Let ST = length of tunnel

SR = 1414 m

RT = 2236 m

Set up:

ST^2 + SR^2 = RT^2

ST^2 + (1414)^2 = (2236)

Solve for RT to find your answer.

The function (f º g)(x) is 4x⁶ + 1. Option A

A function can be defined as a law, rule or expression that shows the relationship between two variables in an equation.

These variables are called;

From the information given, we have the function;

To determine the composite function, we have to substitute the value of g(x) as x in the function f(x), we have;

(f º g)(x) = (2x³ + 1)²

expand the bracket

(f º g)(x) = 4x⁶ + 1

Hence, the function is (f º g)(x) = 4x⁶ + 1

Answer:

2.07

Step-by-step explanation:

I DID IT ON A CALCULATOR

The area of a 2D form is the amount of space within its perimeter. The area that is needed to be mowed by Brian is 2.07 acres.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.

The total area that is needed to mow is 7.84 acres. Given that Brian mows 1.291 acres on Monday, 0.85 acres on Tuesday, and 3.63 acres on Thursday. Therefore, the area already mowed by Brian can be written as,

[tex]\rm \text{The area already mowed by Brian} = 1.291 + 0.85 + 3.63= 5.771\ acres[/tex]

The area that is left to mow = Total area - Area already mowed by Brian

                                              = 7.84 - 5.771

                                              = 2.069 acres ≈ 2.07 acres

Hence, the area that is needed to be mowed by Brian is 2.07 acres.

Answer:

132, (D)

Step-by-step explanation:

area = base * height

= (5 + 6) * 12 = 11 * 12 = 132

Answer:

The answer is D, 132 cm^2! Brainleist pls!

Answer:

B = 12.8 cm (to 1.d.p)

D = 24.1 cm (to 1.d.p)

Step-by-step explanation:

Using Pythagoras Theorem:

B: 4^2 + 3.5^2 = 28.25

square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle B = 12.8 cm (to 1 decimal place)

D: 10^2 - 6.5^2 = 57.75

square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle D = 24.1 cm (to 1 decimal place)

Answer:

(7,2)

Step-by-step explanation:

Multiply the first equation by -3

(x-3y=1)  = -3x+9y=-3

Combine like terms with the new equation and the second equation

(-3x+9y=-3) + (3x-5y=11)   = 4y=8

Divide each side by 4

4y/4=8/4

y=2

Plug in 2 for y in any equation. It doesn’t matter which one

x-3(2)=1

Distribute

x-6=1

Add 6 to both sides

x-6=1

+6  +6

x=7

Answer: x = 7 y = 2

(7, 2)

Step-by-step explanation:

Multiply the first equation by -3 and the second by 1:

-3(x - 3y = 1)

1(3x - 5y = 11)

Becomes:

-3x + 9y = -3

3x - 5y = 11

Add the equations to eliminate x:

-3x + 9y = -3

3x - 5y = 11

4y = 8

Solve for y by dividing by 4:

4y/4 = 8/4

y = 2

Now we plug in y to the first equation:

x - 3 ( 2 ) = 1

x - 6 = 1

Add 6 to both sides:

x - 6 + 6 = 1 + 6

x = 7

Answer:

25 ft 3 in

Step-by-step explanation:

Mr foote deck is 12 ft 6 in wide

It's length is twice its width with additional 3 inches

Therefore the length can be calculated as follows

12 ft 6 in + 12ft 6 in + 3 in

= (12+12)ft (6+6)in + 3 in

= 24+1 3in

= 25 ft 3 in

Hence the length of the deck is 25 ft 3 in

Answer:

its an acute angle

Step-by-step explanation:

its an acute angle be cause its small than a right angle

Answer:

angle AED =  70 degrees

angle x = 10 degrees

Step-by-step explanation:

since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees

since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees

minor arc BD = 360 - 220 - 80 = 60 degrees

arc AB + arc BD = arc ABD

arc ABD = 80 + 60 = 140 degrees

angle AED = 1/2 (140) = 70 degrees

angle EAD = angle AED because isosceles

arc ED = 2(70) = 140 degrees

arc AE = arc AED - arc ED = 80 degrees

angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees
