The ball is lower than the bridge at the interval [2, 3.385] and (-∞,0) contains negative values

The equation of the function is given as

h(t)= -16t^2 + 32t + 75

The above equation is a quadratic equation

When the balloon is less than the bridge i.e. a height of 75 feet, we have

h(t) < 75

So, we have the following equation and inequality

h(t)= -16t^2 + 32t + 7

h(t) < 75

Next, we plot the equation and inequality on a graph (see attachment)

The equations intersect at

t = 0 and t = 2

Remove when t = 0

t = 2

The ball hits the ground at t = 3.385

So, the interval is [2, 3.385]

Also, (-∞,0) is not included in the solution because time cannot be negative

3 Answers: x = 0, x = 1, or x = 2

==================================================

Explanation:

The relation

{(0, 5) (1, 5) (2, 6) (x, 7)}

has points with x coordinates of: 0, 1, 2, and x.

If we repeated any of the x values listed so far, then we will not have a function.

So if we had the points (0,5) and (0,7), then the input x = 0 leads to multiple outputs. A function is only possible when any input x leads to exactly one output y.

This means that if x = 0, 1, or 2, then we won't have a function.

Side note: The y values can repeat, but if they do, then we won't have a one-to-one function. In this case, y = 5 repeats, so this function is not one-to-one (assuming x is not 0, not 1, and not 2).

Answer:

Domain is all real numbers.

Range is -3 to infinity that is y >= -3 (that is y -3)

Increasing from x > -4 ( that is from -4 to +infinity) that is to right of -4

Decreasing from x <-4 (that is -infinity to -4) that is to left of -4

This has a minima at x= -4 with y= -3. We can write as (-4, -3)

Maxima is not there as it is going to infinity

  (D)  -1.3 + 1.9

Step-by-step explanation:

The number being subtracted in the given expression is -1.9. The opposite of that number is +1.9.

If we are to show equivalence of subtraction and adding the opposite, we expect to do so with ...

  [tex]-1.3-(-1.9)=\boxed{-1.3+1.9}[/tex]

This is not a choice that is presented in this problem statement, so we suppose it is D (not shown).

Exponential Functions

In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier—it will never be the same, but there will be a pattern.

5 guests

Step-by-step explanation:

Jeremiah party will chat $16 if he invites 4 guest

The first step is to calculate how much it will cost to feed one guest

$4 = 16 guests

1 guest= 16/4

1 guest = $4

Therefore if Jeremiah can afford to spend $20 then the maximum number of people that will be present can be calculated as

$4 = 1 guest

$20= 20/4

= 5 guests

Hence the maximum number of guest is 5 guests

Answer: The missing side is 24 inches

Step-by-step explanation:

Since it is a right angle that  means that we can use the Pythagorean Theorem formula to solve for   the B.

The formula says that  a^2 + b^2 = c^2   Since we know  a is 18 and c is 30 we will input the value into the formula to solve for b.

18^2 + b^2 = 30^2

324 + b^2 = 900

-324               -324

  b^2 = 576

  b = [tex]\sqrt{576}[/tex]  

  b  = 24

Answer:

15 dozens of cakes

Step-by-step explanation:

It is given that Jeanna is making cupcakes for her family and she normally makes 2 dozens of red velvet cakes and 3 dozens of gingerbread spice cakes. But as everybody is staying at home, Jeanna wants to increase the standard amount by 3 for enough cakes.

So,

2 dozens of velvet cakes, i.e.

2 x 12 = 24 red velvet cakes

Increasing this amount by 3 times will give us 24 x 3 = 72 red velvet cakes.

Similarly,

3 dozens of gingerbread spice cakes, i.e.

3 x 12 = 36 gingerbread spice cakes

Increasing this amount by 3 times will give us 36 x 3 = 108 gingerbread spice cakes.

Therefore the total number of cakes is = 72 + 108

                                                                 = 180 cakes.

We know 1 dozen = 12

Therefore dividing 180 cakes by 12, we get

[tex]$=\frac{180}{12}$[/tex]

= 15 dozen cakes.

Therefore, now Jeanna will have to make 15 dozens of cupcakes for all.

Answer:

The value of x is 6

Step-by-step explanation:

The formula of the area of the rectangle is A = l × w, where

In the rectangle ABCD

∵ AB = 2x cm

∴ l = 2x

∵ AD = x cm

∴ w = x

→ Use the formula of the area above to find its area

∵ A = 2x × x

∴ A = 2x²

∵ The area of the shaded region = 50 cm²

→ When the shaded region removed, then the remaining area is the

   unshaded region

∵ The area of unshaded region = 22 cm²

∵ The area the ABCD = area the shaded region + area unshaded region

∴ A = 50 + 22

∴ A = 72 cm²

→ Equate the two right side of A

∵ 2x² = 72

→ Divide both sides by 2

∴ x² = 36

→ Take √  for both sides

∴ x = 6

∴ The value of x is 6

Answer:

It would be C

Step-by-step explanation:

So, shows in the graph, you can see that the change in rise is 100, because to get to 150 from 50, you add 100

And the run is 1, because to go from 0 to 1, you add 1

Meaning the slope is 100/1

Hope this helped!

13. is C.

14. I believe is A.

Sorry if i'm wrong I tried though!
