Answer:

Where are the graphs?

Step-by-step explanation:

Anyway use this method.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Answer: 60 is the answer.

Step-by-step explanation: We can use the total sum, 180.

To get the missing angle, add the 2 angles, 60 and 60.

60 + 60 = 120.

Then subtract from 180.

180 - 120 = 60.

Hence, 60 is the answer.

Let me know if you have any questions.

cosФ = opp/hyp     sinФ = adj/hyp        hyp = 10      perimeter = a + b + c

for the 45° right triangle

a = b     so      2a² = hyp²                       perimeter 45 = a + a + hyp    

P45 = 2a + hyp         a = sin(45) (hyp)  = [1/2√2)] (hyp)        sin(45) = (√2)/2

P45 = 2([1/2√2)] (hyp) + hyp

P45  = hyp (√2 + 1)

for the 30° right triangle

a = hyp×sin(30)     b = hyp×cos(30)           perimeter 30 = a + b + hyp    

            sin(30) = 1/2       cos(30) = (√3)/2

a  = hyp(1/2)           b = hyp(1/2)(√3)

P30 =        a        +      b         + hyp

        =  hyp(1/2)  +  hyp(1/2)(√3) + hyp

        =  hyp[ 1/2  +  (1/2)√3  + 1]

        =  hyp[ 1/2  +  (1/2)√3  + 1]             factored out the hyp

        =  (1/2)hyp[ 1 + √3 + 2]                  factored out a 1/2

P30  =  (1/2)hyp[ 3 + √3]

which is greater  P45 or P30?   vso I set both perimeters equal to each other

              P45           vs             P30

      hyp (√2 + 1)     =    (1/2)hyp[ 3 + √3]            the hyp cancel

               (√2 + 1)     =    (1/2)[ 3 + √3]                    still tough to tell  needed

               1.414 + 1    =    (1/2)[ 3 + 1.732]                to go to the calsulator

                 2.414      vs    1/2( 4.732)

                 2.414      >     2.366        thus P45 > P30    < -----  Final Answer

b= y-intercept

So, this situation's equation would be y = -32x + 5.

Answer:

m∠1 = 88°

m∠2 = 92°

Step-by-step explanation:

From the given figure lines 'k' and 'm' are the parallel lines and line 'L' is the transversal line,

m∠1 + 92° = 180° [Sum of consecutive exterior angles is 180°]

m∠1 = 180 - 92

m∠1 = 88°

m∠1 + m∠2 = 180° [Linear pair of angles are supplementary angles]

88° + m∠2 = 180°

m∠2 = 180 - 88

m∠2 = 92°

If the height is 4 feet and a base radius is 1 foot of the cylinder. Then the surface area of the cylinder will be 25.13 square feet,

Let r be the radius and h be the height of the cylinder.

Then the surface area of the cylinder will be

SA = 2πrh square units

The height is 4 feet and a base radius is 1 foot of the cylinder.

Then the surface area of the cylinder will be

SA = 2 × π × 1 × 4

SA = 8 × π

SA = 25.13 square feet

Answer:

I believe the two numbers are 14 and 24

Answer:

Those numbers are 14 and 24.

Step-by-step explanation:

You can solve this pretty quickly by taking those two facts and combining them:

a + b = 38

a - b = 10

Let's solve the second one for a:

a = 10 + b

Now we can substitute that into the first one:

a + b = 38

(10 + b) + b = 38

2b + 10 = 38

2b = 28

b = 14

To find a, we can plug that back into one of the original equations:

a + b = 38

a + 14 = 38

a = 24

We can also test our answer by plugging the results into the other given equation and see if we get the same value:

a - b = 10

24 - 14 = 10

10 = 10

So we know our answer is correct.

[tex]\sqrt[7]{3^{2}}[/tex]

Step-by-step explanation:

[tex]3^{2/7}[/tex]

^ That is 3 to the 2/7ths power. We know that. Now it needs to be in radical form. That takes a bit of thinking.

If you have a power that is less than one (like 1/2) it is can be written as a root. So say you're given [tex]2^{1/2}[/tex]. That is the same exact thing as saying [tex]\sqrt{2}[/tex]. It's the same thing. You can say it either way.

In the same way, a squared power, like [tex]2^{2}[/tex], is the same as representing it like a fraction, like [tex]2^{2/1}[/tex]. They both mean the same thing.

So by pointing these out, a fraction power = the power / the root.

If that makes sense.

So, with this in mind, let's look at what we have again.

[tex]3^{2/7}[/tex]

So we can split it up to say that 3 is raised to a 2nd power times a 1/7th power.

So we know what a 3 to the 2nd power is: [tex]3^{2}[/tex].

And since we have a fraction that's also included, we now know that is a root. So we can represent that like this: [tex]\sqrt[7]{3}[/tex].

But those two answers need to be combined. We can do that like this: [tex]\sqrt[7]{3^{2}}[/tex]

Answer: [tex]\sqrt[7]{3^{2}}[/tex]

Answer:

Step-by-step explanation:

The area of the shape is the sum of three sections

1. Rectangle

2. Bigger semicircle

3. Smaller semicircle

Total area:

answer:

157 inches²

step-by-step explanation:

rectangle:

5 X 14 = 70 inches²

big semicircle:

area = πr²

area = (3.14)(7)²

area = 3.14(49)

        = 153.86 inches²

153.86 / 2 = 76.93 inches²

small semicircle:

area = (3.14)(2.5)²

area = 3.14(6.25)

        = 19.625 inches²

19.625 / 2 = 9.8125 inches²

70 inches² + 76.93 inches² + 9.8125 inches²

= 156.7425 inches²

= 157 inches²

Step-by-step explanation:

72° and 3x are adjacent angles and are supplementary , that is

72° + 3x = 180° ( subtract 72° from both sides )
