The polynomial 2x³ + qx² + rx + 2 has a
factor (x - 1) and leaves a remainder of
12 when divided by (x - 2). Find the
constants q and r and hence the other
factors of the polynomial.
Answer:
q = 1 , r = -5
other factors of polynomial:
(2x - 1) & (x + 2)
Step-by-step explanation:
In the first part, substitute x = 1 make it equal to 0.
Substitute x = 2 and make it equal to 12.
Rearrange both, until you have two linear equations.
Solve the set of simultaneous equation to find q and r .
Second part place the value of q and r to have the full polynomial.
Carry out long division, dividing the polynomial by the factor that's stated in the question (x - 1) and you will have a quadratic equation.
Factorise the quadratic equation to have the two other factors of the polynomial.

5. After t seconds, a ball tossed in the air from the ground level reaches a height
of h feet given by the function h(t) = 144t – 16t^2. PART A: What is the height of
the ball after 3 seconds? PART B: After how many seconds will the ball hit the
ground before rebound? -
Answer:
a = 288 feet, b = 9 seconds
Step-by-step explanation:
t = 3, solve for h(t)
h(3) = 144(3)-16(3)^2
=432-144
=288
H(t) = 0, solve for t
0=144(t)-16(t)^2
t = 0, t =9

Three angles are complementary. One angle is double the smallest angle. The largest angle is
triple the smallest angle. Find the measures of
the three angles.
Answer:
Step-by-step explanation:
A+B+C = 90°
A ≤ B ≤ C
C = 3A
B = 2A
A+B+C = A + 2A + 3A = 6A = 90°
A = 15°
B = 2A = 30°
C = 3A = 45°

what is the value of x , where
2x + 1 = 99
Answer:
x=49
Step-by-step explanation:
2x+1=99
2x=98
x=49
Answer:
To find the value of x we need to solve this equation
2x + 1 = 99
now ,taking constant to right side
2x = 99 - 1
2x = 98
x = 98/2
x= 49

4x + 5y = 22
7x - 3y = -32
Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ 35x - 15y = -160
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6

(7 + 190). -15 =
(x + 1). 14=
Answer:
6(1-5m) = 6 − 30 m
3(4+3r) = 12 + 9 r
3(6r+8) = 18 r + 24
4(811+ 1+2) = 3256
-(-2-n) 7) = 14 + 7 n
-6(7k+11) = − 42 k − 66
-3(71+1) = − 216
-6(1 +116) = − 702
-10(a - 5) = − 10 a + 50
-3(1 + 2v) = − 3 − 6 v
-4(3r+2) = − 12 r − 8
(3 - 76)-2 = − 75
(-2018x+20) = − 2018 x + 20
(7 + 190)-15 = 182

Two rovers are exploring a planet. The system of equations below shows each rovers elevation y at time x.
Given right triangle ABC with altitude BD is drawn to hypotenuse AC. If AB=5 and AD=1, what is the length of AC ? (Note: the figure is not drawn to scale.)
Answer:
x = 24.99 or 25
Step-by-step explanation:
Using sin to figure out the angle of ABD, we can figure out the angle of CBD by subtracting it from 90°.
sin y = (1/5)
y = 11.54°
90 - 11.54 = 78.46°
Now using Pythagorean Theorem (a²+b²=c²) we can solve for line BD.
1² + b² = 5²
1 + b² = 25
b² = 24
b = √24
Now we can use tan to figure out the length of segment DC.
tan(78.46) = z/√24
z = 23.99
We can now combine the known length of segment AD and the length of DC to get x.
1 + 23.99 = 24.99 or about 25.

5.A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.
What was the average speed of the train for the entire journey?
Round to the nearest tenth, if necessary.
52.0 mi/h
56.0 mi/h
56.7 mi/h
60.0 mi/h
Answer:
Step-by-step explanation:
The key for this assignment is look at the units and values given. What is the desired units/value? You could also use d = r*t assuming a constant rate.
1.) If you look at the units for distance and time, and you know you want m/s for speed, then you can see division would be solution.
d = rt
40 = r(10)
r = 40/10
2.) d = rt
425 = (50)t
t = 8.5s
3.) d = rt
d = (35.25)(4)
d = 141km
4.) Add the distances together by using the equation twice for the way there and back.
216 = (48)t
t = 4.5
216 = (54)t
t = 4
4.5 + 4 = 8.5 hours
5.) Do the same thing from problem number four
210 = r(3.5)
r = 60m/h
130 = r(2.5)
r = 52mi/h
Average means the sum of the values divided by 2
0.5(60+52) = 56mi/h

9.16 rounded to the nearest hundredth
Answer:
9.20
Step-by-step explanation:
9.12 because 6 rounded to nearest hundredth is 10 and that is a whole number. You also already know that 16 is a higher number than ten so it would be rounded to 20 or in this case 2. Hope this helps :)

The sum of 4 consecutive integers
is 354
Consecutive integers are numbers in a row on a number line (ie. 4,5,6 or 457,458,459 or 12341, 12342, 12343). They can also be negative as long as the problem doesn't specify if it's positive.
x= first integer
x+1= second integer
x+2= third integer
x+3= fourth integer
Add the four integers equal to 354.
x + (x+1) + (x+2) + (x+3)= 354
combine like terms
4x + 6= 354
subtract 6 from both sides
4x= 348
divide both sides by 4
x= 87 first integer
THREE REMAINING INTEGERS
x+1= 87 + 1= 88 second integer
x+2= 87 + 2= 89 third integer
x+3= 87 + 3= 90 fourth integer
ANSWER: The four consecutive integers are 87, 88, 89 and 90.
