Step-by-step explanation:

The standard algorithm is a way of doing multiplication by using partial products or multiplying in parts. What you do with this algorithm is multiply the top number by the bottom number one digit at a time, working your way from right to left.

Answer: (6,1)

Step-by-step explanation:

     Coordinate points are written as (x, y).

     Here is a tip for finding coordinate points on a graph:

[1] Start at the origin, point (0, 0) on the graph

[2] "Walk left/right to the elevator" - this is the x-coordinate value

[3] "Go up/down the elevator" - this is the y-coordinate value

     Here is an example, using your problem:

-> See attached

[Points in Blue] Move one unit right, three units up to (1, 3)

[Points in Red] Move two units right, seven units up to (2, 7)

[Points in Green] Move 6 units right, one unit up to (6, 1)

    -> This means the answer to your problem is the third option, (6, 1)

If you are color blind, let me know and I will rephrase it.

Base radius is 5in

Height=8in

Volume

Answer:

Volume = 13.3 in³ (nearest tenth)

Step-by-step explanation:

[tex]\textsf{Volume of a cone}=\sf \dfrac{1}{3} \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

[tex]\textsf{Base area of a cone = area of a circle}=\sf \pi r^2[/tex]

[tex]\implies \textsf{Volume of a cone}=\sf \dfrac{1}{3} h \times \textsf{base area}[/tex]

Given:

Substituting the given values into the formula:

[tex]\begin{aligned}\implies \textsf{Volume of a cone} & =\sf \dfrac{1}{3} (8)(5)\\\\ & = \sf \dfrac{40}{3}\\\\ & = \sf 13.3\:in^3\:(nearest\:tenth)\end{aligned}[/tex]

Answer:

you will have to get a protractor and angle side right

Answer:

xx=-0.8

Step-by-step explanation:

not sure if this is right because the 12xx is kind of strange

12xx+16-1=0
12xx+15=0
12xx=-15
12/12xx=12/-15
xx=-.8

Answer:

a. <B = 53°

b. BC = 14

c. x = 14

Step-by-step explanation:

a. <B = ?

Use Sine.

Sine(<B) = 12 /15

<B = Sin^-1(12/15)

<B = 53.13

<B = 53°

b. BC = ?

Either use Sine(<A) = BC/16 or Cosine(<C) = BC/16

Will be using Cosine.

Cosine(<C) = BC/16

Cosine(30°) = BC/16

BC = 16 * Cos(30°)

BC = 13.856...

BC = 14

c. x = ?

Looking at the triangle. The triangle is isosceles which mean two side angle or side length are the same.

x = 14

Answer:

A: 53.13

B:13.86

C: 14

Step-by-step explanation:

A can be found by using the trigonometric ratio Sin.

Sin=

[tex] \frac{opp}{hyp} [/tex]

And we have our opposite side and hypotenuse. so insert it:

Sin=12/15

Therefore use sin inverse and input that fraction

[tex]sin { }^{ - 1} ( \frac{12}{15} )[/tex]

=53.13010235

Rounded off to two decimals

=53. 13

B can be found using sin again. Since we know that Sin is opp/hyp and we have the hyp, we are now looking for the opp.

So use Sin(60)=BC/16

Multiply 16 on both sides to get: 16Sin(30)=BC

13.85640646=BC

rounded off to two decimals:

13.86

C can be found using Tan. Tan is opp/adjacent

We have the adjacent and we are looking for the opposite.

So use:

tan(45)=X/14

Multiply 14 on both sides

14tan(45)=X

14=X

Hope that helps!

Answer: y = -2x - 4

Step-by-step explanation:

This question asks that you give your answer in slope-intercept form, which is written as y = mx + b, where m is the slope, and b is the y-intercept.

In order to write an equation for this line in slope-intercept form, you need to find the slope and the y-intercept. You can find the slope by selecting any two clear points on the graph and finding the [change in y] ÷ [change in x].

For example, I’ll use (-3, 2) and (-2, 0):

Change in y: 2 - 0 = 2

Change in x: -3 - (-2) = -1

Change in y ÷ Change in x = 2 ÷ (-1) = -2

So, the slope, m, is -2. Finding b, or the y-intercept is a lot more straightforward; you just find where the line intercepts the y-axis, or when x = 0. Looking at the graph, we can see that the y-intercept is -4, so b = -4.

Now, we can put these together in an equation.

y = mx + b, where m = -2 and b = -4

y = -2x -4

Answer:

a = 6

Step-by-step explanation:

Given information:

Slope = 6

Coordinates: (-9, 0) and (-8, a)

Slope formula = y2 - y1 / x2 - x1

Substitute the given values into the formula.

6 = a - 0 / -8 - (-9)

6 = a - 0 / 1

6 = a - 0

a = 6

Answer:

slope = 2.25

Step-by-step explanation:

This equation is written in slope-intercept form, which has the general structure: y = mx + b.

In this form, "m" = slope and "b" = y-intercept.

Therefore, the slope is 2.25 since it is replacing the "m" variable.

[tex]Hello[/tex] [tex]There![/tex]

   We need to find the slope of the line that's parallel to 6x+5y=-5.

It's not hard, I promise! I'm going to take you through a few steps, and we'll find the answer.

Are you ready? Let's start. :)

[tex]Procedure:[/tex]

➢ First, subtract 6x from both sides:

5y=-5-6x

✦ Switch the order of the terms:

5y=-6x-5

➢ Now, divide both sides by 5:

y=-6/5x-5/5

✦ Which is the same as

[tex]\bold{y=-\displaystyle\frac{6}{5} x-1}[/tex]

➢ Part of the problem's already solved! :)

  Now, parallel lines have the same slope.

✦So the slope of the line parallel to 6x+5y=-5 is also:

◉ [tex]\bold{-\displaystyle\frac{6}{5}}[/tex] ☑︎

Problem solved! :)
