a diver dives from a 10m springboard. the equation f(t)=-4.9t^(2)+4t+10 models her height above the pool in seconds. what is her height at 1.5 second after diving off the springboard

Answers

Answer 1

Answer:

4.975 meters

Step-by-step explanation:

[tex]f(1.5)= -4.9(1.5)^2+4(1.5) + 10\\\\f(1.5) = -4.9(2.25) + 6 + 10\\\\f(1.5) = -11.025 + 6 + 10\\\\f(1.5) = -11.025 + 16 \\\\f(1.5) = 4.975[/tex]

4.975 meters

Charlie is making chocolate cake for his birthday party. He found a recipe that needs 2 cups of cocoa powder for every 3 cups of sugu. Al of his friends

are coming, so he uses 6 cups of cocoa powder in his cake,

How many cups of sugar should Charlie uso?

Answers

Step-by-step explanation:

the mix follows the ratio 2/3 (cups of cocoa to sugar).

2 × x = 6 cups

x = 6/2 = 3

so, the cocoa cups number is multiplied by the factor 3, and we need to multiply also the sugar cup number with the same factor to keep the ratio value unchanged :

so, we need 3×3 = 9 cups of sugar.

What is the area of this figure?

Answers

Given :-

A figure is given to us .

To Find :-

The area of the figure .

Solution :-

As we can see that the given figure is made up of a parallelogram and a ∆ . As we know that the opposite sides of a parallelogram are equal . So that the base of the ∆ would be 9cm . Now ,

[tex]\longrightarrow[/tex] Area = ar(||gm ) + ar(∆)

[tex]\longrightarrow[/tex] Area = (9*5 + 1/2*8*9)cm²

[tex]\longrightarrow[/tex] Area =( 45 + 45 ) cm²

[tex]\longrightarrow[/tex] Area = 90cm²

Hence the area of the given figure is 90cm² .

Find the inverse (pre-calc)

Answers

Answer:

f^(-1)(x) = e^(x/3)

Step-by-step explanation:

1.  Replace 'f(x)' by 'y:'  y = 3ln x

2. Interchange x and y:  x = 3ln y => x/3 = ln y

3. Solve for y:  

   e^(x/3) = y

4.  Replace this 'y' with 'f^(-1)(x)'

    Then f^(-1)(x) = e^(x/3)

b. 20/100 = 1/5

c. 25/100 = 1/4

Answer:

Step-by-step explanation:

You are working with 1 large square made up of 100 little squares. The little squares make up 10 columns of 10 little squares each.

A

Shaded part = 30 squares.

Entire large square = 100 small squares

% = 30 / 100 * 100 = 30%

B

Shaded part = 20 horizontal squares.

Entire large square = 100 small squares

% = 20 / 100 * 100 = 20%

C

Shaded part = 5 by 5 little squares = 25 little squares

Entire large square = 100 small squares

% = 25 / 100 * 100 = 25%

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

18 ounces. of iced tea costs 2.99. Then the ratio of cost to weight is calculated as,

⇒ $2.99 / 18

⇒ $0.166 per ounce

Then the cost of 30 will be calculated as,

⇒ $0.166 x 30

⇒ $4.98

The cost of 30 ounces of iced tea will be $4.98.
