Answer:

25 - n

Step-by-step explanation:

n is a variable. It can represent any number. For example, 5 years ago, Mario would be 20 years old since 25-5 is 20.

So, if n is 8, you have to do 25 - 8 to find the answer to how old Mario was 8 years ago.

So his age n years ago, is 25 - n.

Answer:

Step-by-step explanation:

f(x) = 2x⁴ - 5x³ + 7x - 3

f(2) = 2(2^4) - 5(2^3) + 7(2) - 3

f(2) = 32 - 40 + 14 - 3

f(2) = 3

The graph below shows what happens when x = 2 and y = 2x⁴ - 5x³ + 7x - 3

Notice that the graph shows the same intersect point (2,3) as what we got when putting x = 2  into the equation.

Answer:

the answer is 12

Step-by-step explanation

Answer:

Part A

The Quadratic Function to model the total number of bricks the stack is f(x) = x²

Part B

The number of bricks we will have for 50 rows is 2500 bricks

Step-by-step explanation:

Part A

Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c

We have;

When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0

∴ c = 0

When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1

∴ a + b = 1...(1)

When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2  = 4

∴ 4·a + 2·b = 4...(2)

Multiply equation (1) by 2, and subtract it from equation (2) gives;

4·a + 2·b - 2×(a + b) = 4 - 2 × 1

2·a = 2

a = 1

From equation (1), we have;

b = 1 - a = 1 - 1 = 0

b = 0

∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²

Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²

Part B

If there are 50 rows in the stack, then we have, x = 50

Therefore;

f(50) = 50² = 2500

The number of bricks we will have for 50 rows is f(50) = 2500 bricks

y=-x+1

Step-by-step explanation:

y=-x+4

Substitute (0,1)

1=0+1

-1 is the gradient, if parallel then the gradient stays the same

Answer:

y = - x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept

y = 4 - x , that is y = - x + 4 ← in slope- intercept form

with slope m = - 1

The slope crosses the y- axis at (0, 1 ) ⇒ c = 1

y = - x + 1 ← equation of parallel line

(-46.2)÷60/7

-323.4/60

-5.39

Required value of (w²x−3)÷10⋅z when w=−6, x = 1.2, and z=−6/7 is (-4.69)

What is the value of of (w²x−3)÷10⋅z when w=−6, x = 1.2, and z=−6/7 ?

We know,

By BODMAS rule,

B - Bracket

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

We should maintain the following sequence,

Bracket - Of - Division - Multiplication - Addition - Subtraction

We are applying BODMAS rule.

Here,[tex]( {w}^{2} x - 3) \div 10 . z[/tex] and w=−6, x = 1.2, and z=−6/7

We are putting value of w,x,z in given expression and get

[tex]( {( - 6)}^{2} \times 1.2 - 3) \div 10 ( - \frac{6}{7} ) \\ = -(36 \times 1.2 - 3) \div \frac{60}{7} \\ = -(43.2 - 3) \div \frac{60}{7} \\ = -40.2 \div \frac{60}{7} \\= -40.2 \times \frac{7}{60} = -4.69[/tex]

Therefore, Required value of the given term is (-4.69)

Answer:

6 stops

Step-by-step explanation:

well if you stop every 2 1/4 miles for 13 1/2....13 1/2 divided by 2 1/4 is 6. So they'll stop 6 times.

The number of rest stops before finishing the trail is 5 rest stops.

Given,

You are hiking along a trail that is 13½ miles long.

you plan to rest every 2¼miles.

We need to find how many rest stops will you make.

We divide the given value by the total number of items we want to distribute.

Example:

In 35 minutes how many 5 minutes?

= 35/5

= 7

We have,

Trail distance = 13 1/2 miles = 27/2 miles

Distance travelled before every each = 2 1/4 miles = 9/4 miles

The number of 4/9 miles in 27/2 miles.

= 27/2 / 9/4

= 27/2 x 4/9

= 27x4 / 2 x 9

= 3 x 2

= 6 times.

This means on the 6th time you have already finished the trail so,

You have rested 5 times before finishing the trail.

Thus the number of rest stops before finishing the trail is 5 rest stops.

The point of intersection of y = 2x – 3 and y = 1 is (2,1).

Here, we have,

given that,

the equations are:

y = 2x – 3 ....1

and y = 1 .....2

now, we have to solve them.

so, putting the value of y from 2, in 1,

we get,

2x – 3 = 1

or, 2x = 4

or, x = 2

so, we have,

Answer:

w = 21 feet

Step-by-step explanation:

The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Let's say the length of a rectangle is L while the width is W.

According to the given, L = 3W - 5

The perimeter of the rectangle is given as 2( length + width)..

Perimeter = 2(L + W)

2(3W - 5 + W) = 158

4W - 5 = 79

W = 21 feet.

Hence "The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet".
