Answers

Answer:

1/3 would be the y-intercept.

Answer: C. 1/3

A.) 10.9
B.) 8.6
C.) 7.3

Answers

Answer:

Option (c) 7.3

Step-by-step explanation:

Since is forms a right angled traingle,

a= 3+4= 7

b = 4-2= 2

c = AB

Pythagorean theorem:

a^2+b^2 = c^2

So since we know a and B but the hypotenuse (c) is missing

7^2 + 2^2 = c^2

c^2 = 49+4

= 53

c = √53

= 7.28 rounded off to 7.3

So the length of hypotenuse or c is 7.3 units

Therefore, the length is 7.3

Work out the percentage change to 2 decimal places when a price of £189 is decreased to £150.

Answers

Answer:

The percentage change is -21%

Step-by-step explanation:

The percentage change can be expressed by the formula;

(new price -old price)/old price * 100%

New price = £150

old price = £189

Inputing these values in the formula, we have;

(150-189)/189 * 100%

-39/189 * 100%

= -20.63% and that is approximately -21%

1. An arch in the shape of a semicircle is to be set up at the entrance of a festival.
The distance around the arch is about 110 feet. What is the height of the arch, in
feet? Round your answer to the nearest whole number.​

Answers

Answer:

35 ft

Step-by-step explanation:

The arch is in the shape of a semicircle.

The distance around the arch is about 110 feet. This is the same as the circumference of the arch.

The height of the arch is the radius of the arch.

The circumference of a semicircle is given as:

[tex]C = \pi r[/tex]

where r = radius

Therefore:

110 = πr

=> r = 110/π

r = 35.01 ft ≅ 35 ft

The height of the arch is 35 ft

The height of the arch in feet is 35 ft.

Calculation of the height:

Since The distance around the arch is about 110 feet.

We know that

The circumference of a semicircle should be

110 = πr

[tex]r = 110/\pi[/tex]

r = 35.01 ft

≅ 35 ft

hence, we can conclude that The height of the arch in feet is 35 ft.

A candle maker uses a mold to make candles like

The height of the candle is 13 cm and the
circumference of the candle at its widest measure is
31.416 cm. Use modeling to approximate how
much wax, to the nearest cubic centimeter, is
needed to make this candle.

Answers

Answer: 340 cm3  

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:  

Circumference = 2π radius

Replacing with the circumference value and solving for r:

31.416 =2π r

31.416 /2π =r

5cm =r

And then:

Volume of a cone = 1/3 x π x radius^2 x height  

Replacing with the values given:  

V = 1/3 π (5)^2 (13) = 340 cm3

Answers

Answer:

select answers: A), B), C),  D), and E)

Step-by-step explanation:

Please see attached image with the figure obtained by joining the given points.

Notice that the figure is that of a square, and a square happens to be a very special case of a bunch of other figure definitions, like:

rectangle (four side figure with parallel sides and right angles at the vertices) So the square is a special type of rectangle.

Rhombus (four side figure with all sides of the same length) So the square is a special type of rhombus)

Trapezoid (four side figure with at least two parallel sides), So the square is a special type of trapezoid.

Parallelogram (four side figure with two pairs of parallel sides) So the square is a special type of parallelogram.

Therefore you need to select answers: A), B), C),  D), and E)

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

[tex]x_{vertex}= -b/2a[/tex]

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

[tex]f(-13/4)= -9/8[/tex]

Then your expression for this quadratic should be:

[tex]f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})[/tex]

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one

jasmine gets $3.00 every time her song gets 1000 monetized streams. If 3/10 of her streams are monetized how much money would she have if she got 3 million streams?

Answers

Answer:

$270,000

Step-by-step explanation:

1. 3/10 = 30% and 30% of 3,000,000 is equal to 900,000

2. 900,000 divided by 1,000 is 90,000

Then, to calculate the dollar amount we do:

3. 90,000 x 3.00 = 270,000

In step 1, we found 3/10 of her total streams. In step 2, we found how many streams were monetized. And, in step 3 we found the amount of money she made off of those streams.

Summer looked at the formula for the Pythagorean Theorem, a2 + b2 = c2, she said that it didn’t matter which sides of a right triangle were a, b, and c. Is she correct? A. Yes, she is correct. B. No, a must be the shortest side, then b, and c is the longest side. C. No, c must be the shortest side, then b, and a is the longest side. D. No, a and b are interchangable, and c is the longest side.

Answers

Answer: D. No, a and b are interchangeable,  and C is the longest side.

Step-by-step explanation:

Either A and B which are the two legs can be greater than the hypotenuse which is C. They hypotenuse has to always be greater than the two legs and the two legs have the same lengths but it can't be greater than the hypotenuse.  

For example let's say you have a right angle with side lengths  3,4 and 5.

5 in this case has to be always the hypotenuse.

A could be either 3 or 4  but not 5

And  B could also be 3 or 4 but not 5  

because A squared plus B squared is always equal to the hypotenuse which is 5.

3^2 + 4^2 = 5^2

9 + 16 = 25

25 = 25  

Answer:

D. No, a and b are interchangeable,  and C is the longest side.

Need HELP!!!! Write the point-slope form of the line that passes through (5, 5) and is perpendicular to a line with a slope of 1/4. Include all of your work in your final answer.

Answers

Answer:

[tex]y - 5 = -4(x-5)[/tex]

Step-by-step explanation:

Given

Line coordinates: (5,5)

Perpendicular slope = [tex]\frac{1}{4}[/tex]

Required

Find the point slope form of the line

First, the slope of the line has t be calculated;

Given that two lines are perpendicular;

The relationship between there slopes is given as [tex]m_1.m_2 = -1[/tex]

Let m_2 represent the slope of the second line;

such that [tex]m_2 = \frac{1}{4}[/tex]

So;

[tex]m_1 * \frac{1}{4} = -1[/tex]

Multiply both sides by 4

[tex]m_1 * \frac{1}{4} * 4 = -1 * 4[/tex]

[tex]m_1 = -1 * 4[/tex]

[tex]m_1 = -4[/tex]

Now, the equation of the line can be calculated using slope formula;

[tex]m = \frac{y - y_1}{x- x_1}[/tex]

Where

[tex](x_1,y_1) = (5,5)\\m_1 =m = -4[/tex]

So; [tex]m = \frac{y - y_1}{x- x_1}[/tex] becomes

[tex]-4 = \frac{y - 5}{x- 5}[/tex]

Multiply both sides by x - 5

[tex]-4(x-5) = \frac{y - 5}{x- 5} * (x-5)[/tex]

[tex]-4(x-5) = y - 5[/tex]

Reorder

[tex]y - 5 = -4(x-5)[/tex]

Hence, the line in point-slope form is [tex]y - 5 = -4(x-5)[/tex]

A website offers a coupon such that each customer has a 15\%15%15, percent chance of getting the coupon each day they visit the site. Aya visits the website for 666 consecutive days.

Answers

Answer:

0.62

Complete question:

What is the probability that at Aya will be offered a coupon on at least one of the days she visits the website?

Step-by-step explanation:

assuming,

A: Aya gets a coupon one day. P(A) = 0.15

B: Aya doesn't get a coupon one day. P(B) = 1 - 0.15 = 0.85

Aya doesn't get a coupon in any of 6 days  = P(B)^6 = 0.85^6 = 0.38

The probability of Aya getting at least 1 coupon after 6 days is the complement of don't getting any coupon after 6 days, that is:

1 - P(B)^6=  1 - 0.38 = 0.62

Answer:

a

Step-by-step explanation:

The equation of the line that has a slope of 3 and goes through the point (-3,-5) will be y = 3x + 4. Then the correct option is A.

What is the equation of line?

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The slope of the equation is 3. Then the equation of the line is given as,

y = 3x + c

The equation of the line is passing through the point (-3,-5), then the equation of line will be

  y = 3x + c

–5 = 3(–3) + c

–5 = –9 + c

  c = 9 – 5

  c = 4

Then the equation of the line will be

y = 3x + 4

Thus, the equation of the line that has a slope of 3 and goes through the point (-3,-5) will be y = 3x + 4.

Then the correct option is A.
