In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0

Answers

Answer 1

Answer:

Terminal point: (0, 1); sinФ = 1 A

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1

In a unit circle

Ф = 90°

→ By using the 2nd rule above

∴ The terminal point is (0, 1)

sinФ = 1

Terminal point: (0, 1); sinФ = 1

Step-by-step explanation:

The given shape is a pentagon, an irregular polygon, and also convex.

What is a polygon?

A Polygon is considered to be Concave if its diagonal can lie outside the Polygon as well.

A polygon is considered to be Convex if all of its diagonals lie within it.

A polygon is considered to be regular if it is convex and has equal sides and angles.

If all of the angles and sides of a polygon are not equal, it is said to be irregular.

Here,

The given shape has five sides, which means this is a pentagon.

The given shape has unequal sides, which means this is an irregular pentagon.

The given shape has it's all its diagonals lying inside, which means this is a convex pentagon.

Thus, the given shape is a pentagon, an irregular polygon, and also convex.

HELP I GIVE POINTS FOR THIS and brainliest Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11 to determine the 2nd term if f(1) = 4.

Answers

Answer:

The second term is 12.6

Step-by-step explanation:

Let us solve the question

∵ The recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11

f(1) = 4

→ To find the 2nd term, sunstitute n by 2

n = 2

∴ f(2) = 0.4 · f(2 - 1) + 11

f(2) = 0.4 · f(1) + 11

→ Substitute f(1) by 4

∵ f(2) = 0.4 · 4 + 11

→ Simplify the formula

∴ f(2) = 1.6 + 11

f(2) = 12.6

The second term is 12.6

Use the remainder theorem to determine if x = 4 is a zero of the following polynomial and find the quotient and the remainder

Yes, x = 4 is a zero of the polynomial
The quotient is x + 15, and the remainder is 0.
ОВ.
No, x = 4 is not a zero of the polynomial
The quotient is x + 15, and the remainder is 0
OC Yes x = 4 is a zero of the polynomial.

D
No, x = 4 is not a zero of the polynomial.
The quotient is x + 7, and the remainder is -88

Answers

Given:

The polynomial is

[tex]p(x)=x^2+11x-60[/tex]

To find:

Whether x = 4 is a zero of the given polynomial by remainder theorem and find the quotient and remainder.

Solution:

According to the remainder theorem, if (x-c) divides a polynomial p(x), then the remainder is p(c).

Divide the polynomial by (x-4) and check whether the remainder p(x)=0 at x=4.

Putting x=4 in the given polynomial, we get

[tex]p(4)=(4)^2+11(4)-60[/tex]

[tex]p(4)=16+44-60[/tex]

[tex]p(4)=60-60[/tex]

[tex]p(4)=0[/tex]

Since, remainder is 0, therefore, (x-4) is a factor of p(x) and x=4 is a zero.

Now, on dividing p(x) be (x-4) we get

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{x^2+15x-4x-60}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{x(x+15)-4(x+15)}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=\dfrac{(x+15)(x-4)}{x-4}[/tex]

[tex]\dfrac{x^2+11x-60}{x-4}=x+15[/tex]

The quotient is x+15 and remainder is 0.

Therefore, the correct option is A.

Show two methods for finding the quotient :
3/8 divided by 3/4

Answers

Answer:

Here's one :)

3 x 4=  12 =  1

8 x 3=  24 = 2

-by-step explanation:

The two methods of finding the quotient are flipping the divisor and then multiplying and the second one is converting the fractions into decimals and dividing them.

What are fractions?

Fractions describe the part of something present out of the total amount

We know that the result of diving a fraction by a fraction is the same as multiplying that fraction by the reciprocal of the divisor.

∴ (3/8) ÷ (3/4) is,

= (3/8) × (4/3).

= 4/8.

= 1/2.

The second method is converting the fractions into decimals and then dividing them in a conventional way.

3/8 = 0.375 and 3/4 = 0.75.

∴ 0.375 ÷ 0.75 is,

= 0.5.

Find the mode of the following data. 56,34,45,65,67,56,45,36,92,73,92,45,56

Explanation:

Original list = {56,34,45,65,67,56,45,36,92,73,92,45,56}

Sorted list = {34,36,45,45,45,56,56,56,65,67,73,92,92}

We see that 45 and 56 both occur three times each, and this is the most occurring or most frequent. So the mode is the set {45, 56}. It is possible to have more than one mode. It is also possible to not have a mode at all if each value in a list only occurs one time.

How tall is a stack of cube shaped blocks whose volumes are 375 cube inches, 648 cube inches, and 1029 cube inches?

Answer:

The stack of blocks is 25.96 inches tall

Step-by-step explanation:

Volume of a Cube

Suppose we are given a cube of side L, the volume is calculated by:

[tex]V=L^3[/tex]

If the volume is given, the side can be found by solving for L:

[tex]L=\sqrt[3]{L}[/tex]

We know three cube-shaped blocks with volumes 375, 648, and 1029 cube inches. We'll find each of the side lengths and add them up to find the height that results when they stack up vertically.

Block 1, volume =375 cube inches:

[tex]L_1=\sqrt[3]{375}=7.21\ inch[/tex]

Block 2, volume= 648 cube inches:

[tex]L_2=\sqrt[3]{648}=8.65\ inch[/tex]

Block 3, volume =1029 cube inches:

[tex]L_3=\sqrt[3]{1029}=10.10\ inch[/tex]

Total height=[tex]7.21\ inch+8.65\ inch+10.10\ inch=25.96\ inch[/tex]

. The cheetah ran 24.5 meters per second.
. It took the cheetah 5 seconds to run 125 meters.

Answers

Answer:

Step-by-step explanation:

Answers C, D are correct

TBh i really don't know about B because i also think its B but i'm not really that sure but it could be a possibility\

If a cheetah ran 196m is 8 seconds, then 196/8 = 24.5 meters per second.

Let’s verify all answers:

A) 24.5 x 6 = 147. 147m are ran in 6 seconds, not 125.

B) 24.5 x 10 = 245. This answer is correct!

C) We’ve establishes that a Cheetah ran 24.5 meters per second. Correct!

D) Since one minute equals 60 seconds, 24.5 x 60 = 1470. Correct!

E) 24.5 x 5 = 122.5. In this time frame, a cheetah wouldn’t run 125m.

Betty is making a quilt made of various patterns . She buys 3 sheets of fabric that each have an area of 30 square feet. She cuts them up into sections that are each 2/5 of a square foot . How many sections will she have total

Answers

Answer:

She will have 12 sections per fabric and 36 sections in all

Step-by-step explanation:

Betty buy 3 fabrics of 30 ft²

If she cut each to 2/5 of 1 ft²

Then she will have

30 × 2/5

= 6 × 2

= 12

She will have 12 for each fabric and for the 3 fabrics, she will have

12 × 3 = 36

Step-by-step explanation:

Answer:

225 sections

Step-by-step explanation:

Each fabric has an area of 30 sq ft.

All 3 fabrics have a total area of 3 * 30 sq ft = 90 sq ft.

Each sections has an area of 2/5 sq ft.

number of sections = total area of fabric / area of each section

90/(2/5) = 90 * 5/2 = 450/2 = 225

Answer: 225 sections

A meteorologist is measuring the temperature every 15 minutes. She notices the temperature increases by 3/4 degrees Fahrenheit between each measurements for 2 hours. What is the rate per hour of the temperature increase?

Answers

Answer:

3 °F/h

Step-by-step explanation:

The rate per hour of temperature change = change in temperature per measurement/change in time per measurement.

Now, the change in temperature per measurement is constant = 3/4 °F and the change in time per measurement is constant = 15 minutes = 15/60 h = 1/4 h.

So, rate per hour of temperature change = change in temperature per measurement/change in time per measurement

= 3/4 °F ÷ 1/4 h

= 3/4 °F × 4/h

= 3 °F/h

So, the rate per hour of temperature change is 3 °F/h
