Step-by-step explanation:

Answer:

x = 13

Step-by-step explanation:

4(x-3)=40

4x - 12 = 40

4x = 40 + 12

4x = 52

x = 13

-The leading coefficient is -2.

-The degree of the polynomial is 7.

-The constant term is 4.

Step-by-step explanation:

A polynomial is an expression which has many terms. Each term is separated by addition or subtraction. The standard form of a polynomial is and is written in descending order by exponent. The highest exponent is known as the degree of the polynomial. The leading term at the beginning has a leading coefficient.

Using the information above, select what applies for -2xy^5+3x^7-10x^3y^6+8x^6+4.

-The polynomial has 5 terms.

-The leading coefficient is -2.

-The degree of the polynomial is 7.

-The constant term is 4.

-The polynomial is in decreasing degree order.

Answer:

30 and 33 years

Step-by-step explanation:

Let Lara be x years

Cam =x+3

x+x+3=63

2x+3=63

2x=63-3

2x=60

x=60/2

x=30

Lara=30years and Cam =30+3+33years

Answer:

Lara 30 years, Cam 33 years

Step-by-step explanation:

denote x being the age of Lara

denote y being the age of Cam

Cam is 3 years older than Lara, so

y = x + 3

their combined age is 63 so

x + y = 63.

solving can be done by plugging in y = x+3, then

x + (x+3) = 63, which gives x = 30.

So Lara is 30 years.

Cam is 3 years older, so Cam is 33 years

a) y = 2(3) + 5

b) y = 6 + 5

c) y = 11

2. find g(2) = 3x² + 2x + 5

a) y = 3(2)² + 2(2) + 5

b) y = 3(4) + 4 + 5

c) y = 12 + 4 + 5

d) y = 21

3. add f(3) + g(2)

a) 11 + 21

b) = 32

Answer:

m=-4 slope is -4

Step-by-step explanation:

The centroid (the point where the medians meet) divide each median into parts with lengths in a ratio of 2:1. This means 7x + 1 is twice the length of 3x + 4, or

7x + 1 = 2 (3x + 4)

Solve for x :

7x + 1 = 6x + 8

7x - 6x = 8 - 1

x = 7

Then XE has length

XE = 4•7 - 2 = 28 - 2 = 26

FX is twice this length, so

FX = 2•26 = 52

and so FE has length

FE = FX + XE = 52 + 26 = 78

Answer:

The Answer is 850$

Answer:

It will travel 213.2 miles.

Step-by-step explanation:

Multiply 41 by 5.2

There are 213.2 miles a car travel with an average of 41 mph in 5.2 hours.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

An average speed of a car = 41 mph

And, Time taken by car = 5.2 hours

We know that;

⇒ Speed = Distance / Time

Substitute all the values, we get;

⇒ 41 = Distance / 5.2

⇒ Distance = 41 × 5.2

⇒ Distance = 213.2 miles

==========================================

Explanation:

AB is a diameter of the circle with point O in the center. This makes angle AOB to be 180 degrees. Consequently, arc ADB makes up 180 degrees of a full 360 degree circle (ie it makes up half of the circle since 180/360 = 1/2)

We're told that arc ADB is 15pi units long. Since arc ADB makes up half the circle, the full circle must therefore be 2*15pi = 30pi. This is the circumference.

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

We're also told that angle COB is 60 degrees. Let's find angle COA

(angleCOA) + (angleCOB) = 180

angleCOA = 180-(angleCOB)

angleCOA = 180-60

angleCOA = 120

Angle COA is 120 degrees

This makes up 120/360 = 1/3 of the full circle

So (1/3)*(circumference) = (1/3)*(30pi) = 10pi is the arc length of AC where we take the shorter path from A to C along the circle's edge.

Answer:

AC = 10π

Step-by-step explanation:

Consider arc ADB with length 15π

ADB = circumference of circle × fraction of circle , that is

2πr × [tex]\frac{180}{360}[/tex] = 15π

2πr × [tex]\frac{1}{2}[/tex] = 15π

πr = 15π ( divide both sides by π )

r = 15

∠ AOC = 180° - 60° = 120° ( adjacent angle to 60° )

Thus

AC = 2πr × [tex]\frac{120}{360}[/tex]

     = 2π × 15 × [tex]\frac{1}{3}[/tex]

     = 30π × [tex]\frac{1}{3}[/tex]

     = 10π
