Answer:

[tex]1156.8cm^3[/tex]

Step-by-step explanation:

The volume of a cone is given as:

[tex]V =\frac{1}{3} \pi r^2h[/tex]

where r = radius

h = height of cone

The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).

Its volume is:

[tex]V = \frac{1}{3} * \pi = 7.9^2 * 17.7\\ \\V = 1156.8cm^3[/tex]

Answer:

1157.3cm^3

Step-by-step explanation:

voume of a cone =V=πr^2h^3

Diameter = 15.8cm

Height = 17.7cm

Radius = diameter/2

= 15.8/2 = 7.9cm

Pi = 22/7

V = 22/7 ×7.9×7.9×17.7/3

= 22/7×62.41×5.9

V = 1157.25cm^3

Hence the volume of the cone is 1157.3cm^3

Answer:

Domain is x ∈ R

Step-by-step explanation:

There weren't any options given, but for f(x) = 2x + 15, the domain is x ∈ R.

This is because the graph is a linear function, which exists for all values of x. You can express this in lots of different ways, but R (all reals) is the conventional way to do it.

In case you don't know what a domain is: it is a set of numbers that the x-values of an equation can fit into.

Example:

f(x) = [tex]x^{2}[/tex] -> x ∈ R

This is because, if you draw a quadratic graph, you can see that the values of x are neverending.

Answer:

[tex]y=x+2[/tex]

Step-by-step explanation:

We are given the points (-2,0) and (0,2).

Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-0}{0-(-2)}=\frac{2}{2} = 1[/tex]

The slope is one.

So far we have [tex]y=x+b[/tex].

We can use a point to find 'b', the y-intercept.

I will use (0,2):

[tex]2=0+b\\2-0=0-0+b\leftarrow \text {Subtraction Property of Equality} \\\boxed {2=b}[/tex]

The y-intercept is 2.

The equation of the line is [tex]y=x+2[/tex].

In slope equations, the 'one' is commonly hidden.

Answer:

y = x + 2

Answer: 5 and 7

Step-by-step explanation:

Answer:

ellis

Step-by-step explanation:

The student who graphed a linear function with a y-intercept at -4 is Ellis.

Option C is the correct answer.

We have,

The student who graphed a linear function with a y-intercept at -4 is Ellis.

Looking at the given information, Ellis's line goes through points (0, -4) and (2, 0).

The y-coordinate of the y-intercept is -4, which matches the requirement.

Therefore, Ellis is the student who graphed a linear function with a y-intercept at -4.

Thus,

The student who graphed a linear function with a y-intercept at -4 is Ellis.

The remainder of the equation A = 22,714 / 886 is given by R = 564

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the remainder be represented as R

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 22,714

Let the second number be q = 886

Now , A = p/q

On simplifying , we get

A = 22,714 / 886

886 x 25 = 22150

So , the difference between 22714 - 22150 = 564

Therefore , the value of R is 564

Hence , the remainder is 564

x = -14

Step-by-step explanation:

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

multiply 2 on both sides

the 2's cancel out on the fraction side, leaving x = -7(2)

multiply -7 and 2 to get -14

x = -14

Answer:

-14

Step-by-step explanation:

We must find out what divided by 2 equals -7

So we work backwards

2(-7)

2(-7)=-14

When multiplying negative and positive you get negative

Plug in -14 in x

-14/2=-7

Answer:

[tex] \boxed{c = -17} [/tex]

Step-by-step explanation:

[tex] = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17[/tex]

Answer:

c = -17

Step-by-step explanation:

→Distribute the 7 to (-7c - 19):

3 - 7c - 20c = -49c - 133 + 14c

→Add like terms (-7c and -20c, -49c and 14c):

3 - 27c = -35c - 133

→Add 35c to both sides:

3 + 8c = -133

→Subtract 3 from both sides:

8c = -136

→Divide both sides by 8:

c = -17
