• Sebastian will start off by lifting 40 pounds and will increase the weight he lifts by 10 pounds each week.
Which of the following statements are true?
OOOOO
Andrew and Sebastian both increase the weight they lift each week by the same amount
Andrew's training plan can be modeled by a linear function, and Sebastian's training plan can be modeled by an exponential function.
Andrew's training plan can be modeled by an exponential function, and Sebastian's training plan can be modeled by a linear function.
Andrew increases the weight he lifts each week by equal factors, and Sebastian increases the weight he lifts each week by equal differences
Andrew increases the weight he lifts each week by equal differences, and Sebastian increases the weight he lifts each week by equal factors

Answer:

There is no graph but the graph that would have a straight line

Answer:

Whichever line is straight and does not have x repeat itself is considered linear.

Step-by-step explanation:

A linear function can be shown by using the equation y=mx+b, in which m is the slope and b is the y-intercept. A linear function must be able to follow this formula in order to be considered linear. An exponential equation, quadratic equation, or other equation will not work.

Chances are, if the line is straight and the points plotted can be connected within a straight line and not overlap, they are a linear function.

[A function being an equation in which x does not repeat itself, therefore a vertical line up and down is not considered a linear function, however, a horizontal line is.]

Answer:

answer is:

Circum: 25.13274 cm^2

Area: 50.26548 cm^2

Step-by-step explanation for the CIRCUMFERNCE ONLY:

Original equation for the circumference of a circle:

C=2(pi)r

We will use 3.14 as pi

We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.

8/2 = 4

So now we know what the radius is equal to.

4

So now just plug in your numbers to the original equation

2 X (3.14) X 4

25.13274

If we were to round up the answer would be

25.13

Answer:

y = - 3x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x + y = 3 ( subtract 3x from both sides )

y = - 3x + 3 ← in slope- intercept form

Answer:

y=-3x+3

Step-by-step explanation:

3x+y=3

y=3-3x

y=-3x+3

Answer:

-x² - 3

Step-by-step explanation:

If a function is concave down, that means the x value is negative.

Hence we know that it should be -x²

The graph is translated 3 units down

Hence:

-x² - 3

Answer:

No

Step-by-step explanation:

10 kilograms = 22 pounds

23 kilograms = ? pounds

so for this you would need to cross multiply:

(22 * 23) = 506

(10 * x ) = 10x

--> 506 = 10x

Next step is to isolate the varible (x), to do that you need to divide by 10.

x = 506/10 = 50.6

50.6lbs is more than 50lbs so no it can't get checked out

Answer:

1105.84 in³

Step-by-step explanation:

The volume of the wheel can be obtained using the formular for the volume of a cylinder :

V = πr²h ;

Height, h = 5.5 in

Radius, r = 8 in

V = π * 8² * 5.5

V = π * 64 * 5.5

V = π * 352

Volume of wheel = 1105.8406 in³

Answer:

40.5 square feet

Step-by-step explanation:

The formula for finding the area of a rhombus is (diagonal 1 x diagonal 2)/2. Since you're given the side of the rhombus, you can use the 45:45:90 degree triangle rule where the measure of the sides is 1:1:[tex]\sqrt{2}[/tex] to find the diagonals  (both equal 9 feet).

9x9/2 = 81/2 = 40.5 [tex]ft^{2}[/tex]

Answer:

The highest rate of birds is during the years 4 to 3

(remember that the lowest digit of number of negative is the highest and the highest is the lowest)

Step-by-step explanation:

Rate of Changes:

1 to 2: 5080.86 - 5238/ 2 - 1

=  -157.14/1

= (convert to decimal) -157.1

2 to 3: 4928.43 - 5080.86/ 3 - 2

= -152.43/ 1

= -152.43

3 to 4: 4780.58 - 4928.43/ 4 - 3

= -147.85/ 1

= -147.85
