Hi. Please i need help with this . No jokes . I need help with (vii) and (ix)
Answers
9514 1404 393
Answer:
(vii) 25/4
(ix) -61/6
Step-by-step explanation:
(vii) Once again, we remind you that for ax²+bx+c=0, ...
α+β = -b/a = -(-7/2) = 7/2 = 3.5
αβ = c/a = -3/2 = -1.5
Then the desired expression is ...
α/(β+1) +β/(α+1) = (α² +α +β² +β)/((α+1)(β+1))
= ((α+β)² -2αβ +(α+β))/(αβ +(α+β) +1)
= (3.5² -2(-1.5) +3.5)/(-1.5 +3.5 +1) = 18.75/3 = 6.25 = 25/4
__
(ix) α/β +β/α = (α²+β²)/(αβ)
= ((α+β)² -2αβ)/(αβ) = (3.5² -2(-1.5))/-1.5 = 15.25/-1.5 = -61/6
Simplify (4x – 6) + (5x + 1).

The Smith family took out a $160,000 loan. After 30 years they had paid a total of 364000. What is the interest rate on the loan? Can someone pls answer this in an hour using the equation Interest= principal x rate x time.
Answers
Answer:
The interest rate is 0.0425%
Step-by-step explanation:
Mathematically;
I = PRT/100
From the question, I in this context is the difference between how much they have paid and the amount borrowed
Mathematically, this is ; 364,000-160,000 = 204,000
This is the interest
R is the rate = ?
T = 30 years
P is the amount borrowed = 160,000
thus, we have
204,000 = (160,000 * R * 30)/100
2040 = 4800000R
R = 2040/4800000
R = 0.000425 which is 0.0425%

what is a term called that has no variable? constant or coefficient
Answers
Answer: It is constant
Answer:
Constant.
Step-by-step explanation:
Constants are any number that does not have a variable such as x or y, so if they do not have variables, there definitely would not have coefficients. Examples of constants are 2, 5 and 67.
Coefficients are like the 2 in 2x, the 5 in 5y and the 67 in 67xy. All of these numbers have a variable.

I think this means to find the mid-point(?) of the line which by doing that you take both x-values and you add them and then divide by two, and then you take both y-values and add them and then divide by two. So you have: (1+-4)=-3, (-3/2)=-1.5
-1.5=x
(2+-2)=0, (0/2)=0
0=y
(-1.5, 0)

Answer:
you can create your box plot from the following answers
a) minimum = 13
b) first quartile = 17
c) median = 22.5
d) third quartile = 26.5
e) maximum = 32
e) interquartile range = 26.5 - 17 = 9.5
Step-by-step explanation:
minimum and maximum values are self-explanatory
first quartile is derived by getting the median of the lower half of data (the median will divide the data into the lower half and the upper half)
third quartile is derived by getting the median of the upper half of data
the median is sometimes referred to as the second quartile
box plots are all about quartiles so that you can see where 25% of the data reside, or 50% or 75%, etc

The floor of a new planetarium is a circle with a 13-yard diameter.A stage will occupy a quarter circle section of the floor.The material for the stage will cost $31.47 per square yard. If no material is wasted when making the stage,how could you find how much the stage will cost? Use 3.14
Answers
Answer:
$1,043.74Step-by-step explanation:
Area of the circular floor = πr²
Since the stage only occupies a quarter circle section of the floor, then;
Area of the stage = πr²/4
Given
diameter of the floor = 13yd
radius = 13/2 = 6.5yd
Find the area of the stage;
Area of the stage = π(6.5)²/4
Area of the stage = 3.14(42.25)/4
Area of the stage = 33.16625yd²
If the material for the stage will cost $31.47 per square yard, this means;
1yd² = $31.47
33.16625yd² = x
Cross multiply
x = 33.16625*31.47
x = 1,043.74
Hence the stage will cost $1,043.74

Answers
Answer:
Step-by-step explanation:
Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;
The standard equation of a line is y = mx+c
m is the slope
c is the intercept
Get the slope;
m = Δy/Δx = y2-y1/x2-x1
m = -10-(-3)/7-6
m = -10+3/1
m = -7
Get the intercept;
Substitute the point (6, -3) and m = -7 into the expression y = mx+c
-3 = -7(6)+c
-3 = -42 + c
c = -3 + 42
c = 39
Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c
y = -7x + 39
Hence the required equation is y = -7x + 39
