If a rock is thrown upward on the planet Mars with a velocity of 17 m/s, its height (in meters) after t seconds is given by H = 17t - 1.86t2.

Step-by-step explanation:

In order to make a profit R > C

So let's make those equal first

R = C

[tex]6.56x = 10.063 + 1.09x[/tex]

Let's get X alone by subtracting 1.09x from both sides.

[tex]5.47x = 10.063[/tex]

Next we divide by 5.47

Answer:

  D. y = x² +7x +10

Step-by-step explanation:

You want the function that describes a graph showing a quadratic with roots of -5 and -2.

The factored form of the equation can be written from the x-intercepts (roots) by considering that a root of p means (x -p) is a factor. The factored equation is ...

  y = (x -(-5))(x -(-2)) = (x +5)(x +2) . . . . . doesn't match A or B

When this is multiplied out, it becomes ...

  y = x² +5x +2x +10 = x² +7x +10 . . . . . . matches choice D

The equation is y = x² +7x +10.

Answer:

Step-by-step explanation:

6 - 3/4x + 1/3 = 1/2x + 5

6 - 9/12x + 4/12 = 6/12x + 5  If I multiply all the way through by 12 I will eliminate the fraction

Answer:

k = 176

Step-by-step explanation:

16 = k/11

16 * 11 = k/11 * 11

176 = k

Because k is being divided by 11 on the right-hand side of the equation, we would need to multiply both sides by 11 to undo the division operation done to k so we can isolate it.

The height of the right cylinder is 0.011 inches approximately.

Volume Definition:

Every three-dimensional object occupies some space. It is being determined how big this area is. Volume is the term used to describe the area contained within an object's three-dimensional boundaries. It is referred to as the object's capability on sometimes.

‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Now in the given question,

Circumference,

[tex]2\pi r[/tex] = [tex]\frac{41}{4}[/tex]

[tex]r=\frac{41}{8\pi }[/tex]

V = 9 cubic inches

volume of cylinder = πr²h = 3.14×[tex]\frac{41}{8\pi }^2[/tex]×h

h = (9)÷(3.14×[tex]\frac{41}{8\pi }^2[/tex]) = 0.011 inches

Answer:

They would need 35 cups of rice.

Step-by-step explanation:

4 x 5 = 20

7 x 5 = 35

The coordinates can be determined by using mid point formula. Here the coordinates vertex C is (2,8), vertex A is (0,2) and vertex T is (6,4)

Here the midpoints are (1,5) , (4,6), (3,3).

By using mid point equation, x₁+x₂/2 = 1

So x₁+x₂ = 2  --------------------> eq 1

x₂+x₃/2 = 3

x₂+x₃ = 6   -----------------------> eq 2

x₁+x₃/2 = 4

x₁+x₃ = 8 -----------------------> eq 3

Adding equations 1,2,3

2( x₁+x₂+x₃) = 16

 x₁+x₂+x₃ = 8 ---------------> 4

Determining x-coordinates

Subtracting equation 1 from 4

x₁+x₂+x₃ -(x₁+x₂) = 8-2

 x₃ = 6

Similarly subtracting equation 2 from 4

x₁+x₂+x₃ -(x₂-x₃) = 8-6

x₁ = 2

Subtracting 3 from 4

x₁+x₂+x₃ -(x₁+x₃) = 8-8

x₂ = 0

Determining y coordinates

y₁+y₂/2 = 5

y₁+y₂ = 10 ----------------> 5

y₁+y₃/2 = 6

y₁+y₃ = 12 ----------------> 6

y₂+y₃/2 = 3

y₂+y₃ =6   -------------->  7

Adding equations 5,6 and 7

2(y₁+y₂+y₃) = 28

y₁+y₂+y₃ = 14 -----------------> 8

Subtracting equations 5,6 and 7 from 8

y₁+y₂+y₃ -(y₁+y₂) =14 - 10

y₃ = 4

y₁+y₂+y₃ -( y₂+y₃) = 14- 6

y₁ = 8

y₁+y₂+y₃-(y₁+y₃) = 14- 12 = 2

So the coordinates are (x₁ , y₁) =(2,8)

                                       (x₂, y₂) = (0, 2)

                                       (x₃, y₃) = (6,4)

So the coordinates of C,A and T are (2,8) , (0,2) and (6,4) respectively.

The cost of one candy bar is $2.35.

The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service.

Given that, there are 30 king-sized candy bars in a box and the box sells for $70.50, we need to find that how much does each candy bar in the box cost,

Since, the cost of all 30 candies is given collectively, i.e. $70.50,

We will divide the cost of the whole box by the number of candies to find the unit price of the candies,

Unit price = $70.50 / 30

Answer:

y = -140x + 1400

Step-by-step explanation:

First, we'll find the slope, m, using the formula:

m = (160 - 780) / (8 - 4) = -620 / 4 = -155

Next, we'll use one of the points and the slope to find the y-intercept, b:

b = y - mx

We'll use the point (4, 780) to find b:

b = 780 - (4 * -155) = 1400

So the equation that models the balance, y, after x months is:

y = -155x + 1400

And since -155 can be simplified to -140, the equation becomes:

y = -140x + 1400

Answer:

21°

Step-by-step explanation:

For this right-angled triangle:

∠M = angle in question

Side LM = Hypotenuse

With respect to ∠M:

Side LN = Opposite side

Side MN = Adjacent side

Trigonometric function applied:

sin∠M = [tex]\frac{opposite}{hypotenuse}[/tex]

           = [tex]\frac{8}{22}[/tex]

 ∠M = [tex]sin^{-1} (\frac{8}{22})[/tex]

          = 21.32°

  ∠M  = 21° (Rounded to the nearest degree)

Answer:

∠M = 21°

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the given right triangle:

Therefore, substitute the given values into the sine ratio and solve for ∠M:

[tex]\implies \sin(M)=\dfrac{8}{22}[/tex]

[tex]\implies M=\arcsin \left(\dfrac{8}{22}\right)[/tex]

[tex]\implies M=21.323686...^{\circ}[/tex]

[tex]\implies M=21^{\circ}\sf\;(nearest\;degree)[/tex]

Answer: x = -3/2 , x = -1 1/2 , x = -1.5

Step-by-step explanation:

6/-4.5 = 8/4x

first determine the defined range --> x ≠ 0

cancel out the common factor 4 --> 6/-4.5 = 2/x

the convert the decimal into a fraction --> 6/-9/2 = 2/x

now use -a/b = a/-b = -a/b to rewrite the fraction --> 6/-9/2 = 2/x

then simplify the complex fraction --> -4/3 = 2/x

simplify the equation using cross-multiplication --> -4x=6

divide both side of the equation by -4 --> x = -3/2 , x ≠ 0

lastly, check if the solution is in the defined range --> x = -3/2

solution : x = -3/2

Alternative form: x = -1 1/2 , x = -1.5 (simplified)

Answer:

give me more instructions so i can actually help

Step-by-step explanation:

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

If the ratio is 5: 3, (girls: boys) we can use this equation to figure out how many boys there are if there are 35 girls:

We can see that in the ratio 5: 3, 5 is being multiplied by 0.6 to get three. If the relationship between the numbers 5 and 35 stays proportional, we multiply 35 by 0.6.

Therefore, the ratio of girls to boys is 35: 21, meaning there are 21 boys.

Answer: Let x be the number of servings of Designer Whey and y be the number of servings of Muscle Milk.

We know that:

x + y = 7 (because you want 7 days of supply)

And the protein content per serving of Designer Whey is 18g and the protein content per serving of Muscle Milk is 20g. So:

18x + 20y = 412 (because you want 412g of protein)

And the carbohydrate content per serving of Designer Whey is 4g and the carbohydrate content per serving of Muscle Milk is 8g. So:

4x + 8y = 108 (because you want 108g of carbohydrates)

We can now use the above two equations to solve for x and y. We'll start by solving for x in terms of y:

18x + 20y = 412

18x = 412 - 20y

x = (412 - 20y)/18

Now we can substitute this expression for x into the equation for the carbohydrates:

4x + 8y = 108

4((412 - 20y)/18) + 8y = 108

1664 - 80y + 8y = 1080

1664 = 1080 + 80y

584 = 80y

y = 7.3

Since y must be an integer, we'll round it down to 7. So y = 7. We can now use either equation to find x:

18x + 20y = 412

18x + 20 * 7 = 412

18x = 412 - 140

18x = 272

x = 15.1

Since x must be an integer, we'll round it up to 15. So x = 15.

Therefore, you should combine 15 servings of Designer Whey and 7 servings of Muscle Milk in order to meet your requirements.
