Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3

Answer: 128.5 gallons

Step-by-step explanation:

V= πr²h

V=π15²42

V= 29688.05058in³ ÷ 231 ≈ 128.5 gallons

The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

The margin of error (E) for a confidence interval is described as:

E = z × (σ / √n)

where:

E is the desired margin of error

z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)

σ is the population standard deviation

n is the sample size

In this case, the margin of error is no more than ±1 inch, so E = 1 inch.

Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.

For a 99% confidence level, the z-score is approximately 2.576.

Plugging in the known values into the margin of error formula,

1 = 2.576 × (2.4 / √n)

To solve for n, rearrange the formula as follows:

√n = (2.576 × 2.4) / 1

√n = 6.1824

n = (6.1824)²

n ≈ 38.16

Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

Step-by-step explanation:

√224.71=14.99

r= 14.99

d= 29.98

round up to 30

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Answer:

23

Solving steps

We know x= -10-15y, so we can subtract it to the equation above

x = -10-15y

2x+5y=35

2(-10-15y) + 5y = 35

(Refer to the 1st image to solve for y)

Y = -11/5

We now know y= -11/5, so we can subtract it to the equation for x.

Y = -11/5

x = -10-15y

x = -10-15(-11/5)

(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)

x = 33 - 10

x = 23

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

[tex]\overline{GE}[/tex] ≈ [tex]\overline{FG}[/tex]

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.
