9514 1404 393

Answer:

  yes, 4

Step-by-step explanation:

We assume your sequence is supposed to be ...

  -7, -3, 1, 5

First differences are ...

  -3 -(-7) = 4

  1 -(-3) = 4

  5 -1 = 4

These differences are constant, so we can conclude the sequence is an arithmetic sequence, and the common difference is 4.

Step-by-step explanation:

x= 7/4 - 3/4          

you just have to subtract on variable and then put it on the other side, eventually you will have to divide it all by 4, which you can't do, so it ends up as a fraction:)

To find the average rate of change, we divide the change in the output value by the change in the input value.

Answer:

8 = 2×2×2

[tex]\sqrt[3]{8}[/tex]= ∛2x2x2

    =∛(2)(2)(2)

    =∛2³

    =2

hence ∛8 = 2

2/3 is the slope, rise over ruj

Answer:

slope = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

To find the slope of a line, use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point on the line.

So, this formula requires two points from the line. Reading the graph, we can see that the two points marked on the line are (-3,-4) and (3,0). Thus, use the x and y values of those two points, substitute them in the appropriate order into the formula, and solve:

[tex]\frac{(0)-(-4)}{(3)-(-3)} \\= \frac{0+4}{3+3} \\= \frac{4}{6} \\= \frac{2}{3}[/tex]

Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

Answer:

The area of the rectangle is equal to the base times the height. That is, major side by minor side. In many places we will find how the height is called "h" and the base "b."

Step-by-step explanation:

The dimensions of rectangle are width of 5cm and Length of 28 cm.

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees

The perimeter of rectangle is

Perimeter=2(Length+width)

Given that  length is 3 more than five times its width.

L=3+5W

Perimeter=2(3+5w+w)

Perimeter of rectangle is given by 66cm

66=2(6w+3)

Apply distributive property on RHS side

66=12W+6

Subtract 6 from both sides

60=12W

Divide both sides by 12

W=5

L=3+5(5)=25+3=28

Hence the dimensions of rectangle are width of 5cm and Length of 28 cm.

Answer:

A D AND C

Step-by-step explanation:

Answer:

Step-by-step explanation:

They already said the domain of f(x) is x≥0.

The smallest value of f(x) is f(0) = 9.

Range of f(x) is y≥9.

The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.

The range is y≥0.

Answer:

No, The sum of the lengths of sides b, c must be greater than the length of the remaining side a.

Step-by-step explanation:

b + c ≤ a

you multiply 9.987 x 10 to the power of -13 (10^-13)

your exponent is -13 so first do the exponents after you do that you should get your answer.

Answer:

2.8284

Step-by-step explanation:

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.

Given

[tex]\sqrt{\frac{72}{2} }[/tex]

= [tex]\sqrt{36}[/tex]

= 6

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]

[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]

= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]

= 6

Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.
