Answer:

if 3 equal 8 , then 600 will be 1600.

Step-by-step explanation:

we get the points with extreme values as the 0 points of the first derivative of the function.

h'(t) = 592 - 32/7 t = 0

592 = 32/7 t

4144 = 32t

t = 129.5 seconds

so, it will reach its max. height after 129.5 seconds.

The time that the ball reaches its maximum height is 129.5 seconds.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The height above the lunar surface (in feet) after ‘t’ seconds is given by the formula;

⇒ h =592t - 16/7t²

Now,

We have to find the derivative of above formula and equate to zero for the maximum time as;

⇒ h =592t - 16/7t²

⇒ h' =592 - 16/7 × 2t = 0

⇒ 592 - 32/7 t = 0

⇒ 32/7 t = 592

⇒ 32t = 592 × 7

⇒ 32t = 4,144

⇒ t = 4,144/32

⇒ t = 129.5 seconds.

Thus, The time that the ball reaches its maximum height is 129.5 seconds.

The dimensions of the rectangular garden are 29 feet by 23 feet .

A rectangle is a quadrilateral with parallel opposite sides and equal angles. There are a lot of rectangular objects all around us. Any rectangular form's two defining characteristics are its length and width. A rectangle's longer and shorter sides are its width and length, respectively.

The area of a rectangle is given by length × width

Now the given area of the rectangle is 667 ft² .

Let the width of the rectangle is x ft. Therefore length = x + 6

Now area of the rectangle is x (x+6) = x² + 6 x

Therefore x² + 6 x = 667

or,  x² + 6 x - 667  = 0

or, (x-23)(x+29) = 0

Either x = 23 or x = -29(not possible)

Hence the width is 23 feet.

Length = 23 + 6 = 29 feet

Therefore the dimensions of the rectangle are 29 feet by 23 feet .

Answer:

Asking yourself how much you'd be willing to spend if someone else offered you a similar product.

Answer: The cost of one small box of oranges is $6, while the cost of one large box of oranges is $11.

Step-by-step explanation:

First, set x for the cost of one small box of oranges in dollars, and y for the cost of one large box of oranges in dollars.

Hence, the equations will be:

[tex]13x+5y=133[/tex]

[tex]10x+8y=148[/tex]

Then solve for the equations using the method of elimination. In order to eliminate one of the variables, you need to make the coefficients the same. So, we can multiply the first equation by 8 and the second equation by 5. That would make the equations:

[tex]104x+40y=1064[/tex]

[tex]50x+40y=740[/tex]

Then you can eliminate the y by subtracting.

[tex]54x = 324[/tex]

Then divide by 54 on both sides.

[tex]x=6[/tex]

Now that x is solved, solve for y by substituting for x.

[tex]13(6) + 5y = 133[/tex]

[tex]5y+78=133[/tex]

[tex]5y=55[/tex]

[tex]y=11[/tex]

So, x=6 and y=11.

Answer:

This is not a function

Step-by-step explanation:

Assuming that the line in question is parallel with the y axis, by using the line test we can see that the line is not a function. The line test is where you draw straight lines going vertically over the graph and if the lines touch the figure in question more than once that means it's not a function.

This can also be proved by imagining there are 2 different points on the line in question. Since the line is straight vertically that means that the points will share the same x value for different y values, which makes it not a function

Answer:

This is not a function.

Step-by-step explanation:

The questioned parallel line within the y-axis does not meet the requirements to be a function. The line test, as the other person stated, is a test where lines are drawn over the points to determine if the graph / model is, or is not a function. Doing so in this process, if the lines touch the same point more than once, that means the graph is not a function.

Step-by-step explanation:

f(x) = 2x

g(x) = -8x + 2

h(x) = x² + x + 3

= f(g(6))

= 2x

= 2.(-8x + 2)

= 2.(-8.6 + 2)

= 2.(-48 + 2)

= 2.(-46)

= -92

= g(h(-4))

= -8x + 2

= -8.(x² + x + 3) + 2

= -8.((-4)² + (-4) + 3) + 2

= -8.(16 - 1) + 2

= -8.15 + 2

= -120 + 2

= -118

= g(f(x))

= -8x + 2

= -8.(2x) + 2

= -16x + 2

The height of the tree is 21 feet if manny stands 512 feet tall, and his shadow is 414 feet long. The tree's shadow extends 17 feet in length.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

The length of Manny's shadow, which is 414 feet long, is 512 feet.

The tree's shadow extends 17 feet.

Here, we'll assume that the height is x.

According to the data given, the calculation is as follows:

414 : 512 = 17 : x

⇒ 414 / 512 = 17 / x

⇒ (414)x = (512)(17)

⇒ x = (512)(17)/(414)

⇒ x =21.02

⇒ x = 21 feet

APY for Kevin's account = 1.67%

The interest on a loan or deposit that is computed based on both the original principle and the accumulated interest from prior periods is known as compound interest (also known as compounding interest). Compared to simple interest, which is computed just on the principal amount, it will cause a sum to increase more quickly.

The frequency of compounding determines the pace at which compound interest accumulates. The compound interest increases with the number of compounding periods.

APY = [tex](1 + \frac{r}{n})^{n} - 1[/tex]  =   [tex](1 + \frac{1.667}{365})^{365} - 1[/tex]  =  1.0167 - 1 = 0.0167

Answer:

A Cartesian Plane is a plane in Geometry which is an flat surface of infinite size. It has two number lines that intersect at right angles at their zeros. One number line is horizontal, and the other number line is vertical. The point of intersection is the zero of each line. In the horizontal line, the numbers increase to the right. In the vertical line, the numbers increase up. The horizontal line is called the x axis. The vertical line is called the y axis. The center of the Cartesian Plane is the intersection of the two axes, the two number lines, and is called the origin. Points on the Cartesian Plane are described with two numbers in parentheses separated by a comma. The position of the point in the Cartesian Plane is given by the first number, called the x-coordinate, telling us the number of units to the right (positive) or left (negative) of the origin and by the second number, called the y-coordinate, telling us the number of units up (positive) or down (negative) from the origin.

Drone nerds will get 15 Mavic air 2's for $23196.192 after offering a chain discount of 6/4/3.

Chain discount is the series of discounts that are offered from the list price of an object when bought from a store.

A general example of a 10/5 chain discount denotes that there will be a series of discounts on the list price. First a discount of 10% is awarded on the list price then a further 5% on the reduced price.

The List price of the drones is $26500.

Chain discount=6/4/3

So the first discount received is 6% on the $26500.

Price after the first discount=26500- 6%of 26500

Simplifying we get

[tex]=26500-.06\times26500\\=24910[/tex]

The price after the first discount is $24910

Now we will apply the 4% discount on $24910

Price after second discount=24910-4% of 24910

$2000 was invested at 5% and $5000 was invested at 8%.

Step-by-step explanation:

Assuming the interest is simple interest.

Simple Interest Formula

I = Prt

where:

Given:

Create two equations from the given information:

[tex]\textsf{Equation 1}: \quad \sf P_1+P_2=7000[/tex]

[tex]\textsf{Equation 2}: \quad \sf P_1r_1t+P_2r_2t=I\implies 0.05P_1+0.08P_2=500[/tex]

Rewrite Equation 1 to make P₁ the subject:

[tex]\implies \sf P_1=7000-P_2[/tex]

Substitute this into Equation 2 and solve for P₂:

[tex]\implies \sf 0.05(7000-P_2)+0.08P_2=500[/tex]

[tex]\implies \sf 350-0.05P_2+0.08P_2=500[/tex]

[tex]\implies \sf 0.03P_2=150[/tex]

[tex]\implies \sf P_2=\dfrac{150}{0.03}[/tex]

[tex]\implies \sf P_2=5000[/tex]

Substitute the found value of P₂ into Equation 1 and solve for P₁:

[tex]\implies \sf P_1+5000=7000[/tex]

[tex]\implies \sf P_1=7000-5000[/tex]
