Hey guys I need help on this one!!

Answer:

f(x)=[tex]x^{2}[/tex]

Step-by-step explanation:

f(x)=[tex]x^{2}[/tex] may have its domain restricted [0,∞)

under this restriction, f is one-to-one.

Answer:

# 1, 4, & 6

Step-by-step explanation:

you can confirm by checking each number of smiles, boxes, and triangle. because #1 there are 2 triangles and 4 squares. #4 for every triangle there are two squares (4 squares and 2 triangles "split them in half") #6 same thing as #4

It largely depends on required margin of error but I would say that the tested population size is going to be too small.

Answer: 56%

Step-by-step explanation:

There are 750 total people in this crowd.

420 are women and their percentage of the total is needed.

You get this by dividing the number of women by the total number of spectators and then multiplying by 100%:

= Number of women/ Total people * 100%

= 420 / 750 * 100%

= 56%

points are on the graph of the line:-

[tex]\tt{3x+2y=28 }[/tex] ⠀

we get,

[tex]\rightsquigarrow[/tex] [tex]\tt{ 2y=28-3x }[/tex] ⠀

[tex]\rightsquigarrow[/tex] [tex]\tt{y=\dfrac{28-3x}{2} }[/tex] ⠀

In,(0,14)

If we put the value ,x=0

y=[tex]\tt{\dfrac{ 28-3×0}{2}=\dfrac{28}{2}=14 }[/tex]

So,we get one point,(0,14)✔

In,(2,11)

If we put ,x=2

y=[tex]\tt{\dfrac{28-3×2}{2}=\dfrac{28-6}{2}=\dfrac{22}{2}=11 }[/tex]

so,we get another point (2,11)✔

in other given ponts{(1,12),(4,9),(8,4)},It is impossible. ⠀ ⠀

we have to find the line which are in the line!!

points are on the graph of the line:-

we get,

2y=28−3x ⠀

[tex]{y=\dfrac{28-3x}{2} }[/tex]

In,(0,14)

If we put the value ,x=0

[tex]y={\dfrac{ 28-3×0}{2}=\dfrac{28}{2}=14 }[/tex]

so one point is (0,14)

In,(2,11)

If we put ,x=2

[tex]y={\dfrac{28-3×2}{2}=\dfrac{28-6}{2}=\dfrac{22}{2}=11 }[/tex]

so,we get another point (2,11)

in other given ponts{(1,12),(4,9),(8,4)},It is impossible. ⠀ ⠀

Answer:

9^{2}

Step-by-step explanation:

9 x 9 in exponent form is 9², because nine squared is equal to nine times nine.

Answer:

Yes, they have the same solution.

Step-by-step explanation:

Both of these equations have the same solution, just different steps.

To solve Ravi's equation, first we use the distributive property.

2(x+14) = 40

Multiply 2 by x and 14

2x + 28 = 40

Subtract 28 from both sides.

2x + 28 - 28 = 40 - 28

2x = 12

Divide by 2 on both sides.

2x/2 = x

12/2 = 6

so x = 6.

Fran's equation is the same equation as Ravi's second step.

Her equation of 2x + 28 = 40 is Ravi's after distributing 2.

Answer:

2(x+14)=40

2(x+14)=40

÷2         ÷2

x+14=20

 -14  -14

x=6

2x+28=40

   -28       -28

2x=12

÷2  ÷2

x=6

Answer:

Equation of line perpendicular to given graph is:

[tex]y = -\frac{1}{2}x+4[/tex]

Step-by-step explanation:

Given equation of line is:

14x-7y=8

First of all, we have to convert the given equation into slope-intercept form to find the slope of the line

The slope-intercept form is:

[tex]y = mx+b[/tex]

Now

[tex]14x-7y=8\\14x-8 = 7y\\\frac{7y}{7} = \frac{14x-8}{7}\\y = \frac{14}{7}x - \frac{8}{7}\\y = 2x - \frac{8}{7}[/tex]

The co-efficient of x is 2 so the slope of given line is 2

Let m1 be the slope of line perpendicular to given line

The product of slopes of two perpendicular lines is -1

[tex]m.m_1 = -1\\2.m_1 = -1\\m_1 = -\frac{1}{2}[/tex]

The equation for line perpendicular line to given line will be:

[tex]y = m_1x+b\\y = -\frac{1}{2}x+b[/tex]

To find the value of b, putting (-2,5) in the equation

[tex]5 = -\frac{1}{2}(-2) + b\\5 = 1+b\\b = 5-1\\b = 4[/tex]

The final equation is:

[tex]y = -\frac{1}{2}x+4[/tex]

Hence,

Equation of line perpendicular to given graph is:

[tex]y = -\frac{1}{2}x+4[/tex]

Answer:

[tex] \frac{1}{8xy \sqrt{y} } [/tex]

Step-by-step explanation:

[tex](64 {x}^{2} {y}^{3} )^{ - \frac{ 1 }{2} } \\ \\ = \frac{1}{(64 {x}^{2} {y}^{3} )^{\frac{ 1 }{2} } } \\ \\ = \frac{1}{ \sqrt{64 {x}^{2} {y}^{3}} } \\ \\ = \frac{1}{ \sqrt{ {(8xy)}^{2} y} } \\ \\ = \frac{1}{8xy \sqrt{y} } [/tex]

Answer:

.3 recurring as a fraction is 1/3

Answer:

D.)

Step-by-step explanation:

Reflecting an image/shape over the x axis is reflecting it over a horizontal line, so the x coordinates will stay the same and the y coordinates will be the opposite. Therefore, the answer is D. Hope this helps!

Answer: 2:3

Step-by-step explanation:

25/75 beads are square. Thus, 1 out of every 3 beads (1/3) is square. With this information, 2/3 of the beads are round because 1 - 1/3 = 2/3.

This means that the ratio of round to square beads is 2:3.

Answer: 38.34 inches

Step-by-step explanation:

The lamp is round which means that the circumference can be calculated by the formula:

= Pie * diameter

Pie = 22/7

Diameter = 12.2

Circumference = 22/7 * 12.2

= 38.34 inches

Step-by-step explanation:

Step-by-step explanation:

Lets convert each sentence into an algebric inequality.

[tex] = > - 3 \times x = - 3x[/tex]

[tex] = > - 3x \geqslant - 24[/tex]

Lets solve the inequality.

Now , divide -3 on both the sides -

[tex] = > \frac{ - 3x}{-3} \geqslant \frac{ - 24}{ - 3} [/tex]

[tex] = > x \geqslant 8[/tex]

Answer:

[tex](5p - 3) + (2 {p}^{2} - 3p) \\ = 2 {p}^{2} + (5 - 3)p - 3 \\ = 2 {p}^{2} + 2p - 3[/tex]

Answer: the answer is 2p^2+2p−3

Step-by-step explanation:

1. Combine Like Terms: these are 5p and 3p

2. which gives us 2p

3. Always put the squared first and the constant (without any variable last)

which makes 2p^2+2p-3

Answer:

m<ACB = 60°

Step-by-step explanation:

B is a right angle, so its 90°

180-150=30°

180-90=90°

90+30= 120°

180-120= 60°

30+60+90= 180°
