Answer 1

Step-by-step explanation:

using cosine rule,

BC²= AC² + BC² - 2*AC*BC*COSc

= 13² + 6² - 2*13*6*-cos(180-91)

= 169 + 36 - (-2.72)

= 202.28

√BC² = √202.28

BC = 14.22

BC = 14.20cm to nearest tenth

What is the value of X

Answers

Answer:

x ≈ 23.31

Step-by-step explanation:

We can use the law of cosines because we know 2 sides and 1 angle.

The general formula  for the law of cosines if the triangle sides are a, b,c and α is the angle between sides a and b. c is the missing side.

[tex]c = \sqrt{a^{2} +b^{2} -2*a*b* cos \alpha }[/tex]

In our problem the law of cosines is

x = [tex]\sqrt{21^{2} +13^{2} - 2*21*13 *cos 83}[/tex]

Answer:

-1/4

Step-by-step explanation:

14x - 2x + 3 = 0
12x + 3 = 0
12x = -3
12x/12 = -3/12
x = -1/4

14x - 2x + 3 = 0

To solve for x move the constant to the other side…
14x - 2x = -3

Since 14x - 2x are the same we can subtract them…
12x = -3

Now we divide 12 by both sides, which looks like this…
12x/12 = -3/13
x = -3/12

Simplify to get…

$8.96

Step-by-step explanation:

Since 6 hot dogs are $6.72, 1 hot dog would be that divided by 6, which is $1.12. Now we want the cost of 8 of those hot dogs, so we have to multiply by 8. Hence the answer is $1.12 * 8 = $8.96.

The probability of an event happening is given as 0.45
What is the probability of the event NOT happening?

Answers

Given:

⇒ Probability of happening of an event = 45%

To Find:

⇒ Probability of event

Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.

⇒ Probability of happening event = 45/100

⇒ Probability of happening event = 0.45

⇒ Probability of non happening event = 55/100

⇒ Probability of non happening event = 0.55

Hence, the correct option is (c) 0.45.

Extra Info:

Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

Jamal would like to purchase a pair of shoes for $80.00. At the store he can spin the spinner below to receive a discount

Answers

John paid $75 for a pair of shoe that cost $100 at a discount of 25 percent.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let us assume that the shoe cost $100, he spins the spinner and gets a discount of 25%, hence:

Money paid = 100 - 25% of 100

Money paid = 100 - 25 = $75

John paid $75 for a pair of shoe that cost $100 at a discount of 25 percent.

Step-by-step explanation:

Because a square has 4 equal sides:

Step 1. Substitute 4x into perimeter equation

Write the equation of the line that passes through the point (2, -1) and has a slope of -3.

Answers

Answer:

Y=-3x+5

Step-by-step explanation:

slope is -3/1

Slope is Rise/Run

meaning 3 down and 1 right

so in this case the down means the Y-axis

and the right means the x-axis

so lets put out some points.

(2,-1)

Then 1 right and down 3

(3, -4)

(4,-7)

and soo on, but we want to fin the point where x is zero.

Why?

Because that is where the y-Intercept is at.

Slope Intercept form is y=mx+b

Where m is the slope

And b is the y- Intercept

Soooo

Let's work backwards

Instead of Right 1 and Down 3 lets do

Left 1 and Up 3

And we will be starting with our original point

(2,-1)

then left 1, Up 3

2-1=1

-1+3=2

soo...

(1,2)

then again

(0,5)

That is our Y-intercept.

Now lets put all of it together.

Y=Mx+B

M=Slope

B=Y-Intercept

Y=-3x+5

A toy car launches off a ramp with a height of 6 feet with an upward velocity of 10 feet per second. The function h = -16t^2 +10t +6 gives the height in feet of the car after t seconds. After how many seconds does the car land on the ground?

Answers

On factoring, the value of t is 1. This shows that the car will land on the ground after 1 sec.

Solving quadratic functions

Quadratic functions are functions having a leading degree of 2.

Given the function height in feet of the car after t seconds expressed as

h = -16t^2 +10t +6

The height of the car on the ground is zero, hence:

16t^2 -10t -6 = 0

8t^2 - 5t - 3 = 0

Factorize the quadratic function

8t^2 - 5t - 3 = 0

On factoring, the value of t is 1. This shows that the car will land on the ground after 1 sec.

A stack of books is 56 inches high. How high is it in feet and inches?

Answers

1 foot = 12 inches


56 inches / 12 inches = 4.66 feet = 4 feet and 8 inches

Answer:

4 feet and 8 inches

Step-by-step explanation:

To convert a high number of inches to feet you divide it by 12 since 12 inches makes 1 foot.

So 56÷12 = 4 reminder 8

The remainder we keep it as inches

So our answer is 4 feet and 8 inches.

Answers

Answer:

b. translation, rotation

Step-by-step explanation:

When a shape is translated, that just means nothing about it has changed except it's location on the coordinate plane. This is that happened with shape 1 - it was translated, and that created shape 2.

When a shape is rotated, that just means it is turned (or rotated) at a specific point. This is what happened to shape 2 that changed it to shape 3.

The other two transformations that aren't shown in this specific example are dilation, which means that the shape either shrinks or grows, and reflection, which means that the shape is reflected across the y-axis or the x-axis.

I included a picture with all four transformation examples in it. I hope this helps! Have a lovely day!! :)

Tracy wants to make a cylindrical model. The height of the cylindrical model, H(V), in inches, is modeled by this

equation, where Vis the volume of the cylindrical model, in cubic inches.

H(V) = 2. 6937

What is the average rate of change of the model's height when its volume changes from 512 cubic inches to

1,000 cubic inches?

The model's height increases by approximately 21. 52 inches for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 022 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 0. 011 inch for every 1-cubic-inch increase in its volume.

The model's height increases by approximately 26. 9 inches for every 1-cubic-inch increase in its volume.

Answers

The average rate of change of the height function is slope of the height function

The model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.

How to determine the average rate of change?

The height function is given as:

[tex]H(V) = 2.69\sqrt[3]{V}[/tex]

When V = 512, the function becomes

[tex]H(512) = 2.69\sqrt[3]{512}[/tex]

[tex]H(512) = 21.52[/tex]

Similarly;

When V = 1000, the function becomes

[tex]H(1000) = 2.69\sqrt[3]{1000}[/tex]

[tex]H(1000) = 26.9[/tex]

The average rate of change is then calculated as:

[tex]H' = \frac{H(1000) - H(512)}{1000 - 512}[/tex]

This gives

[tex]H' = \frac{26.9 - 21.52}{1000 - 512}[/tex]

[tex]H' = \frac{5.38}{488}[/tex]

Evaluate the quotient

[tex]H' = 0.01102459016[/tex]

Approximate

[tex]H' = 0.011[/tex]

Hence, the model's height increases by approximately 0.011 inch for every 1-cubic-inch increase in its volume.
