Answer:

(24,4,84)

Step-by-step explanation:

Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.

[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]

[tex]5(4) + 4 = 24[/tex]

[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]

[tex]5(4) {}^{2} + 4 = 84[/tex]

So our range is (24,4,84)

Answer:

f(x)=5x²+4

f(-2)=5×(-2)²+4

f(0)=5(0)²+4

f(4)=5×(4)²+4

so the range of function{-2,0,4}is{24,4,85}

Answer:

x=8.332451

Step-by-step explanation:

SOH CAH TOA

Tan(48) = 10/x

1.200127 = 10/x

1.200127x = 10

x=8.332451

Answer:

x = 112

y = 76

Step-by-step explanation:

x + 68 = 180

x = 180 - 68

x = 112

y = 76 (Because of alternate interior angles)

Answer:

Step-by-step explanation:

From the dot plot of start of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 5

Range of the data set = 10 - 5

                                    = 5 miles

From the dot plot of End of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 6

Range of the data set = 10 - 6

                                    = 4 miles

The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

Answer:

D

Step-by-step explanation:

The answer is D because A and B is an alternate interior angle meaning they don't have to be parallel lines in order to show that they are the same angles. C is incorrect.

E is incorrect because perpendicular lines mean that they have to be 90 degrees angle but the one that is shown is diagonal instead.

If we can show ∠4 ≅ ∠8 then EH || FG. [option A]

Two lines are said to be parallel if they do not meet each or intersect each other and have same slope.

Given is a quadrilateral EFGH, we need to determine a reason that can show EH || FG.

So, we know if two alternate angles between two lines are equal then the lines will be parallel by converse of alternate angles theorem.

Here, ∠4 and ∠8 are alternate angles, so if we show that ∠4 ≅ ∠8 then we can conclude that EH || FG.

Hence the correct option is A.

Answer:

20%

Step-by-step explanation:

5 20% = 100%

Answer:

20% is 5$.

Step-by-step explanation:

Ok - these always need a bit of a read to make sure we're answering the right thing.

"What percent..." asks us for a percentage. Ok - good.

"...of 25..." asks us to take the number (25) and multiply it by the percentage we're going to find.

"...is 5" tells us what the answer we're looking for is. So we have:

25  ×  P  =  5

- 25 times some percentage equals 5.

We can treat P as a variable and so can divide both sides by 25:

p = 5/25 = 1/5 = 0.2 = 20%.

Step-by-step explanation:

Answer:

x= -4, y= -7

Step-by-step explanation:

First, label the 2 equations.

6x -5y= 11 -----(1)

y= 7x +21 -----(2)

Substitute (2) into (1) so that the first equation is only written in terms of x.

6x -5(7x +21)= 11

6x -5(7x) -5(21)= 11 (Expand)

6x -35x -105= 11

-29x= 11 +105 (Simplify, +105 on both sides)

-29x= 116

x= 116 ÷(-29)

x= -4

Substitute x= -4 into (2):

y= 7(-4) +21

y= -28 +21

y= -7

Answer: 75ml

Step-by-step explanation:

The volume of a rectangular prism is:

= Length × width × height

where,

Volume = 22500ml³

Length = Unknown

Width = 50ml

Height = 6ml

We then slot the values into the formula.

Volume = Length × width × height

22500 = Length × 50 × 6

22500 = Length × 300

Length = 22500/300

Length = 75ml

The length of the cellular phone is 75ml.
