Answer 2

Answer:

Answer is B, V = π(7)² · 20

Step-by-step explanation:

the formula for a cylinder is V = πr²h

So, from here you just plug in numbers.

but for "r" you need to take 14 and divide it by 2 since it is in the form of a diameter which is different to a radius or "r".

14/2 = 7

Now, you can plug in numbers,

V = π(7)² · 20

please help with math problem !! (explanation needed) -3 + (8 – 2x)4 = 29

Answers

Answer:

x = -4

Step-by-step explanation:

To solve this type of question, put the term with the exponent on one side and the numerical term on the other side

∵ -3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29

→ Add 3 to both sides

∵ -3 + 3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29 + 3

∴ [tex](8-2x)^{\frac{5}{4}}[/tex] = 32

→ Remember is [tex]x^{\frac{m}{n}}[/tex] = a, then x = [tex]a^{\frac{n}{m}}[/tex], that means to move the exponent

   from one side to the other side reciprocal it

∴ 8 - 2x = [tex](32)^{\frac{4}{5}}[/tex]

→ Use your calculator to find the value of  [tex](32)^{\frac{4}{5}}[/tex]

∵  [tex](32)^{\frac{4}{5}}[/tex] = 16

∴ 8 - 2x = 16

→ Subtract 8 from both sides

∴ 8 - 8 - 2x = 16 - 8

∴ -2x = 8

→ Divide both sides by -2

x = -4

To check the solution substitute x by -4 in the left side and find its answer if it equals the right side, then the solution is right

∵ Left side ⇒ -3 + (8 - 2 × -4)[tex]^{\frac{5}{4}}[/tex] = -3 + (8 + 8)[tex]^{\frac{5}{4}}[/tex] =-3 + (16)[tex]^{\frac{5}{4}}[/tex]  = -3 + 32 = 29

∵ Right side = 29

∴ The solution is right

WHICH GRAPH SHOWS A FUNCTION AND ITS INVERSE.

brainliest plz hurry timed test!!

Answers

I believe the answer is D. i am not quite sure if it is absolutely correct but the lines on the graph are inverses from each other as well as a function so I am guessing that one.

A slope is also known as the gradient of a line. The correct option is B.

What is Slope?

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

Since for the two functions to be inverse of each other, the line of equations must bisect each other at 90° so that the product of the slope of the two equations is equal to -1.

For the second graph, the slope of the blue line is,

m₁ = (-1-0)/(0-4) = 0.25

The slope of the green line is,

m₂ = (-4-0)/[0-(-1)] = -4

Now, the product of the slope can be written as,

0.25×-4 = -1

Since the product is -1, the function is inverse of each other.

Hence, the correct option is B.

7. The bottom of a river makes a V-shape that can be modeled with the absolute value function,

d(h) = 1/6 |h – 300| - 50 where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbor master and you want to place buoys where the river bottom is 20 feet below the surface. If one buoy is to be placed 120 feet away from the left shore, how far should the second buoy be placed form the left shore?

(Note: A buoy is an anchored float serving as navigation mark, to show reefs or other hazards to guide ships.)

Answers

Answer:

If one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

Step-by-step explanation:

Given that:

The absolute value function:

[tex]d(h) = \dfrac{1}{6}|h - 300| - 50[/tex]

To calculate the position of the buoy where the river bottom is 20 feet below the surface, we equate the absolute value function to the negative value of 20 feet and then solve it for h.

d(h) = -20

[tex]d(h) = \dfrac{1}{6}|h - 300| - 50 = -20[/tex]

Let us add the sum of 50 on both sides, then:

[tex]= \dfrac{1}{6}|h - 300| - 50+50 = -20+50[/tex]

[tex]= \dfrac{1}{6}|h - 300| = 30[/tex]

By multiplying 6 on both sides, we have:

|h - 300| = 30 (6)

|h - 300| = 180

We can attempt the above expression by rewriting it as two equations:

h - 300 = 180   or     h  - 300  = - 180

Let us add 300 to both sides from the two expressions above:

h - 300 + 300 = 180 + 300     or   h - 300 + 300   = -180  + 300

h = 480     or  h = 120

Thus, if one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

[tex]\mathbf{d(h) = \frac 16|h - 300| - 50}[/tex] is an illustration of an absolute function.

The buoy should be placed at 480 feet from the left shore

The function is given as:

[tex]\mathbf{d(h) = \frac 16|h - 300| - 50}[/tex]

To place a buoy at 20 feet below, means d(h) = -20

So, we have:

[tex]\mathbf{-20 = \frac 16|h - 300| - 50}[/tex]

Add 50 to both sides

[tex]\mathbf{30 = \frac 16|h - 300|}[/tex]

Multiply both sides by 6

[tex]\mathbf{180 = |h - 300|}[/tex]

Remove absolute bracket

[tex]\mathbf{h - 300 = -180}\ or\ \mathbf{h - 300 = 180}[/tex]

Make h the subject

[tex]\mathbf{h = 300-180}\ or\ \mathbf{h = 300+180}[/tex]

[tex]\mathbf{h = 120}\ or\ \mathbf{h = 480}[/tex]

This means that, the buoy should be placed at 480 feet from the left shore

Answers

Answer:

x = 7 ± [tex]\sqrt{15}[/tex]

Step-by-step explanation:

Given

4(x - 7)² - 48 = 12 ( add 48 to both sides )

4(x - 7)² = 60 ( divide both sides by 4 )

(x - 7)² = 15 ( take the square root of both sides )

x - 7 = ± [tex]\sqrt{15}[/tex] ( add 7 to both sides )

Which equation represents a line that passes through the point (6,-3) and is parallel to the graph y=3x+1

Answers

Answer:

y = 3x + 6

Step-by-step explanation:

To make the equation we'll use the form y = mx + b, where m is the slope and b is the y-intercept. When a line is parallel to another, both lines have the same slope, so the slope of the equation will be 3. Now that we know the slope, we can input the point (6, -3) into the equation to solve for the y-intercept:

y = mx + b

y = 3x + b

-3 = 3(-3) + b

-3 = -9 + b

Add 9 to both sides to isolate the b:

-3 + 9 = -9 + 9 + b

6 = b

The y-intercept is 6. Let's put that into our equation:

y = 3x + 6

Now we have our answer :)

F a seed is planted, it has a 75% chance of growing into a healthy plant. If 9 seeds are planted, what is the probability that exactly 2 don't grow?

Answers

Answer:

0.3

Step-by-step explanation:

Given that:

Probability of growing into a healthy plant = probability of success (p) = 75% = 0.75

Number of seeds planted(n) = 9

Probability that exactly 2 don't grow is equivalent to having 7 that grows (9 - 2) = 7 = r

Using binomial distribution formula :

nCr * p^r * (1 - p)^(n-r)

9C7 * 0.75^7 * (1 - 0.75)^(9 - 7)

9C7 * 0.75^7 * 0.25^2

36 * 0.13348 * 0.0625

= 0.3003387

= 0.3

Hence, probability that exactly 2 don't grow is 0.3

Brad buys two packages of mushrooms. He paid $11.25 for 2/3 lb of Cremini mushrooms and $7.99 for 1/2 lb of Chanterelle mushrooms. Which mushroom cost less per pound?

Cremini mushrooms cost less by $0.10
Chanterelle mushrooms cost less by $0.10
Chanterelle mushrooms cost less by $0.90
Cremini mushrooms cost less by $0.90

Answers

Answer:

C. (Chanterelle mushrooms cost less by $0.90)

Step-by-step explanation:

Divide 11.25 by 2/3, for the total amount of pound for the Cremini.

Do the same thing for Chanterelle, but the numbers given for it.

We than find out that Cremini=16.87, and Chanterelle=15.98

Now that we know Cremini is more that Chanterelle, we need to find the difference, by subtracting The bigger number by the smaller number.

Our answer is 0.89, but we will round it to 0.90.

Now we know that the Cremini costs more by $0.90, and the Chanterelle costs less by $0.90

Answer:

Step-by-step explanation:

Cost of 1 lb of Cremini mushrooms= 11.25×3/2=33.75/2=16.875 $≈$16.88

Cost of 1 lb of Chanterelle mushrooms=7.99×2/1=$15.98

Chanterelle mushrooms cost 16.88-15.98=$0.90 less

The formula for the volume V of a cylinder is V=pier2h, where r is the radius of the base and h is the height of the cylinder. Solve the formula for h.

Answers

Answer:

h = V / πr²

Step-by-step explanation:

V = πr²h

Where,

V = volume of a cylinder

π = π

r = radius of the cylinder

h = height of the cylinder

V = πr²h

Solve for h

V = π × r² × h

Divide both sides by π × r²

h = V / π × r²

h = V / πr²

Height of the cylinder = volume of the cylinder / pie × r²
