Answer: h(t)=[tex]16x^{2} \\\\[/tex]+80t+4

Step-by-step explanation:

80 if feet per second so it's 80*seconds where seconds equals t

this gets you 80*t or 80t.

You need to add 4 because that's the initial height to start with so 16x^2+80t+4

Answer:

3

Step-by-step explanation:

We have been given a function as; f(x)= -3x+3. then it is found that f(0) =  3

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given a function as;

f(x)= -3x+3.

then we need to find the function when x is equal to zero.

If f(x) = -3x + 3, this means that any number that replaces x in the parenthesis, would replace x in the right side too.

When x = 0:

f(0) = -3(0) + 3 = 3

f(0) =  3

Therefore, We have been given a function as; f(x)= -3x+3. then it is found that f(0) =  3

Answer:

the number is 4

Step-by-step explanation:

let the number be x

2x + 10 = 6(x - 1)

2x + 10 = 6x - 6

minus both sides by 2x

10 = 4x - 6

add both sides by 6

4x = 16

x = 4

Answer:

(7, 3)

Step-by-step explanation:

If we reflect a point/figure across the y-axis, the rule is (x, y) -> (-x, y).  

Now, let's reflect it against the y-axis again.

As you can see, we're back to where we started- at (7, 3). Thus, we can conclude that reflecting across the y-axis twice will result in the original point/figure.

Answer:

Step-by-step explanation:

Note:

Circumference of a circle = [tex]\pi d[/tex]

Where d = diameter

We are given the diameter is 20cm, d = 20

Circumference of circle = [tex]\pi d[/tex] = 20 [tex]\pi[/tex]

Also, perimeter of a rectangle = 2 times length + 2 times width

We are told the length = 18 , width = x

Perimeter of rectangle = 2 times 18 + 2 times x

Perimeter of rectangle = 36 + 2x

The question also tells us that the circumference of the circle is EQUAL to the perimeter of the rectangle:

So this means:

Since Circumference of circle = 20[tex]\pi[/tex]  ,

Perimeter of rectangle = 36 + 2x .

We can write:

Circumference of circle = perimeter of rectangle

20[tex]\pi[/tex]   = 36 + 2x

Subtract 36 from both sides

20[tex]\pi[/tex] - 36   = 2x

Divide both sides by 2 to solve for "x".

x = [tex]\frac{20\pi - 36 }{2} = ?[/tex]

Plug it into your calculator and then just round it to 1 decimal place.

A possible practical domain for the function is T > 12500

The domain are the input values for which a function exist.

Given the function relating the metal bar is L cm long when its temperature is T◦C as:

L(T) = 0.002T + 25

The domain of the expression is the point where 0.002T + 25 is greater than zero.

0.002T + 25 > 0

0.002T > -25
T > 12,500
