Step-by-step explanation:

6c + 18-4c + 16

Solving like terms

2c + 34

Answer: 2c + 2

6(c + 3) - 4(c + 4)

= 6c + 18 - (4c + 16)

= 6c + 18 - 4c - 16

= 2c + 2

Answer:

[-9, 0]

Step-by-step explanation:

The range is the y values that the equation/line covers.

The line's lowest point is -9 and the line's highest point is 0. The values are defined (no open circle at the highest point) so we use brackets.

Answer:

6.03s

Step-by-step explanation:

Given the equation for the soccer ball's height, s, at time, t, seconds after the launch expressed as

s(t) = −4.9t2 + 19.6t +60

The ball hits the ground when s(t) = 0

Substitute s(t) = 0 into the expression

0= −4.9t2 + 19.6t +60

Multiply through by -10

0 = 49t²-196t-600

49t²-196t-600 = 0

Factorize

t = 196±√196²+4(600)(49)/2(49)

t = 196±√38416+117600/98

t = 196±√156016/98

t =196±394.99/98

t = 196+394.99/98

t = 590.99/98

t = 6.03secs

Hence the ball bit the ground after 6.03seconds later

Answer:

0.637 pounds per brick

Step-by-step explanation:

Given that:

A pickup truck carrying:

10³ identical brick weighs 6770 pounds

If the empty truck weighs  6133 pounds

The weight of each brick can be calculated as follows:

The weight of each brick = The weight of the full pick up truck - the weight of the empty truck

The weight of each brick = 6770 - 6133

The weight of each brick =  637

The pickup truck carrying 10³ identical brick = 1000 identical brick

Thus, the weight of each brick  = 637/10³

Thus, the weight of each brick  = 0.637 pounds per brick

Answer:

S = 32.1 m/s

Step-by-step explanation:

P = 1,500

S = 30

since P is proportional to S², then we must first determine S² = 900

900 / 1,500 = S² / 1,715

(900 x 1,715) / 1,500 = S²

1,543,500 / 1,500 = S²

S² = 1,029

S = √1,029 = 32.08 m/s ≈ 32.1 m/s

Answer:

Yeh that's what you have to do.....

Divide the total amount by four

Answer:

yes

Step-by-step explanation:

Step-by-step explanation:

For them to owe you a total of$2000 then an interest of $2000-320=$1680 must have accrued over the time T

T=$1680×100/320×11

T=47.7272...≈47.73 to the nearest hundredth

Proof,

Interest after 47.7262...years which is converted to 525/11 years

=($320×11×525/11)/100

=$1680

therefore total amount which will be owed at that time =principal+interest accrued

=$320+1680=$2000

Answer:

1.2 miles in 24 minutes

Step-by-step explanation:

3 miles per hour = .05 miles per minute

24 x 0.05 = 1.2

Remember that speed is defined as the rate of change of the position respect to the time, thus we can define the relation:

Distance = Spee*Time.

Using this we will get the solution: distance = 1.2 miles

Let's see how to get the solution:

We start with the given information:

So we got a time and we also have a speed, but the time units in these are different.

So knowing that:

1 hour = 60 minutes

(1 hour/60 minutes) = 1

Then we can write:

24 minutes = (24 minutes)*(1 hour/60 minutes) = 0.4 hours

Then we have:

time = 0.4 hours

speed = 3 miles per hour.

Then, using the first equation, we get:

distance = (3 miles per hour)*0.4 hours = 1.2 miles.

Answer: No. Nicolas is wrong.

Step-by-step explanation:

The formula for calculating nth term of a geometric sequence is given as:

= ar^n-1.

where a = first term = 15

r = common ratio = 30/15 = 2

n = 13

Using the formula,

= ar^n-1

= 15 × 2^(13-1)

= 15 × 2^12

= 15 × 4096

= 61440

The 13th term is 61440. Nicolas is wrong.

Answer:

Step-by-step explanation:

4x + 23 > -21

4x > -21 -23  (moving 23 to the right side of equation changes the +23 to  -23

4x > -44  (adding -21 to -23)

x > -11  (dividing both sides of equation by 4, this keeps the equation the same

Solution:  x > -11  (x is greater than negative 11)
