Answer:

The range of the function are the values of height which are from 3, 4, 5, ..., 50

Step-by-step explanation:

The given parameters are;

The height at which the ball is caught = 5 feet

The height at which the ball was hit = 3 feet

The maximum height reached by the ball = 50 feet

The height of the ball given as a function of time is f(t) s = u·t - 1/2·g·t²

Where;

s = 50 feet

g = 9.81 m/s²

Therefore, we have;

50 = u·t - 1/2 × 9.81 × t²

50 = u·t - 4.905 × t²

Therefore, the range are obtainable values for f(t) which range from 3 to 50.

Answer:

Negative

Step-by-step explanation:

A negative plus a negative (negative minus a positive) will give you a negative. -1.69 + (-1.69) = -3.38

-3.38 is a negative, therefore the answer is negative.

[tex]9=7d+8(9-2d)\\9=7d+72-16d\\9=-9d+72\\-72+9=-9d\\-63=-9d\\d=7[/tex]

Also for the 8(9-2d), simplify by multiplying the 8 into the (9-2d) as we get (8*9)-(8*2d) = 72-16d

Therefore, the answer is d = 7 aka C.

Answer:

k = 5

Step-by-step explanation:

[tex](x + 2)(x + 3) = {x}^{2} + 5x + 6[/tex]

Now comparing left hand side & right hand side ,

[tex] {x}^{2} + kx + 6 = {x}^{2} + 5x + 6[/tex]

Cancelling x^2 & 6 from both left hand side & right hand side ,

kx = 5x

=> k = 5

Answer:  Answer is in the steps

Step-by-step explanation:

To determine if their are congruent ,find the distance between the points.

In AB  it has the points (-6,-4) and (-1,8)  

Now to find the distance you will have to find the difference between the x and y values then square them to add them and find the square root.

-4 - 8 = -12

-6 - (-1) = -5

12^2 + 5^2 =d^2  where d is the distance so solve for d

144 + 25 = d^2

169 =d^2

d = [tex]\sqrt{169}[/tex]  

d= 13  

So we now the distance of AB is 13  

now we need to find the distance between CD

(2,5)  (14,0)  using these points follow the same steps in the first step to find the distance.

5-0= 5

2 -14 = -12

5^2 + 12^2 = d^2

25 + 144 = d^2

169 =d^2

d = [tex]\sqrt{169}[/tex]  

d= 13

So using the information we can say the segments are congruent because they have the same distances .

Answer:

Integer

Step-by-step explanation:

The greatest integer function (as known as the floor function), is defined as to be the greatest integer less than or equal to x.

It is the function:

[tex]f(x)=\floor[x][/tex]

For instance, if x is 2, then f(x) is 2. If x is 2.7, then f(x) is still 2. 2 is the greatest integer less than or equal to 2.

Answer:

Volume = 36.4 m^3 or 9616.6 gallon

weight = 18025.47 N or 80213.33 lbs

Step-by-step explanation:

The complete question is

A small family home in Tucson, Arizona, has a rooftop area of 1967 square feet, and it is possible to capture rain falling on about 56% of the roof. A typical annual rainfall is about 14 inches. If the family wanted to install a tank to capture the rain for an entire year, without using any of it, what would be the required volume of the tank in m3 and in gallons? How much would the water weigh when the tank was full (in N and in lbf)?

The area of the roof = 1967 ft^2

Area of water to be possibly captured = 56% of 1967 ft^2 = 0.56 x 1967 = 1101.52 ft^2

Rainfall depth = 14 inches = 14/12 ft = 1.167 ft

Volume of water = (area of water) x (depth of water) = 1101.52 ft^2 x 1.167 ft = 1285.47 ft^3

35.315 ft^3 = 1 m^3

1285.47 ft^3 = [tex]x[/tex] m^3

==> 1285.47/35.315 = 36.4 m^3

1 ft^3 = 7.481 gallon

1285.47 ft^3 = [tex]x[/tex] gallon

==> 1285.47 x 7.481 = 9616.6 gallon

Weight of water W = ρv

where ρ is the density of water = 62.4 lbs/ft^3

v is the volume of water = 1285.47 ft^3

substituting values,

W = 62.4 x 1285.47 = 80213.33 lbs

but,

1 lb = 4.45 N

therefore,

80213.33 lbs = 80213.33/4.45 = 18025.47 N

If Ali has x cards, then Belinda has 2x cards.

If Ali has x cards, then Charlie has x+5 cards.

2x (Belinda) + x+5 (Charlie) + x (Ali) = 33 (total)

2x + x+5 + x = 33

Now simplify the equation... x+x+5 can be simplified as 2x+5.

2x+5 plus 2x can become 4x+5.

So their total number is 4x+5.

So 4x+5=33.

You want to isolate the variables and numbers.

To remove the 5 from the left side, subtract 5 from both sides.

4x+5-5=4x - 33-5=28

So the equation now is 4x=28

To remove the 4, divide each side by 4.

4x÷4=x - 28÷4=7

So x equals 7, Ali has 7 cards.

Answer:

1) x = 0

2) x = 2

Step-by-step explanation:

1)

12 = -4(-6x - 3)

First, we distribute.

12 = 24x + 12

Then, we combine like terms.

12 - 12 = 24x

0 = 24x

Finally, we divide 24 on both sides.

We got 0 = x, or x = 0

-

2)

-20 = -4x - 6x

First, we simplify.

-20 = -10x

Then, we divide -10 on both sides.

We got 2 = x, or x = 2

The formula used to find the midpoint of a segment with endpoints A(0, 0) and B(m, n) is x = m / 2 and y = n / 2.

What is the midpoint on a given line?

If on a straight line we have two endpoints:

- [tex](x_{1}~,y_{1})[/tex]

- [tex](x_{2},~ y_{2} )[/tex]

and the midpoint is given by ( x, y ).

Then to find the midpoint on a straight line we use the formula:

x = ( [tex]x_{2}[/tex] + [tex]x_{1}[/tex] ) / 2

y = ( [tex]y_{2}+y_{1}[/tex] ) / 2

We have,

[tex](x_{1}~,y_{1})[/tex] = ( 0, 0 )

[tex](x_{2},~ y_{2} )[/tex] = ( m, n )

[tex]x_{1}[/tex] = 0

[tex]x_{2}[/tex] = m

[tex]y_{1}[/tex] = 0

[tex]y_{2}[/tex] = n

We will use the formula :

x = ( [tex]x_{2}[/tex] + [tex]x_{1}[/tex] ) / 2

y = ( [tex]y_{2}+y_{1}[/tex] ) / 2

And substitute the values.

x = ( m + 0 ) / 2

y = ( n + 0 ) / 2

x = m / 2

y = n / 2.

The formula used to find the midpoint of a segment with endpoints A(0, 0) and B(m, n) is x = m / 2 and y = n / 2.

Answer:

Step-by-step explanation:

Factorise

x² - 13x + 42

Consider the factors of the constant term (+ 42) which sum to give the coefficient of the x- term (- 13)

The factors are - 6 and - 7, since

- 6 × - 7 = + 42 and - 6 - 7 = - 13, thus

x² - 13x + 42 = (x - 6)(x - 7)

compare to (x + A)(x + B)

A = - 6, B = - 7

thus 3A - B = 3(- 6) - (- 7) = - 18 + 7 = - 11

The factors may also be expressed as (x - 7)(x - 6)

with A = - 7 and B = - 6, then

3A - B = 3(- 7) - (- 6) = - 21 + 6 = - 15

If the rectangle has sides of Square root 8 and square root 2 which are two irrational numbers but when multiplied it gives an area of 4 square units which is a rational number.

No, it is not possible for a rectangle to have rational side lengths and an irrational area, because two rational numbers are always rational.

Given that,
To figure out, is it possible for a rectangle to have rational side lengths and an irrational area.

Rational numbers can be structured in the form of the fraction of integers. Eg- 5/6, 2/3, etc.

Here,
in a rectangle, two sides have rational length and the area of the rectangle is a product of the sides of the rectangle.
Since there is a property of the rational numbers that, when two rational numbers are multiplied together the product of the rational number is always rational.

So the area of the rectangle also would be rational.

Thus,  it is not possible for a rectangle to have rational side lengths and an irrational area.
