values in

2k + 1 = -4(-1)² + 7

2k + 1 = -4 + 7 = 3

2k = 3 - 1

2k = 2

k = 1

Hence, the point (-1, 2k+1) is (-1, 3)

To check,

y = -4x² + 7

3 = -4(-1)² + 7

3 = -4 + 7

3 = 3

So, this is truly correct.

Hope this Helps!!!
