Answer:

Step-by-step explanation:

as x+6 is the quotient, you need to use -6

-6 |  4   -3   +5       6

x         -24  +162 -1002

add

       4  -27  167  -996

f(x)= 4x^2 -27x +167 - 996/(x+6)

Lets check

(x+6)(4x^2 -27x +167)= 4x^3 -27x^2 +167x + 24x^2 - 162x + 1002 =

= 4x^3 - 3x^2 +5x +1002

1002-996= 6

So we have the correct solution: 4x^2 -27x +167 - 996/(x+6)

[tex](x+11)(x-7)[/tex]

Step-by-step explanation:

To factorize [tex]x^2+4x-77[/tex]

[tex]\textsf{for} \ ax^2+bx+c \ \textsf{find} \ v, w \ \textsf{such that} \ v \cdot w=a \cdot c \ \textsf{and} \ v+w=b\\ \textsf{ and group into} \ (ax^2+vx)+(wx+c)[/tex]

[tex]a \cdot c=1 \cdot -77=-77[/tex]

[tex]b=4[/tex]

Therefore, the 2 numbers that multiply together to give -77 and add together to give 4 are:  11 and -7

[tex]\implies x^2+11x-7x-77[/tex]

[tex]\implies (x^2+11x)+(-7x-77)[/tex]

Factor the parentheses:

[tex]\implies x(x+11)-7(x+11)[/tex]

Factor out the common term [tex](x+11)[/tex]:

[tex]\implies (x+11)(x-7)[/tex]

[tex]\\ \rm\rightarrowtail x^2+4x-77[/tex]

[tex]\\ \rm\rightarrowtail x^2+11x-7x-77[/tex]

Answer:

After the December 7, 1941, Japanese attack on the American naval fleet at Pearl Harbor, Hawaii, the U.S. was thrust into World War II (1939-45), and everyday life across the country was dramatically altered. Food, gas and clothing were rationed. Communities conducted scrap metal drives. To help build the armaments necessary to win the war, women found employment as electricians, welders and riveters in defense plants. Japanese Americans had their rights as citizens stripped from them. People in the U.S. grew increasingly dependent on radio reports for news of the fighting overseas. And, while popular entertainment served to demonize the nation’s enemies, it also was viewed as an escapist outlet that allowed Americans brief respites from war worries.

Step-by-step explanation:

The interest rate Cindy will be charged is approximately 8.5%.

The money factor or lease factor is a method for determining the financing charges on a lease with monthly payments. The money factor can be translated into the annual percentage rate (APR) by multiplying the money factor by 2,400.

Money factor = 0.00354

So, the interest rate Cindy will be charged = 2400* 0.00354

The interest rate Cindy will be charged = 8.496% ≈8.5%

Therefore, The interest rate Cindy will be charged is approximately 8.5%.

Answer:

-15 meters

Step-by-step explanation:

Elevation means the height to which something is elevated. If the object is above sea level then it is positive. If the object is below sea level it is negative.

The elevation of the surface of the ocean is, - 15 meters.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A fish is 15 meters below the surface of the ocean.

Here, The fish is 15 meters below the surface of the ocean.

Hence, Its elevation shows in negative sign.

Thus, We get;

The elevation of the surface of the ocean = - 15 meters.

Given :

Casey's company charges , C = $300.

In summer special, Casey offers customers a trade discount of 25%.

To Find :

Charges during summer.

Solution :

Let, x is the amount of charges they take during summer.

Casey offers customers a trade discount of 25%.

[tex]x =300(1-\dfrac{25}{100})\\\\x=300(1 - 0.25)\\\\x=300(0.75)\\\\x=\$225[/tex]

Therefore, amount of charges during summers are $225.

Hence, this is the required solution.

The speed of the boat will be 12.18 mph, and the angle of its direction measured from the positive x-axis will be 224.3°

First, let's define North as the positive y-axis and east as the positive x-axis.

In this coordinate axis, the angle S 60° W is equal to 210°.

Then the velocity of the boat will be:

v = (17mph*cos(210°), 17mph*sin(210°))

Now we also need to add the speed of the river, which is 6mph to the east, then the final velocity of the boat will be:

v = (17mph*cos(210°) + 6mph, 17mph*sin(210°))

v = (-8.72mph, -8.5 mph)

Then the speed of the boat will be:

|v| = √( (-8.72mph)^2 + (-8.5 mph)^2)  =12.18 mph

And the angle, measured from the positive x-axis, will be given by the arctangent of the quotient between the y-component and the x-component:

Atan(-8.5 mph/-8.72mph) = 224.3°

How high the football gets is a function of the maximum height of the ball

The football goes 40.313 ft high

The equation that models the height of the ball is given as:

[tex]h(t) = -5t^2 +27.5t+2.5[/tex]

Differentiate the function

[tex]h'(t) = -10t +27.5[/tex]

Set to 0

[tex]-10t +27.5 = 0[/tex]

Collect like terms

[tex]10t =27.5[/tex]

Divide by 10

[tex]t =2.75[/tex]

Substitute 2.75 for t in [tex]h(t) = -5t^2 +27.5t+2.5[/tex] to calculate how high the ball get

[tex]h_{max} = -5 * 2.75^2 +27.5 * 2.75+2.5[/tex]

[tex]h_{max} = 40.3125[/tex]

Answer:

slope is 3/2

Step-by-step explanation:

you can find slope by comparing the vertical height / horizontal height of two points on the line

for example, we can use points (20,0) and (40,30)

vertical height is 30 minus 0 which is 30

horizontal height is 40 minus 20 which is 20

so slope is 30/20 or 3/2
