Answer:

(x + 1)(x + 8)

Step-by-step explanation:

Given

x² + 9x + 8

Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (+ 9)

The factors are + 1 and + 8, since

1 × 8 = 8 and 1 + 8 = 9, thus

x² + 9x + 8 = (x + 1)(x + 8)

Answer:

Step-by-step explanation:

We know that

[tex]tan\theta =\frac{altitude}{base}[/tex]

Using this for the triangles

For the small triangle

[tex]tan \theta =\frac{6\frac{1}{2} }{9}[/tex]

[tex]\Leftrightarrow tan \theta =\frac{\frac{13}{2} }{9}[/tex]

[tex]\Leftrightarrow tan \theta =\frac{13} {18}[/tex]

Again for the bigger triangle

[tex]tan \theta =\frac{h}{31\frac{1}{2} }[/tex]

[tex]\Leftrightarrow tan \theta =\frac{h}{\frac{63}{2} }[/tex]

[tex]\Leftrightarrow tan \theta =\frac{2h}{63}[/tex]

Therefore

[tex]\frac{2h}{63} =\frac{13}{18}[/tex]

[tex]\Leftrightarrow h=\frac{13 \times 63}{18 \times 2}[/tex]

[tex]\Leftrightarrow h=\frac{819}{36}[/tex]

[tex]\Leftrightarrow h = 22.75[/tex] ft

Therefore h = 22.75 ft

After the second day of their road trip, the Murphy family has

9/20 or 45% of the total distance left to travel.

To solve this problem, let's denote the total distance of the trip as $D$.

On the first day, the Murphy family travelled 30% of the total distance, which can be written as:

[tex]\[ 0.30 \times D = \frac{30}{100} \times D = \frac{3}{10} \times D \][/tex]

On the second day, they travelled another 1/4 of the total distance, which is: [tex]\[ \frac{1}{4} \times D \][/tex]

The total distance travelled after two days is the sum of the distances travelled on the first and second days: [tex]\[ \frac{3}{10} \times D + \frac{1}{4} \times D \][/tex]

To add these fractions, we find a common denominator, which is 20:

[tex]\ total \ distance \ travelled =6/20D+5/20D[/tex]

[tex]\ total \ distance \ travelled =11/20D[/tex]

The remaining distance after the second day is:

Distance left=D−Total distance travelled

[tex]Distance \ left=D-11/20D[/tex]

[tex]Distance \ left=20/20 D-11/20D[/tex]

[tex]Distance \ left=9/20D[/tex]

Express the fraction and percentage of the distance left:

Fraction of the total distance left:

Fraction= Distance left/D

[tex]Fraction=9/20D/D=9/20[/tex]

After the second day, the Murphy family has 9/20 of the total distance left.​

Percentage of the total distance left:

Percentage= Distance left/D×100%

[tex]Percentage= 9/20D/D*100%[/tex]

[tex]Percentage=9/20*100%[/tex]

[tex]Percentage=45[/tex]

Therefore, after the second day of their road trip, the Murphy family has

9/20 or 45% of the total distance left to travel.

When x dissapears we have a false equation:

-4 = 5, so the equation does not have solutions, which means that Evelyn is incorrect.

The equation has infinite solutions?

Let's simplify the equation:

3(x - 3) + 5 = 3x + 1 + 4

distributing the left side.

3x - 9 + 5 = 3x + 1 + 4

3x - 4 = 3x + 5

If you subtract 3x in both we will get:

3x - 4 - 3x = 3x + 5 - 3x

-4 = 5

This is false, and x disappeared, so there is no value of x that makes this equation true, meaning that the equation does not have a solution.

Answer:

When you use 2 GB

Step-by-step explanation:

Data Plan a Formula 35(12p)

P = per GB

Data Plan B 25(17p)

Set each on equal to each other

Please Check my work, but I think this is on the right track.

The costs for both the data plans A and B will be the same for 2GB of data. The cost for each plan will be $59.

This problem is essentially asking us to find the number of gigabytes (GB) at which both data plans A and B cost the same. We can form two equations representing the costs of the plans. For plan A, the cost is $35 + $12 per GB. For plan B, the cost is $25 + $17 per GB. We can express these costs mathematically as: 35+12x=25+17x (where 'x' is the number of gigabytes). By solving this equation for 'x', we subtract 25 from both sides and also subtract 12x from both sides, which gives us 10 = 5x. Dividing by 5 from both sides give us x = 2 GB. So, for 2GB of data, the costs for both the data plans will be the same and the cost for each plan is $35 + 12(2) = $59 for plan A and $25 + 17(2) = $59 for plan B.

Answer:

x- intercept (- 8, 0), y- intercept (0, 8)

Step-by-step explanation:

To find the y- intercept, let x = 0 in the equation and solve for y

y = 0 + 8 = 8 ⇒ (0, 8 ) ← y- intercept

To find the x- intercept, let y = 0 in the equation and solve for x

x + 8 = 0 ( subtract 8 from both sides )

x = - 8 ⇒ (- 8, 0 ) ← x- intercept

X-intercept is (-8,0) and y-intercept is (0,8). the correct option is A.

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

We are given that;

Function y=x+8

Now,

The equation of the graph is y = x + 8. To find the x-intercept, we set y = 0 and solve for x.

0 = x + 8

x = -8

Therefore, the x-intercept is (-8, 0).

To find the y-intercept, we set x = 0 and solve for y.

y = 0 + 8

y = 8

Therefore, X-intercept will be (-8,0) and y-intercept will be (0,8).

Answer:

b)  Complement of spinning any number less than 3 is Spinning 3 or 4.

Step-by-step explanation:

COMPLIMENT of any Set A  is the set of all the elements which are in the  sample space but NOT IN SET A.

Here, Event E  = Spinning a spinner with 4 parts and getting a number less than 3.

Here, Sample Space = {1,2,3,4}

Also, as outcomes is LESS THAN 3, ⇒   E  = {1 ,2}  

Now, Compliment E  = Sample Space - { Elements in set E}

                                    = {1,2,3,4} -  {1 ,2}

or, E'  = { 3,4}

Hence,  complement of spinning any number less than 3 is Spinning 3 or 4.

Answer:

Spinning a 3 or 4

Step-by-step explanation:

The numbers that are less than 3 on the spinner, are 1 and 2. Therefore, the complement or opposite of that are all the numbers other than 1 and 2. So the answer is 3 and 4.

The police cruiser travels a total distance of 275.0 meters. It covers 137.5 meters during acceleration and the same distance during deceleration (in the opposite direction), summing up to 275.0 meters in total.

Calculating the distance covered during acceleration:

The equation for distance covered with constant acceleration is given by:

[tex]\[ s = ut + \frac{1}{2}at^2 \][/tex]

Where:

[tex]\( u \)[/tex] = Initial velocity

[tex]\( a \)[/tex] = Acceleration

[tex]\( t \)[/tex] = Time

Given:

Initial velocity [tex](\( u \))[/tex] = 20.0 m/s

Acceleration[tex](\( a \))[/tex] = 3.0 m/s²

Time[tex](\( t \))[/tex]= 5.0 seconds

Let's find the distance covered during acceleration using the above formula:

[tex]\[ s = ut + \frac{1}{2}at^2 \][/tex]

[tex]\[ s = (20.0 \, \text{m/s} \times 5.0 \, \text{s}) + \frac{1}{2} \times 3.0 \, \text{m/s}^2 \times (5.0 \, \text{s})^2 \][/tex]

[tex]\[ s = (100.0 \, \text{m}) + \frac{1}{2} \times 3.0 \, \text{m/s}^2 \times 25.0 \, \text{s}^2 \][/tex]

[tex]\[ s = 100.0 \, \text{m} + 37.5 \, \text{m} \][/tex]

[tex]\[ s = 137.5 \, \text{m} \][/tex]

Therefore, the distance covered during acceleration is 137.5 meters.

Calculating the distance covered during deceleration (slowing to a stop):

The cruiser starts at a speed of 20.0 m/s and decelerates uniformly until it comes to a stop. The distance covered during deceleration will be the same as the distance covered during acceleration but in the opposite direction.

So, the distance covered during deceleration = 137.5 meters (in the opposite direction).

Total distance traveled:

The total distance traveled by the cruiser during acceleration and then deceleration is the sum of these distances (taking the magnitudes):

Total distance = Distance during acceleration + Distance during deceleration

Total distance = 137.5 m + 137.5 m

Total distance = 275.0 meters

Therefore, the entire distance covered by the cruiser in the entire time is 275.0 meters.

Given, the chipmunks dropped an acron from the top of a tree. The acron was 0.25 kg and had a velocity of 4 m/s when it hit ground.

Kinetic energy =[tex]\frac{1}{2} m v^2[/tex]

Here m = 0.25 kg and v =4 m/s

Kinetic energy of the acron had =[tex]\frac{1}{2}\times 0.25 \times 4^2[/tex] J

                                                    = 2 J

The kinetic energy of the Chipmunk is 2 Joules.

Kinetic energy is the energy than an object possesses due to its motion. It is given by:

Kinetic Energy(KE) = (1/2)mv²

Where m is mass, v is velocity.

Given that m = 0.25 kg, v = 4 m/s, hence:

KE = (1/2)mv²

KE = (1/2) * 0.25 * 4² = 2J

The kinetic energy of the Chipmunk is 2 Joules.
