Answer:

Step-by-step explanation:

Height:  h(t)= -0.2t^2+2t  =  2t(-0.1t + 1)

-0.2t^2+2t  is  a quadratic expression with a = -0.2 and b = 2.

The ball reaches its max height at t = -b/(2a).

Here, t = -2 / (2·[-0.2] ), or  t = 2/0.4 = 5 (sec)

The ball reaches its max height at at 5 sec.

The max ht. of the ball is h(5) = -0.2(5 sec)^2 + 2(5 sec) = (-5 + 10) sec, or 5 ft.

To determine after how many sec the ball reaches the ground, we set h(t) = 0 and solve for t:  

h(t)= -0.2t^2+2t = 0 = 2t(-0.1t + 1).  Thus, t = 0 sec or t = 10 sec

The ball reaches the ground again after 10 sec.

Answer:

5 : 3

Step-by-step explanation:

Given in the question that,

total number of animal feet = 26

number of pig's feet = 20

number of chicken's feet = 6

As we know that pig have four legs and chicken have 2 legs so,

number of pigs in the farm = 20/4 = 5

number of chickens in the farm = 6/2 = 3

Questions says that there are 8 heads so we can confirm our calculations as

The ratio of the number of pigs to the number of chickens is

376900x.2= 75380.......

To find 20 percent of 376,900, multiply it by 0.2, which equals 75,380.

To find 20 percent of 376,900, you can multiply 376,900 by 0.2.

20 percent, written as a decimal, is 0.2.

Multiplying 376,900 by 0.2 gives you 75,380.

Answer:

what are on the tabs

Step-by-step explanation:

The ordered pair given in the first row of the table can be written using Function notation as (x, f(x)), which is (3, -2).

f(3) is -2.

f(x) = -5 when x is 4.

Now, let's complete the statements:

f(3) is -2.

This statement tells us that when the input value (x) is 3, the function f(x) evaluates to -2. In the table, you can see that when x = 3, f(x) is indeed -2.

f(x) = -5 when x is 4.

This statement indicates that when the input value (x) is 4, the function f(x) takes on the value of -5. In the table, you can see that when x = 4, f(x) is -5.

In summary, these statements highlight specific values of the function f(x) for particular input values (x) based on the table of values provided. The function notation f(3) = -2 indicates that when x = 3, the function returns -2, and the statement f(x) = -5 when x is 4 tells us that when x = 4, the function evaluates to -5, as observed in the table.

Answer:

Graph A.

Step-by-step explanation:

We will try to understand the graph plotted for the change in temperature for whole day.

In the morning, temperature starts out around 50°F. As the day goes on, the temperature rises first slowly- Slope of the first line will be less.

Then temperature rises more quickly - Slope of the second line will be more than first line.

It stays constant for an hour- third line will be parallel to the x-axis for one hour gap.

Then the temperature dropped down slowly - Last line of the graph will go down.

By the understanding we made for the graph we find graph A is the answer.

Answer:

yes B is the correct answer, the perimeter would be 16

Answer:

B and 16

Step-by-step explanation:

It's B because all the other answers would make a rectangular shape. You can find the plots on the lie by figuring out what coordinate each number is. For example, (3,1) the 3 is the x coordinate and 1 is the y coordinate. To find the perimeter you count the the boxes between the dots. 1 side is 4 and since it's the other sides are 4 you add it up to get 16 units squared.

To solve any questions relating to ages, I find it easier to make a table, like in the picture below.

See picture for answer and clear diagram.

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

Notes/Explanations + answer in written form

Let's say that Halley's age now is:              x

That means that her age in 18 years is:      x + 18

It also means that her age 2 years ago is:   x - 2

In the question, we are told that when Halley is 18 years older that her current age, she will be 5 times the age she was when she was 2 years younger than her current age

That means:

Halley's current age + 18 years = 5 times (Halley's current age - 2 years)

So we get this equation (which we solve to get the answer) :

x + 18 = 5 * (x -2)                       ( expand the brackets)

x + 18 = 5x - 10                           (subtract x from both sides)

18 = 4x - 10                                 (add 10 to both sides)

28 = 4x                                       (now divide both sides by 4)

7 = x

Therefore, Halley's current age is 7 years

Solution:

Given Expression is 1/40* x = 1/8

Step : Define x in the Equation:

Step : Divide the Equation by 8

Step : Do cross multiplication

Step : Arrange it in particular form

____________________________

☞ 1/40x = 1/8

☞ x/40 = 1/8

☞ x = ⅛ × 40

☞ x = 5

.

Therefore, Answer is 5.

x = 5

1/40 of x is the same x divided by 40, so let’s put that into the equation to get x/40 = 1/8.

Now, multiply both sides of the equation by 40 to cancel out the division by 40.

x = 1/8 * 40

x = 40/8

Now, just simplify.

x = 5

y=-2x+3 in slope-intercept form

3 is the y-intercept and -2 is the slope

Answer:

2x - y + 3 = 0

Step-by-step explanation:

The formula used to find the equation is:

[tex]y-y_1= \frac{(y_2-y_1)}{(x_2-x_1)} (x-x_1)[/tex]

Here, (x₁, y₁) = (0, 3)

and (x₂, y₂) = (1, 1)

Putting all values in above formula,

[tex]y-3= \frac{(1-3}{(1-0)} (x-0)[/tex]

⇒  [tex]y - 3 =\frac{-2}{1}x[/tex]

⇒ y - 3 = 2x

⇒ 2x - y + 3 = 0

which is the requires equation.

The volume of a cube is V = s³, where s represents the length of one edge.

Here, V = s³ = 1953.125 cm³, and we need to solve for s.  Do this by taking the cube root of both sides:

s = ∛( 1953.125 cm³ ) = 12.5 cm

Answer:

The answer is B.

Step-by-step explanation:

the angle is not even 90 degrees so anything bigger is an automatic no and it's pretty obvious that the answer is not 0. Lol

The approximate measure of an angle can be estimated using nearby or known angles as reference points or by using a protractor.

The approximate measure of an angle can be determined using various methods, including estimation or using a protractor. If you are estimating the measure of an angle, you can use nearby angles or known angles as reference points. For example, if you have a right angle measuring 90 degrees, and the given angle appears to be slightly less than a right angle, you can estimate it to be around 85-88 degrees.

Alternatively, you can use a protractor which is a tool specifically designed to measure angles. Place the center of the protractor on the vertex of the angle and line up one of the lines on the protractor with one of the sides of the angle. Read the measurement indicated on the protractor scale to determine the approximate measure of the angle.

Answer:

15 degrees

Step-by-step explanation:

3.5 times 10 = 35

50-35=15

Answer:

29 Degrees Fahrenheit

Step-by-step explanation:

So at 4,000 ft. high, it's 50 Degrees Fahrenheit, that means we don't need the first 4,000 because 50 is our starting point. 10,000 - 4,000 = 6,000.

Every 1,000 ft. is down another 3.5 Degrees Fahrenheit, and so first we divide 6,000 by 1,000 to have 6.

Then we multiply 3.5 with 6 to get 21 Degrees Fahrenheit.

50 - 21 = 29 Degrees Fahrenheit.

The approximate surface area of a cylinder with a height of 12 meters and a base radius of 2 meters is 175.84 square meters, using 3.14 for pi.

The question asks for the approximate surface area of a cylinder with specific dimensions, using 3.14 for π. The surface area of a cylinder can be calculated through the formula for surface area which includes the areas of the two bases and the side surface. The area of one base is πr², which is the area of a circle. For our cylinder, with a base radius (r) of 2 meters, the area of one base is 3.14 × (2 m)² = 12.56 m². Since the cylinder has two bases, you double this area. The side surface is a rectangle when rolled out, and its area is the perimeter of the base circle (circumference) times the height (h) of the cylinder. The circumference (C) of the base is 2πr, so for our cylinder C = 2 × 3.14 × 2 m = 12.56 m. The side surface area is therefore C × h = 12.56 m × 12 m = 150.72 m². Add the areas of the two bases and the side surface to find the total surface area: 2 × base area + side surface area = 2 × 12.56 m² + 150.72 m² = 175.84 m².
