An object is launched directly in the air at a speed of 72 feet per second from a platform located 12 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+72t+12, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?

Answer:

C. SSS

Step-by-step explanation:

[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]

Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.

Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.

Answer:

y [tex]\geq[/tex] 3x + 3

y < -x - 2

Step-by-step explanation:

For the first one, you can see that the slope is 3 and the y-intercept is 3, so the equation of the line would be y = 3x + 3. Then, since the shaded area is above the line it would be greater than and since the line isn't dashed it is greater than or equal to.

The completed equation is y [tex]\geq[/tex] 3x + 3

For the second one, you can see that the slope is -1 and the y intercept is -2, so the equation of the line would be y = -x - 2. Then, since the shaded area is below the line and the line is dashed, the completed equation is y < -x -2

Answer:

True

Step-by-step explanation:

The answer to this question is true.

It is worthy to note that in any two points, we have exactly one line segment that connects them together. Now the The distance that lies between both of these points is the length of this line segment which connects them. Also this distance is never negative. It is always positive.

Archimedes was the first to say that the shortest distance between two points is a straight line.

In questions given,One number is six more than a second number.

if second number is a

first number is a+6.

and,

four times the first is 10 less than 6 times the second.

So,

4×(a+6)=6a-10

we have to solve this.

[tex]\bold{4\times (a+6)=6a-10   }[/tex] 

[tex]\bold{4a+24=6a-10   }[/tex] 

[tex]\bold{6a-4a=24+10   }[/tex] 

[tex]\bold{2a=34   }[/tex] 

[tex]\bold{ a=\dfrac{34}{2}  }[/tex] 

[tex]\bold{ a=17  }[/tex] 

we,get our second number =a=17.

So,

first number =a+6=17+6=23

Step-by-step explanation: A rectangle is  a quadralaterial with 4 90 degree angles made up of two diagonals. If we draw one diagonal, it would split the rectangles into two right triangles. Since a rectangle has a right angle, we can use pythagorean theorem to solve the missing side.              

[tex]a^{2} +b^{2} =c^{2}[/tex]   where a and b are the length and widith  and c is the diagonal length. Let plug it in

[tex]30^{2} +b^{2} =50^{2}[/tex]

900+[tex]b^{2}[/tex]=2500

[tex]b^{2} =1600[/tex]

[tex]\sqrt{1600 =[/tex]40

Step-by-step explanation:

The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval: f ( x ) = x 2 , [ 2 , 3 ]

Answer:

18 jumps (if we are talking about total here)

Step-by-step explanation:

2/3 can be divided into 12/1 , and to divide you have to flip 2/3 into 3/2 and multiply the fractions. You should be left with 36/2 which simplified is 18/1, which equals 18 jumps.

Answer:

(140, 160)

Step-by-step explanation:

Let x represent model A and y represent model B.

2 lb of cast iron is needed for model A while 4 lb of cast iron is needed for model B. 920 lb of cast iron is available for production. This can be represented by the constraint:

2x + 4y ≤ 920         (1)

7 min of labor is needed for model A while 4 min of labor is needed for model B. 1620 min of labor is available for production per day. This can be represented by the constraint:

7x + 4y ≤ 1620      (2)

Also, x ≥ 0 , y ≥ 0

Plotting the constraints using geogebra app, The points that satisfy these constraints are:

(0, 230), (231.42, 0), (0,0) and (140, 160)

The profit for each model A grate is $1.50, and the profit for each model B grate is $2.40. The profit equation is:

Profit = 1.5x + 2.4y

We are to maximize profit. Hence:

At (0,0); max Profit = 1.5(0) + 2.4(0) = 0

At (0,230); max Profit = 1.5(0) + 2.4(230) = 552

At (231.42,0); max Profit = 1.5(231.42) + 2.4(0) = 347

At (140,160); max Profit = 1.5(140) + 2.4(160) = 594

The maximum profit is at (140, 160)

Answer:

The X intercepts are (-7,0) and (-3,0)

Answer:

x= -1

Step-by-step explanation:

1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.

2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.

3. That will leave you with 14x= -14.

4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.

5. That will leave you with x= -1. That is your final answer.
