Inequality Form:

x>-11

Step-by-step explanation:

Interval Notation:

(-11,\infty )

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)

Answer:

Step-by-step explanation:

5x+2=4x-9  -4x from both sides

x+2=-9 take 2 from both sides

x= -11

Answer:

x = -11

Step-by-step explanation:

5x + 2 = 4x - 9

5x = 4x - 11

x = -11

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

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:

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:

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.

Step-by-step explanation:

The magnitude and direction angle of c is 12.8 and 128.7° respectively.

"A vector contains two types of information: a magnitude and a direction. The magnitude is the length of the vector while the direction tells us which way the vector points.

Vector direction can be given in various forms, but is most commonly denoted in degrees. Acceleration and velocity are examples of vectors."

Given: a = (5, –9) and b = (–3, 1) and c = b – a.

Therefore, c = (5+3, -9-1) = (8, -10)

Now, magnitude of c is [tex]\sqrt{8^{2}+(-10)^{2}}[/tex] = 12.8

The direction of c is Ф = tan⁻¹(-10/8) = -51.3°

Therefore, the direction of c is 180° - 51.3° = 128.7°  (tanФ = tan(π+Ф))

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
