Help please I want to know how to solve for d
Answer:
Both the given angles are Vertically opposite and hence equal
So,
5d + 7 = 6d - 4
7 + 4 = 6d -5d
11 = d
The points Q, R, S and T all lie on the same line segment, in that order, such that the ratio of Q R : R S : S T QR:RS:ST is equal to 6 : 3 : 1. 6:3:1. If Q T = 10 , QT=10, find R S . RS.
RS = 3?
I will draw a diagram because its easier that way. If QS = 9 since 6 + 3 = 9 and QR = 6 then RS = 3 since 9 - 6 = 3.

Answer: [tex]12x^2+12xh+4h^2-2[/tex]
==================================================
Explanation:
First let's find the expression f(x+h). We replace every copy of x with x+h, expand, and simplify like so.
[tex]f(x) = 4x^3 - 2x\\\\f(x+h) = 4(x+h)^3 - 2(x+h)\\\\f(x+h) = 4(x+h)(x+h)^2 - 2(x+h)\\\\f(x+h) = 4(x+h)(x^2+2xh+h^2) - 2(x+h)\\\\f(x+h) = 4x(x^2+2xh+h^2)+4h(x^2+2xh+h^2) - 2(x+h)\\\\f(x+h) = 4x^3+8x^2h+4xh^2+4hx^2+8xh^2+4h^3 - 2x-2h\\\\f(x+h) = 4x^3+12x^2h+12xh^2+4h^3 - 2x-2h\\\\[/tex]
This may look ugly, but things will simplify a bit when we subtract off f(x)
Note how in f(x+h) we have the following terms
4x^3-2xWhich are the exact terms found in f(x) as well.
Why is this important? It helps us subtract and cancel. When we subtract off f(x), we cross off the 4x^3 and -2x terms in that f(x+h) equation above.
We'll be left with this
[tex]f(x+h)-f(x) = 12x^2h+12xh^2+4h^3-2h\\\\[/tex]
At this point, every term shown has at least one copy of 'h' as a factor.
This allows us to factor out h
[tex]f(x+h)-f(x) = h(12x^2+12xh+4h^2-2)\\\\[/tex]
Then we can divide both sides by h to get our final answer
[tex]\frac{f(x+h)-f(x)}{h} = \frac{h(12x^2+12xh+4h^2-2)}{h}\\\\\frac{f(x+h)-f(x)}{h} = 12x^2+12xh+4h^2-2\\\\[/tex]
----------------------------------------------------
Extra info:
h is nonzero to avoid dividing by zero. Though as h gets closer and closer to zero, terms with h in them will drop out since those terms will be very small. We'll be left with 12x^2-2. This is the derivative of f(x).
What are the roots of 4x2 + 35x − 9 = 0?
Answer:
Solution given:
4x²+35x-9=0
comparing above equation with ax²+bx+c.
we get
a=4
b=35
c=-9
we have
x=[tex] \frac{ - b±\sqrt{b²-4ac}}{2a} [/tex]
x=[tex] \frac{ - 35±\sqrt{35²-4*4*-9}}{2*4} [/tex]
x=[tex] \frac{ - 35±\sqrt{1369}}{2*4} [/tex]
x=[tex] \frac{ - 35±37}{8} [/tex]
taking positive;
x=[tex] \frac{ - 35+37}{8} [/tex]
x=[tex] \frac{1}{4} [/tex]
taking negative
x=x=[tex] \frac{ - 35-37}{8} [/tex]
x=-9
Therefore:the roots of 4x²+ 35x − 9 = 0 is [tex] \frac{1}{4} [/tex] or-9.

To save for retirement, you decide to deposit $1,000 into an IRA at the end of each year for the next 30 years. If this savings annuity has an interest rate of 10% per year compounded annually, then how much interest will you earn over the course of the 30 years?
Answer:
134494
Step-by-step explanation:
Answer: 134,494
Step-by-step explanation: d=$1,000, the yearly deposit.
r=0.10, or a 10% annual rate.
k=1, since we’re doing yearly deposits and we’ll compound yearly.
N=30, we want the amount after 30 years.
Putting this into the annuity formula:
PN=d⋅((1+rk)N⋅k−1)rkP30=1,000⋅((1+0.101)30⋅1−1)(0.101)P30=1,000⋅((1.1)30−1)(0.10)P30=1,000⋅(17.4494−1)(0.10)P30=1,000⋅(16.4494)(0.10)=$164,494.
The account will grow to $164,494 after 30 years.
Notice that you deposited into the account a total of $30,000 ($1,000 a year for 30 years). The difference between what you end up with and how much you put in is the interest earned. In this case it is $164,494–$30,000=$134,494.

Which statements are true about the lines of symmetry of a regular pentagon? Select three options
Complete question is;
Which statements are true about the lines of symmetry of a regular pentagon? Check all that apply.
A) Every line connects two vertices.
B) Every line connects the midpoints of 2 sides.
C) Every line bisects a vertex angle.
D) Every line bisects a side.
E) Every line is perpendicular to a side.
Answer:
C: Every line bisects a vertex angle.
D: Every line bisects a side.
E: Every line is perpendicular to a side.
Step-by-step explanation:
A shape will have a line of symmetry when after the perpendicular line is drawn through from one vertex to the centre of one side, it can be folded and the folded part will sit perfectly on top in such a way that all the edges match.
Now, a pentagon has 5 sides and by implication from the explanation of line of symmetry above, it has 5 lines of symmetry.
Attached below is an image showing the 5 lines of symmetry of a pentagon.
From the attached image, we can see that the lines of symmetry bisects a vertex angle, it bisects a side and is perpendicular to a side.
Thus correct answer is Options C, D & E

if angle CDE is a straight angle, DE bisects angle GDH, angle GDE=(8x-1), angle EDH= (6x+15), and angle CDF=43 , find each measure
The measures of the angle in the triangle are; ∠CDF = 43, ∠GDE = 63°, ∠FDG = 74°
How to find the measure of an angle?From the way the problem is worded:
∠CDE is a straight angle made up of three angles:
∠CDF = 43°
∠FDG is unknown
∠GDE = 8x - 1
∠EDH is outside CDE = 6x + 15.
DE bisects GDH to form GDE and EDH.
Thus, we have;
8x - 1 = 6x + 15
x = 8
Putting 8 for x, both angles are equal to 57°.
Since ∠CDF = 43 and ∠GDE = 63° and ∠CDE ∠ 180° in total.
∠FDG = 180° - 43° - 63° = 74°

If the missing data value were 32, the range would

If the missing data value were 50, the range of the
data would change substantially.
Answer:
Answer is D on e2020
Step-by-step explanation:
why does vla statistics have little to no answers available for it?
The statement that is correct is If the missing data value were 50, the range of the data would change substantially. The correct option is D.
What is the range of a data set?The range is the difference between the Maximum value of the data set and the Minimum value of the dataset.
Range = Maximum value of the data set - Minimum value of the dataset
The given data observation from the stemplot is given below.
8, 9, 9, 9, 10, 11, 12, 12, 12, 14, 15, 16, 16, 18, 18, 21, 22, 27, 27, 27, 31
Since IQR or the interquartile range is the difference between the quartiles, therefore, it won't be affected much if either of the two values 32 and 50 are added.
Now, the range of the data without 32 or 50 will be,
Range = 31 - 8 = 23
The range of the data when 32 is added,
Range = 32 - 8 = 24
The range of the data when 50 is added,
Range = 50 - 8 = 42
Hence, the statement that is correct is If the missing data value were 50, the range of the data would change substantially.

~~~PicklePoppers~~~Write an equation of the line passing through the point (-7,-6) that is parallel to the line y=3x+2
========================================================
Explanation:
Parallel lines have equal slopes but different y intercepts.
The slope of y = 3x+2 is m = 3 (compare it to y = mx+b)
Any parallel line will also have slope m = 3
The parallel line goes through (x1,y1) = (-7, -6)
--------------------
Turn to point-slope form. Plug in the values mentioned and solve for y
y-y1 = m(x-x1)
y-(-6) = 3(x-(-7))
y+6 = 3(x+7)
y+6 = 3x+21
y = 3x+21-6
y = 3x+15
---------------------
Or you could use slope intercept form
y = mx+b
y = 3x+b
-6 = 3(-7)+b
-6 = -21+b
-6+21 = b
15 = b
b = 15
Since m = 3 and b = 15, we know the equation is y = 3x+15
Rewrite in simplest terms: (3x + 2) + (-10x – 3)

produce per hour?
A=
B =
C =
Answer:
A = 112 , C = 85 , B = 90
Step-by-step explanation:
A + B + C = 287
A + C = 197
A + B = 202
C = 197 - A
B = 202 - A
A + 202 - A + 197 - A = 287
A = 112
C = 85
B = 90
Machine A, B and C can produce 112, 90 and 85 bolts per hour.
What is per hour ?Per hour defines 1 hour.When ever you see the word per second, per day means in 1 sec, 1 day.
According to the given question In a factory there are three machines, A, B and C.
When all three machines are working they can produce 287 bolts per hour.
∴ A + B + C = 287...(i)
When only A and C are working, they produce 197 bolts per hour.
∴ A + C = 197...(ii)
When only machines A and B are working, the produce 202 bolts per hour.
∴ A + B = 202...(iii)
Subtracting (ii) from (i) we get
B = 90.
Putting the value of B in (iii) we get
A = 112.
