Answer 1

Answer:

f(3) =-12

f(-1) =-12

Step-by-step explanation:

HELLO THERE

f(3)=-2(3)^2+8(3)

f(3)=-36+24

f(3)=-12

----------------------------

f(-1) =2(-1) ^2+8(-1)

f(-1) =-4-8

f(-1) =-12

//Both equal -12//

HAVE A GREAT DAY

Answer 2

Answer:

Step-by-step explanation:

f(x) = -2x² + 8x

f(3) = -2*(3)² +  8*3

     = - 2*9 + 24

     = - 18+ 24

f(3) = 6

f(1)= -2*(-1)² + 8*(-1)

   = -2*1  - 8

  = - 2 -8

f(1) = -10

A new car is purchased for 15700 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 10100 dollars?

Answers

Answer:

10100=15700(1-0.075)^x

10100=15700(0.925)^x

divide both sides by 15700

0.925^x=101/157

convert decimal

(37/40)^x=101/157

take the log

x= log 37/40 (101/157)

x= 5.65824

It will take almost 6 years to depreciate the value of the car to 10100 dollars.

The object below is made of solid plastic. It is a cylinder with an indentation at the top
in the shape of a cone.

What is the volume to the nearest tenth of a cubic inch, of the plastic object?​

Answers

Answer: 97.6 in3

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:

Volume of a cylinder: π (diameter /2) ^2 (height)

Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3

Volume of a cone = 1/3 π (diameter /2) ^2 (height)

V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3

Finally:

Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3

The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playing field
is 312 yards, what are its dimensions?
The width is yards

Answers

Answer:

Width of field  = 50 yards

Length of Yards =  106 yards

Step-by-step explanation:

Let the width of field be x yards

given that "The length of a new rectangular playing field is 6 yards longer than double the width"

Length of Yards= 2*width of field + 6 = 2x+6 yards

perimeter of the rectangular playing field  = 312 yards

We know that perimeter of rectangle is given by 2(length + width ).

Since field is rectangular then

2(length + width ) = 312

2(x+2x+6) = 312

=> 3x+6 = 312/2 = 156

=> 3x = 156 - 6 = 150

=> x = 150/3 = 50

Thus,

Width of field is x = 50 yards

Length of Yards=  2x+6 yards = 2*50+6  yards = 106 yards

Point D is an interior of ABC. what is m DBC can u help me pls

Answers

36.5 degrees

Step-by-step explanation:

angle abc is a straight angle ( which is 180 degrees )therefore:

angle ABD + angle DBC = angle ABC

substituting the given measurements gives us=

3x + 22 + x - 4 = 180

4x = 162

x = 40.5

the question asks us to find measure of angle DBC so we substitute x which =

measure DBC = x - 4

measure DBC = 40.5 - 4

measure DBC = 36.5 degrees

Which of the following discrete random variables could be represented by a
probability histogram whose bars are all the same height?
O A. The number of goals scored per game by a soccer team in one
season
B. The ages of students in a high school
O C. The outcomes of spinning a spinner with five equal sections
O D. The outcomes of rolling a weighted die

Answers

Answer: The outcome of spinning a spinner with five equal outcomes

Step-by-step explanation:

The discrete random variable that could be represented by a  probability histogram whose bars are all the same height is;

Option C; The outcomes of spinning a spinner with five equal sections

The probability histogram is a type of histogram whereby the height of each bar shows the true probability of each outcome of a specific number of trials.

Now, let us look at the options;

Option A; This cannot be represented by a probability histogram because it doesn't show probability.

Option B; This cannot be represented by a probability histogram because it shows just ages and doesn't show probability.

Option C; This can be be represented by a  probability histogram because it shows the probability of each outcome of spinning five equal sections.

Option D; This cannot be represented by a probability histogram because it should show the probability of each outcome and not just that of one weighted die.

What is the angle between the hands at 4:41?

Answers

Answer:127.5∘

Step-by-step explanation:

The angle measure between any two consecutive numbers on a clock is 36012=30∘.

Call the "12" point on the clock the zero-degree point.

At 4:45, the minute hand is at the "9" - that is, at the 30×9=270∘ mark. The hour hand is three-fourths of the way from the "4" to the "5; that is,

30×434=142.5∘ mark.

Therefore, the angle between the hands is

270−142.5=127.5∘, the desired measure.

D. Directrix
sig

Answers

Answer:

C

Step-by-step explanation:

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.

Focus  is the name of the point that you use to define a parabola

What is Parabola?

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped

A parabola is a symmetrical U-shaped curve that can be defined as the set of all points that are equidistant to a fixed point (called the focus) and a fixed line (called the directrix).

The vertex is the point where the parabola changes direction and is located halfway between the focus and the directrix.

The center is a term used to refer to the midpoint of the line segment connecting the two foci of an ellipse or hyperbola, and is not relevant to a parabola.

Hence,  Focus  is the name of the point that you use to define a parabola
