Answer:

The real zero is between 1 and 2.

Step-by-step explanation:

The given function is:

[tex]f(x)=x^3-2[/tex]

To find the zeros of this function, we set f(x)=0.

[tex]\implies x^3-2=0[/tex]

Add 2 to both sides to obtain:

[tex]\implies x^3=2[/tex]

Take the cube root of both sides

[tex]\implies x=\sqrt[3]{2}[/tex]

[tex]\implies x=1.26[/tex]

Therefore the real zero is between 1 and 2.

Answer:

57%

Step-by-step explanation:

We are given the results of survey of one thousand families to determine the distribution of families by their size.

We are to find the probability (to the near percent) that a given family has 3, 4 or 5 people.

Frequency of families with 3, 4 or 5 people = 200 + 245 + 125 = 570

Total frequency = 1000

P (families with 3, 4 or 5 people) = (570 / 1000) × 100 = 57%

Answer:

The solution is x = 6 and y =1

Explanation :

In the substitution method we solve a system of equation by substituting the value of one variable from an equation to the another equation,

Given system of equations,

x-y = 5  ⇒ y = x - 5.......(1)

2x+y = 13.......(2)

Substitute the value of y from equation (1) to equation (2),

2x+x-5=13

3x-5=13

3x=18

x = 6

Again from equation (1),

y = 6 - 5 = 1

Final answer:

To find the height of the 7th bounce of a bouncy ball, where each bounce is 64% of the height of the previous one, use the geometric sequence formula. For the first bounce's height of 5.5 feet and a common ratio of 0.64, calculate the 6th power of 0.64, then multiply by 5.5 and round to the nearest tenth.

Explanation:

The student is asking about finding the height of the seventh bounce of a bouncy ball, which follows a geometric sequence in which each term is 64% of the previous one. To find the height of the 7th bounce, we will use the formula for the nth term of a geometric sequence, which is an = a1 × r(n-1), where a1 is the first term, r is the common ratio, and n is the term number.

The first term a1 is the height of the first bounce, which is 5.5 feet, and the common ratio r is 0.64 (since 64% is 0.64 in decimal form). Using this information, the height of the 7th bounce is calculated as follows:

Calculate the 6th power of the common ratio: 0.646

Multiply this value by the height of the first bounce: 5.5 × 0.646

Round the result to the nearest tenth

Calculating the exact value and rounding to the nearest tenth gives us the height of the seventh bounce.

Step-by-step explanation:

9680 yards. Miles biked a total of 9680 yards.

The key to solve this problem is coverting the Mixed Fraction to Improper Fraction, and make the conversion from miles to yards.

Convert the Mixed Fraction 5 1/2 to an Improper Fraction:

- Multiply the whole number 5 by the denominator

5 x 2 = 10

- Add the result to the numerator

1 + 10 = 11

- Write the Improper Fraction with the same denominator of the Mixed Fraction, and the numerator with the result above

5  1/2 miles ---------->  11/2 miles

To convert miles to yard with mile = 1760 yards:

11/2 * 1760 yards = 19360 yards/2 = 9680 yards

Final answer:

Miles biked for a total of 5 1/2 miles. By converting miles to yards using the fact that there are 1,760 yards in one mile, Miles biked a total of 9,680 yards.

Explanation:

The student has asked how many yards Miles biked if he rode a total of 5 1/2 miles. To find the answer, we need to convert miles to yards. Since there are 1,760 yards in a mile, we can multiply the number of miles by this conversion factor.

First, let's represent 5 1/2 miles as an improper fraction: 5 1/2 = 11/2 miles. Next, we multiply 11/2 by 1,760:

11/2 miles
= 11/2
* 1760 yards/mile
= 11*880 yards
= 9,680 yards.

Therefore, Miles biked a total of 9,680 yards.

Answer:

180.07 rev / min

Step-by-step explanation:

Diameter (D) of each wheel =28 inches

Circumference (C) =  π x 28 = 28π inches

Conversions:

1 mile = 63,360 inches

1 hour = 60 min

Hence 15 miles / hour

= (15)(63,360) inches / hour

= (15)(63,360) / 60  inches / min

= 15,840 inches per min

Number of revolutions per min = Number of inches per min ÷ circumference in inches

=15,840 inches/min ÷ 28π inches

= 180.07 revolutions per min

To find the number of revolutions per minute a bicycle's wheels make, convert the speed from miles per hour to inches per minute, calculate the wheel's circumference, and divide the traveling speed in inches per minute by the circumference. A bicycle with 28-inch diameter wheels going 15 miles per hour makes approximately 180 revolutions per minute.

To determine how many revolutions per minute the wheels of a bicycle with a 28-inch diameter are turning when traveling at 15 miles per hour, we first need to convert the speed to inches per minute. There are 5280 feet in a mile and 12 inches in a foot, so first we calculate:

15 miles/hour * 5280 feet/mile * 12 inches/foot = 950400 inches/hour

Since there are 60 minutes in an hour, we then convert to inches per minute:

950400 inches/hour / 60 minutes/hour = 15840 inches/minute

Next, we need to find out the circumference of the bicycle wheel, as this will tell us how far the bike travels with each revolution. The formula for the circumference (C) of a circle using the diameter (d) is:

C = π * d

For a wheel with a diameter of 28 inches:

C = π * 28 inches ≈ 87.96 inches

Now, to find the number of revolutions per minute, we divide the traveling speed in inches per minute by the circumference:

15840 inches/minute / 87.96 inches/revolution ≈ 180 revolutions per minute (rounded to the nearest whole number).

Answer:

127% markup

Step-by-step explanation:

So we need to plug in 31 into each

R(31)=160(31)=4960

C(31)=71(31)-.02(31)^2=2181.78

So the selling price is 4960 for 31 stereos.

The total cost for making 31 stereos is 2181.78.

So that is a markup for sure.

So you find the difference and then divide it by the total cost.

(4960-2181.78)/2181.78=1.27 approximately

so there is 127% markup

Answer:

x=-1

Step-by-step explanation:

General equation of line is y=mx+n where m is slope. So, if we use point (-4, 8) and slope in equation we have 8= 2/3.(-4)+n

Then we have n=8+8/3, that is n=32/3

Therefore equation of our line is y=2/3.x + 32/3

For the point (x,10) in equation 10=2/3.x + 32/3

Then we have 2/3.x = - 2/3 then x= -1

Answer:

x = - 1

Step-by-step explanation:

Using the slope formula to find the slope m

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (x , 10) and (x₂, y₂ ) = (- 4, 8)

m = [tex]\frac{8-10}{-4-x}[/tex] = [tex]\frac{2}{3}[/tex], that is

[tex]\frac{-2}{-4-x}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

2(- 4 - x) = - 6 ( divide both sides by 2 )

- 4 - x = - 3 ( add 4 to both sides )

- x = 1 ( multiply both sides by - 1 )

x = - 1

(17) × (15) = 17 × 15 = 255

PLEASE DO MARK ME AS BRAINLIEST UWU

Answer:

Your answer for this question is 255.

Step-by-step explanation:

To solve this problem, we must remember how to use PEMDAS.  This tells us that we must simplify what is in parentheses first, exponents next, then multiplication and division, and finally addition and subtraction.  In this case, this means that we must first perform the operations inside of the parentheses before the multiplication of the two groups of parentheses.

If we simplify within both groups of parentheses, we get:

(2+2+3+10) * (8+9+-9+7)

= (17) * (15)

We get the above simplification by performing the addition of all of the constants in the first group of parentheses and performing the addition and subtraction in the second group (notice that the +9 and -9 cancel each other out).

Now, we must simply multiply together our final two values to obtain our final answer.

17 * 15 = 255

Therefore, your answer is 255.

Answer:

x = 30t cos 20 or  x = 28.19t.

y = 30t sin 20 - 4.9t^2 + 2 or y =  -4.9t^2 + 10.26t + 2.

Step-by-step explanation:

The horizontal component of the velocity = 30 cos 20  m/s so the distance at time t seconds = 30t cos 20.

The vertical component  is obtained from the equation of motion

s = ut - 1/2* 9.8t^2 + 2

u = 30 sin 20

Vertical component  =  30t sin 20 - 4.9t^2 + 2.

Answer:

x(t) = 30t cos 20 or we can get x = 28.19t. y = 30t sin 20 – 4.9t^2 +2 or y= -4.9t^2 + 10.26t +2

Step-by-step explanation:

The path the rock took can be represented by the following equation x(t) = v0 * cos(θ) * t y (t) = v0 * sin (θ) * t – 0.5 * g * t^2 + h. v0 is the initial velocity (30 m/s), θ is the angle of launch (20 degrees), g is the acceleration due to gravity (9.8 m/s^2) , h is the initial height (2m ) , and t is time. When we switch the values, we get x(t) = 30t cos 20 or we can get x = 28.19t. y = 30t sin 20 – 4.9t^2 +2 or y= -4.9t^2 + 10.26t +2
