Answer:

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

We have the equation:

[tex](x-6)^2+(y-7)^2=25[/tex]

h = 6, k = 7, r = √25 = 5

The diameter d = 2r → d = 2(5) = 10

all i can say is the square root of 17 is 4.1 thats all i know

Answer:

C

Step-by-step explanation:

Use the distance formula.

We have the points (0,0) and (8,sqrt17)

This basically means sqrt(8^2+sqrt(17)^2)

Which amounts to

sqrt(64+17)

Which is

sqrt(81)

Which is 9.

Answer:

Surface area = 207.24 in²

Step-by-step explanation:

Remember to always convert the diameter into a radius.

D = 6 in (divide it by two to get the radius) R = 3 in

Radius = 3 in

Formula:

SA = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

Solution:

SA = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

SA = 2(3.14)(3)(8) + 2(3.14)(3)

SA = 2(3.14)(3)(8) + 2(3.14)(9)

SA = 150.72 + 56.52

SA = 207.24 in²

Answer:

[tex]2x^{4}+x^{3}-x+2[/tex]

Step-by-step explanation:

To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.

[tex]x^{3}+3x^{2}-2x-6[/tex]

[tex]x^{3}+3x^{2}[/tex]and[tex]-2x-6[/tex]

[tex]x^{2}(x+3)[/tex]and[tex]-2(x+3)[/tex]

So this one is not prime, since you can still factor it.

[tex]x^{3}+2x^{2}-3x-6[/tex]

[tex]x^{3}+2x^{2}[/tex]and[tex]-3x-6[/tex]

[tex]x^{2}(x-2)[/tex]and[tex]3(x-2)[/tex]

So this one is not prime, since you can still factor it.

[tex]4x^{4}+4x^{2}-2x-2[/tex]

[tex]4x^{4}+4x^{2}[/tex]and[tex]-2x-2[/tex]

[tex]4x^{3}(x+1)[/tex]and[tex]-2(x+1)[/tex]

So this one is not prime, since you can still factor it.

[tex]2x^{4}+x^{3}-x+2[/tex]

[tex]2x^{4}+x^{3}[/tex]and[tex]-x+2[/tex]

[tex]x^{3}(2x+1)[/tex]and -x+2 cannot be further factored.

Therefore, [tex]2x^{4}+x^{3}-x+2[/tex] is a prime.

Answer:

Step-by-step explanation:

The formula of a distance between two points:

We have the points (5, 4) and (-3, -1). Substitute:

[tex]d=\sqrt{(-3-5)^2+(-1-4)^2}=\sqrt{(-8)^2+(-5)^2}=\sqrt{64+25}=\sqrt{89}\approx9.43[/tex]

Answer:

143.79

Step-by-step explanation:

The area of the figure can be found by splitting it into two shapes - a semi circle and a trapezoid.

The area of a semi-circle is found using A = 1/2πr² where r = 4.5 since the diameter is 9. A = 1/2π(4.5)² = 31.79.

The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(23 + 9)(7) = 112.

Together the area is 31.79 + 112 = 143.79.

Answer:

9c

Step-by-step explanation:

Collecting like terms

We can do 8-6 which is 2

and then 2 add 7 which is 9

Add c

Answer:

A = 10.5 units^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2(b1+b2) *h

b1 = 5

b2 = 2

h = 3

I found these by looking at the graph

A = 1/2(5+2) *3

A =1/2(7)3

A = 10.5 units^2

Check the picture below.

so then, let's notice, this triangular prism is really just 2 triangles and 3 rectangles stacked up to each other at the edges.

so if we simply get the area of each of those figures, and sum them up, that'd be the area of the prism.

notice, the triangles have a base of 4 and a height/altitude of 3.

[tex]\bf \stackrel{\textit{2 triangles}}{2\left[ \cfrac{1}{2}(4)(3) \right]}~~+~~\stackrel{\textit{inclined rectangle}}{(5\cdot 11)}~~+~~\stackrel{\textit{ground rectangle}}{(4\cdot 11)}~~+~~\stackrel{\textit{standing rectangle}}{(3\cdot 11)} \\\\\\ 12+55+44+33\implies 67+77\implies 144[/tex]

Answer:

B

Step-by-step explanation:

if a is greater then b and b=7 and A< 8  7.5 is the only one that fits the description

Option B) a = 7.5 is the correct

The question is asking which option is a counterexample to the assertion that if a and b are real numbers with a > b and b = 7, then a ">=_" 8. To find a counterexample, we need an instance where a is greater than b (which is 7), but a is not greater than or equal to 8.

A) a=6.5 cannot be the correct answer because it is not greater than b. B) a = 7.5 is indeed greater than b=7, but it is less than 8 which makes it the correct counterexample. Both C) a= -8.5 and D) a=8.1 are not counterexamples; the former is less than b, and the latter is greater than 8.

Therefore, option B) a = 7.5 is the correct counterexample because it satisfies the condition a > 7 but does not meet the incorrect assertion that a is also ">=_" 8.

A statistical question has to be a question that can be answered by collecting data that varies.

Answer:

B.   What are the shoe sizes of players on the soccer team?

Step-by-step explanation:

A statistical question is one that can be answered by collecting data and where that data will vary.

We do not need to collect data to determine the number of questions on Ben's math test.

There is no variability in the number of chocolates Bertha sells in one day, nor in the number of students in Kathy's class.

To determine the shoe sizes of players on the soccer team, we must collect the data and the data will vary from player to player.  This is the statistical question.

Answer:

You can use 1 as a solution.

Step-by-step explanation:

10 + 1 = 11

1 * 4 = 4

4 - 2 = 2

11 > 2

Mean = Sum of all data divided by number of data

= (6 + 14 + 10 + 6 + 4 + 8) / 6 = 8. (C)

The required mean value fo the given data is 8. Option C is correct.

Given that,
Vanilla-6 Chocolate-14 Strawberry-10 Butter Pecan-6 Cookie Dough-4 Moose Tracks-8,
mean value of the given data is to be determined.

The mean of the values is the ratio of the total sum of values to the number of values.

Statistic is the study of mathematics that deal with relations between comprehensive data.

Here,
Number of values = 6
Mean  = sum of the values/number of values
mean = [6 + 14 + 10 + 6 + 4 + 8]/6
Mean = 48 / 6
Mean = 8

Thus, the required mean value fo the given data is 8. Option C is correct.

Answer: (0,0)

Step-by-step explanation:

To find the scale factor of coordinates, you have to multiply the x and y by the scale factor, which is 3.

0 × 3 = 3

0 × 3 = 3

Answer is (0,0)

The rule would be : (x, y) --> (3x, 3y).

The coordinate rule for a dilation centered at (0,0) with a scale factor of 3 is (x', y') = (3x, 3y).

A dilation is a transformation that changes the size of a figure without altering its shape. The coordinate rule for a dilation centered at (0,0) with a scale factor of 3 is given by the equation:

(x', y') = (3x, 3y)

This means that each coordinate of the original figure is multiplied by the scale factor to find the corresponding coordinate of the dilated figure.

Answer:

2/3

Step-by-step explanation:

Given in the question two points

(84,80) and (74,65)

Here

x1 = 84

x2 = 74

y1 = 80

y2 = 65

Slope of line means gradient of line and formula to calculate gradient of line is

gradient = [tex]\frac{x2-x1}{y2-y1}[/tex]

plug values in the formula

[tex]\frac{74-84}{65-80}[/tex]

[tex]\frac{-10}{-15}[/tex]

cancel - sign

[tex]\frac{10}{15}[/tex]

2/3 is the gradient of line having coordinates (84,80) and (74,65)

Answer:

40

Step-by-step explanation:

This is essentially just (4/3), or [tex]\frac{3}{4}^{-1}[/tex]. (4/3)*30 = 40, so our answer must be 40. Just to check, taking 75 percent of 40, we indeed get 30!

For this case we must find a number of which 30 represents 75%. For this, we make a rule of three:

x ------------> 100%

30 ----------> 75%

Where the variable "x" determines the base number of which 30 is 75%

[tex]x = \frac {100 * 30} {75}\\\\[/tex]

[tex]x=40[/tex]

Thus, 30 represents 75% of 40.
