Answer:

Correct answer: y= 4 cos 2theta

Step-by-step explanation:

The Cosine Function

The general form of the cosine is

[tex]Y=A.cos(w\theta+B)[/tex]

where A is the amplitude, w is the angular frequency and B is the phase shift

The amplitude is the positive top value of the sinusoid or the most negative value. Since the sinusoid goes from -4 to 4, the amplitude is 4, thus

[tex]Y=4cos(w\theta+B)[/tex]

To find B and w, we use two points from the graph (0,4) and [tex](\pi/4,0)[/tex]:

[tex]4=4cos(w\times0+B)[/tex]

Simplifying

[tex]1=cosB[/tex]

Thus B=0

Now for the second point

[tex]0=4cos(w\times \pi/4)[/tex]

Or equivalently

[tex]\displaystyle \frac{\pi w}{4}=\frac{\pi}{2}[/tex]

Thus

w=2

Then, the cosine function is

[tex]Y=4cos2\theta[/tex]

Correct answer: y= 4 cos 2theta

Answer: 36 degrees

Step-by-step explanation:

The angle a is 63 degrees because 177 and a are supplementary and equal 180 degrees. Because there are 180 degrees in a triangle, 63+ 81 is 144. 36 and 144 is 180, therefore b is equal to 36.

Hope this helped!

An exterior angle of a triangle equals the sum of its opposite interiors.

The measure of b is 36 degrees

To calculate angle b, we use the following equation

[tex]b + 81 = 117[/tex] ------- because b and 81 are opposite interior angles to 117

Solving further, we have:

[tex]b = 117 - 81[/tex]

Evaluate like terms

[tex]b = 36^o[/tex]

Hence, the measure of b is 36 degrees

Answer:

7 gallons of gas

Step-by-step explanation:

because the car can drive 53 miles on 1 gallon and your trying to find the amount of gallons needed for 371 miles you would divide 371 by 53 and you get 7.

Final answer:

To find out how many gallons of gas are used to drive 371 miles in a hybrid car with a fuel economy of 53 miles per gallon, divide 371 by 53, resulting in 7 gallons of gas needed.

Explanation:

To determine how many gallons of gas a hybrid car will use to drive a total of 371 city miles when the car can drive 53 miles on 1 gallon of gas, you can set up a simple division problem. The formula to calculate gallons used is:

Total miles driven ÷ Miles per gallon = Gallons of gas used

In this case, we divide 371 miles by 53 miles per gallon to find the total gallons of gas used:

371 miles ÷ 53 miles/gallon = 7 gallons

So, the hybrid car will use 7 gallons of gas to drive 371 city miles.

Answer:

301.44 feet.

Step-by-step explanation:

Given: Distance between the girl and the center of the carousel is 8 feet.

            Girl stands in a carousel and rotates around the ride 6 times.

We know the radius if carousel is 8 feet.

Now, finding the circumference of carousel to find the area covered in one rotation of carousel.

Circumference= [tex]2\pi r[/tex]

⇒ Circumference= [tex]2\pi \times 8[/tex]

∴ Circumference= [tex]16\pi[/tex]

As given, carousel rotated 6 times.

Length covered in 6 rotation of carousel= [tex]6\times 16\pi[/tex]

⇒ Length covered in 6 rotation of carousel= [tex]96\pi[/tex]

Taking, π = 3.14

⇒ Length covered in 6 rotation of carousel= [tex]96\times 3.14[/tex]

∴Length covered in 6 rotation of carousel= [tex]301.44\ feet[/tex]

Hence, 301.44 feet travelled by little girl in a Carousel.

The little girl traveled approximately 301.62 feet.

To find the distance the little girl traveled on the carousel, we need to calculate the circumference of the circle and then multiply by the number of rotations.

The formula for the circumference of a circle is:

C = 2 × π × r

where r is the radius. Here, the radius r is 8 feet.

C = 2 × π × 8

C = 16π

So, the circumference is approximately 50.27 feet (since π ≈ 3.14).

Since the girl rotates around the carousel 6 times:

Total Distance = Number of Rotations × Circumference

Total Distance = 6 × 50.27

Total Distance ≈ 301.62 feet

Therefore, the little girl traveled approximately 301.62 feet.

To multiply fractions, you multiply numerator with numerator and denominator with denominator

In other words: a/b*c/d=(a*c)/(b*d)

So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified

2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified

3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified

4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number

[tex]R=5N+7[/tex]

[tex]\displaystyle N=\frac{R-7}{5}[/tex]

Step-by-step explanation:

Equations

The relation between the number thought by Ann (N) and the final result (R) can be expressed as

[tex]R=5N+7[/tex]

So if for example, Ann thought in the number N=12, then  

[tex]R=5\times 12+7=67[/tex]

If we know the value of R, it's easy to find back the value of N by solving the equation

[tex]R=5N+7[/tex]

subtracting 7 on each side

[tex]R-7=5N[/tex]

Dividing by 5

[tex]\displaystyle N=\frac{R-7}{5}[/tex]

So, if Ann tells Jim that R = 52, he can guess her number is

[tex]\displaystyle N=\frac{52-7}{5}[/tex]

[tex]N=9[/tex]

The formula for r, the value Jim hears, for any given value of n (Ann's number) is: r = 5n + 7

This formula breaks down as follows:

5n: This represents Ann multiplying n by 5.

+ 7: This represents Ann adding 7 to the result of multiplying n by 5.

r: This represents the final value, which Jim hears.

Therefore, by plugging any value of n into this formula, you can calculate the value of r that Jim would hear.

To find the selling price of the wallet after a 60% markup and a profit of $15, we need to calculate the original price of the wallet and add the profit to it. The original price of the wallet is $25 and the selling price is $40.

To find the selling price of the wallet, we need to first find the original price of the wallet before the markup. Let's call the original price 'x'. Given that the store makes a profit of $15 on a wallet after a markup of 60%, we can write the equation:

x + 0.6x = x + $15

Simplifying the equation, we get:

1.6x = x + $15

0.6x = $15

x = $15 / 0.6

So, the original price of the wallet is $25.

The selling price of the wallet is the original price plus the profit, which is $25 + $15 = $40.

Answer:

The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Amount of fliers the volunteers gave for a political campaign = 21/38

Remaining 612 were given out in another neighborhood

2. What is the total number of fliers they gave out?

x = Total of fliers

21x/38 = Fliers given out in the first neighborhood

612 = Fliers given out in the second neighborhood

Let's solve for x, this way:

x - 21x/38 = 612

38x - 21x = 612 * 38 (38 is the Lowest Common Denominator)

17x = 23,256

x = 23,256/17

x = 1,368

The total number of fliers the volunteers gave out is 1,368: 756 in the first neighborhood and 612 in the second.

           [tex]\large\boxed{\large\boxed{100}}[/tex]

Explanation:

This question comes with four answer choices:

You just need to find a rough estimate of the volume of the jar and the volume of one jelly bean. This is called magnitude order.

The jellybean jar is cylindrical, Thus, its volume is [tex]\pi \times radius^2\times height[/tex]

To find the order of magnitude, you just use the numbers rounded to one signficant figure: round π to 3, the radius to 5, cm, and the height to 10:

            [tex]Volume\approx 3cm\times (5cm)^2\times10cm=750cm^3\approx1,000cm^3[/tex]

The order of magnitude for the radius of a jellybean is 1 cm. And the order of magnitude of the volume of a sphere with a radius of 1 cm is the cube of the diameter (2cm):

             [tex](2cm)^3=8cm^3\approx10cm^3[/tex]

Hence, a reasonable lower limit for the number of jellybeans in the jar is:

                     [tex]1,000cm^3/10cm^3=100[/tex]

To find a reasonable lower limit for the number of jelly beans in a jar with a radius of 4.8 cm and height of 11.8 cm, you can calculate the volume of the jar to be approximately 272 cm^3. Assuming the volume of a jelly bean to be approximately 1 cm^3, you can estimate the jar might hold at least 272 jelly beans.

To calculate a reasonable lower limit for the number of jelly beans in the jar, a good starting point could be to calculate the volume of the jar and then consider the volume of a single jelly bean. Let's assume a jelly bean has an approximate volume of 1 cm^3 (though they can be bigger or smaller).

Given that the jar is cylindrical, we can calculate its volume using the formula for the volume of a cylinder: πr^2h, where r is the radius and h is the height. Here, radius = 4.8 cm and height = 11.8 cm.

Applying the values, we have: volume = π(4.8)^2 *11.8 = ~271.64 cm^3.

Dividing this volume by the volume of a single jelly bean gives us a rough estimate of the number of jelly beans that can fit in the jar. So, 271.64 cm^3 /1 cm^3 = 271.64, so roughly 272 jelly beans could be a reasonable lower limit, but you might be able to fit more depending on their actual size and how tightly they can pack together.

Answer:

2300

Step-by-step explanation:

The answer is 2300: first we need to know what we need to round the answer up to, because we need to round it up to hundred, we need to look at the number in the unit below it. So because we need it to the nearest hundred we look at the number in the tens. If the number is 0-4 we round down, if the number is between 5-9 we round up, because the number is 4 we round 2342 down to 2300. When we round down the number stays the same, if we round up we increase the number by 1. So the answer is 2300.

Slope-intercept form:  y = mx + b

[m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]

For lines to be perpendicular, their slopes have to be negative reciprocals of each other. [basically changing the sign (+/-) and flipping the fraction/or switching the numerator and the denominator]

For example:

m = 2 or [tex]\frac{2}{1}[/tex]

Perpendicular line's slope = [tex]-\frac{1}{2}[/tex]

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

Perpendicular line's slope = [tex]\frac{4}{1}[/tex] or 4

Since you know the slope of the line is:

y = -3/4x + 5

m = [tex]-\frac{3}{4}[/tex]      

The perpendicular line's slope is [tex]\frac{4}{3}[/tex], so plug it into the equation

y = mx + b

[tex]y=\frac{4}{3} x+b[/tex]        To find b, plug in the point (-3, -3) into the equation

[tex]-3=\frac{4}{3} (-3)+b[/tex]

-3 = -4 + b   Add 4 on both sides to get "b" by itself

1 = b

The y-intercept is 1
