The force of gravity on the surface of jupiter is about 2.5 times as strong as that on earth. ON jupiter, the height of a ball dropped from a 100-meter tower is given by the function h(t) = -25t +100 meters at t seconds. How many seconds will it take for the ball to hit the ground?

Answers

Answer 1

Answer:

4 seconds

Step-by-step explanation:

Given

[tex]h(t) = -25t + 100[/tex]

Required

Determine what time it hits the ground

When the ball is on the ground, the height is at 0

i.e.

[tex]h(t) = 0[/tex]

Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]

[tex]0 = -25t + 100[/tex]

Collect Like Terms

[tex]25t = 100[/tex]

Solve for t

[tex]t = 100/25[/tex]

[tex]t = 4[/tex]

Hence, the ball will hit the ground in 4 seconds

Find x and y intercepts!! show work plzzz

Answers

Answer:

(-15, 0) --> x intercept

(0, 15) --> y intercept

Step-by-step explanation:

First, you need to find the equation of the line:

gradient equals 1 --> (6 - 11)/(-9 - (-4))

y = x + c

sub point (-9, 6)

6 = -9 + c

c = 6 + 9

c = 15

Equation of line: y = x + 15

x-intercept is when y = 0

0 = x + 15

x = -15 (that's the x-intercept)

(-15, 0)

y-intercept is when x = 0

y = 0 + 15

y = 15 (this is the y-intercept). The y-intercept is also the contant 'c'

(0, 15)

Step-by-step explanation:

An isosceles triangle has two sides of equal length. In this triangle, there is a little line in the middle of two out of the three sides of the triangle. This line tells us that those two sides are equal. We know that the value of these sides are 4x - 8 and 2x + 12. So, to find the value of x, we can set the equations equal to each other and solve for x:

4x - 8 = 2x + 12

Subtract 2x from both sides to isolate x:

2x - 8 = 12

Add 8 to both sides:

2x = 20

Divide both sides of the equation by 2 to find the value of x:

x = 10

The answer is the second one x=-1/2

solve for x:
-6 + 4x = 13

Answers

Answer:

x = 19/4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-6 + 4x = 13

Step 2: Solve for x

Add 6 to both sides:                    4x = 19Divide both sides by 4:                x = 19/4

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    -6 + 4(19/4) = 13Multiply:                        -6 + 19 = 13Add:                               13 = 13

Here, we see that 13 does indeed equal 13.

∴ x = 19/4 is a solution of the equation.

x=4.75

explanation: you would subtract -6 since there is an invisible adding sign and then you would subtract -6 from both sides so you would do 13- -6 and that would give you 19. so then it would be 4x=19 and you would divide by 4 since you are doing inverse operation so 19 divided by 4 is 4.75

A rectangle has a perimeter of 42 m and a length of 15 m. What is
the width of this rectangle in metres? (Perimeter = 2(length + width))

Answers

Answer:

6 meters

Step-by-step explanation:

the perimeter is all of the sides added up so to find the added width you subtract the added length which is 30 so 42-30 is 12 so the added width is 12. To find one width you divide 12 by 2 so one width of the rectangle would be 6 meters

Answer:

Step-by-step explanation:

The correct option is (B).

What is an Inequality?

In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa. If the relationship between two algebraic expressions is defined using the inequality symbols, then it is called literal inequalities.

Given,

Number of windows Jason can install in 1 hour = 6 ≤ x ≥ 8

Time taken in installing 1 window = 1/6 ≤ 1/x ≥ 1/8

Time taken in installing 100 windows = 1/6 × 100 ≤ 1/x × 100 ≥ 1/8 × 100

Time taken in installing 100 windows = 12.5 ≤ t ≥ 16.67

Then the possible amount of time taken will be in range of 12.5 to 16.67 hrs.  

Hence, Jason will take around 16 hrs. to install 100 windows.
