Answer:
1/4 b^9
Step-by-step explanation:
(b^11 b^-7)/4b^-5
We know x^y * x^z = x^(y+z)
b^11 * b^ -7 = b^ (11-7) = b^4
(b^11 b^-7)/4b^-5
b^4 / 4 b^-5
We know x^y / x^z = x^(y-z(
b^4 / b^-5 = b^(4 - -5) = b^(4+5) = b^9
1/4 b^9

Can you guys help me find ST on the left and WY on the right
Answer:
ST = 17 and WY = 32
Step-by-step explanation:
3
SV is a perpendicular bisector and divides Δ RST into 2 congruent triangles with
ST = SR , that is
7x - 4 = 3x + 8 ( subtract 3x from both sides )
4x - 4 = 8 ( add 4 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Then
ST = 7x - 4 = 7(3) - 4 = 21 - 4 = 17
-------------------------------------------------------------------
4
Δ WXY and Δ WXZ are congruent ( both have 3 congruent angles ), then
WZ = WY , that is
9x - 13 = 6x + 2 ( subtract 6x from both sides )
3x - 13 = 2 ( add 13 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
WY = 6x + 2 = 6(5) + 2 = 30 + 2 = 32

Rewrite the expression in the picture in the form k times x^n.
Answer:
8 x^-2
Step-by-step explanation:
2 sqrt(x) * 4x ^ -5/2
Rewriting
2 x^1/2 * 4x ^ -5/2
2*4 = 8
x^1/2 * x^ -5/2
We know a^b * a^c = a^(b+c)
x^ 1/2 * x^ -5/2 = x^ (1/2 -5/2 ) = x^ (-4/2) = x^-2
8 x^-2

Answer:
#1 is f.
#2 is d.
#3 is a.
#4 is b.
#5 is c.
#6 is g.
#7 is e.
Step-by-step explanation:
The digit "9" is in the ten's place because it is two numbers/spaces left from the decimal. If you make all the other digits "0", you'll be left with a value of 90.
The digit "1" is in the one's place because it is one number/space left from the decimal. Applying the same concept of making all the other digits "0", you'll be left with a value of 1.
The type of digits to the right of the decimal, starting from left to right, are the tenths place, hundredths place, thousandths place, ten-thousandths place, and millionths. Remember and know those digit types based on their position away from the decimal. The value will be there for you to see afterward.

Answer:
3.8; 4
Step-by-step explanation:
In this exercise, you're are required to find the missing values by performing some arithmetic calculations.
For the first part;
Let the missing value be X
Translating the word problem into an algebraic expression, we have;
[tex] X = 2000 * 1.9 * 10^{-6} [/tex]
[tex] X = 3.8 * 10^{-3} [/tex]
For the second part;
Let the missing value be Y.
[tex] 3.8 * 10^{-3} = Y * 9.5 * 10^{-4} [/tex]
[tex] X = \frac {3.8 * 10^{-3}}{9.5 * 10^{-4}} [/tex]
[tex] X = 4 [/tex]
Therefore, the complete sentence would be written as follows;
[tex] 3.8 * 10^{-3} [/tex] is 2000 times greater than [tex] 1.9 * 10^{-6} [/tex]. It is also 4 times greater than [tex] 9.5 * 10^{-4} [/tex]
m∠A = (2x + 5)° and m∠B = (3x − 15)°.
Find the measure of each angle (in degrees) of ▱ABCD.
Answer:
Step-by-step explanation:
We have to assume that ABCD is a parallelogram. If it isn't, leave a note.
Secondly we have to assume that the angles are consecutive. In a parallelogram, consecutive angles are supplementary.
<A + <B = 180
2x + 5 + 3x - 15 = 180
5x - 10 = 180 Add 10 to both sides
5x = 190 Divide by 5
x = 190/5
x = 38
A = 2x + 5
A = 2*38 + 5
A = 81
B = 3x - 15
B = 3*38 - 15
B = 99
write the next 3 numbers in this pattern. Then describe the rule for this pattern in an nth expression.
11 , 101 , 1001 , 10001,…
Answer:
An=10^n + 1 is the expression for the nth term.
Next three terms:
100001
1000001
10000001
Step-by-step explanation:
The number ot 0's imcrease between the two 1's starting at no zeros, 1 zero, two zeros, and so on...
So the next terms are 100001, 1000001, 10000001 and that's without finding the formula.
Now let's find the formula:
A1=11=10+1
A2=101=100+1
A3=1001=1000+1
Notice we have increasing powers of 10 and then just adding 1.
A1=10^1 +1
A2=10^2 +1
A3=10^3 +1
....
An=10^n +1

Mrs.Click has a strawberry patch in her garden. It's border is 4/5 meters wide and 3/2 meters long. What is the area of Mrs.Clicks Garden?
Answer
Mrs. Click's Garden is 6/5 or 1 1/5 square meters.
Explanation
Mrs. Click's has a rectangular garden. To find the area of a rectangle, you multiply the width by the length. To find the area of Mrs. Click's Garden, you multiply 4/5 by 3/2.
To multiply fractions, you multiply the numerator by the denominator.
4×3 is 12 and 5×2 is 10. You get the fraction 12/10, which can be simplified to 6/5, or 1 1/5.

Which of the following quadrilaterals must be a parallelogram according to the minimum requirements?
The minimum requirements needed to be a parallelogram is found in Option A quadrilateral, thus Option A is our correct answer.
There are four quadrilaterals given in the option.
We need to check which quadrilateral has the minimum requirements.
What is the minimum requirement to construct a parallelogram?The construct a Parallelogram we need:
- The measure of any two non-parallel sides.
- The measure of an angle.
In a Parallelogram, opposite sides are equal and parallel and the opposite angles are equal.
Checking the options given.
Option A:
- Two parallel and equal sides.
- Equal opposite angles.
It meets the minimum requirement to be a parallelogram.
Option B:
The quadrilateral has only two parallel and equal sides.
It does not meet the minimum requirements to be a parallelogram.
Option C:
The quadrilateral has only one parallel and equal side.
It does not meet the minimum requirements to be a parallelogram.
Option D:
It has no parallel and equal sides.
It has equal opposite angles and diagonal bisecting.
But it does not meet the minimum requirements to be a parallelogram.
We see that the minimum requirements needed to be a parallelogram is found in option A,
Hence Option A is our correct answer.

d²y/dx²=12x-12. express y in terms of x
Answer:
y(x)=2x^3-6x^2+ax+b, a and b are constants
Step-by-step explanation:
d2y/dx2=12x-12, integrating both sides we get
dy/dx=6x^2-12x+a, where a is the integration constant.
Again integrating both sides, we get
y(x)=2x^3-6x^2+ax+b, where b is the integration constant
What is the value of x in the equation 8x – 2y = 48, when y = 4?
Answer:
x = 7
Step-by-step explanation:
since we know y = 4, we can plug this into the equation to find x
8x - 2y = 48
8x - 2(4) = 48
8x - 8 = 48
8x = 56
x = 7
Answer:
x=7
Step-by-step explanation:
8x – 2y = 48
Let y=4
8x - 2(4) = 48
8x - 8 = 48
Add 8 to each side
8x -8+8 = 48+8
8x = 56
Divide each side by 8
8x/8 = 56/8
x = 7

When the focus and directrix are used to derive the equation of a parabola, two distances were set equal to each other. = StartRoot (x minus x) squared + (y minus (negative p)) squared EndRoot = StartRoot (x minus 0) squared + (y minus p) squared EndRoot The distance between the directrix and is set equal to the distance between the and the same point on the parabola.
Answer:
The answer is "A point on the parabola and Focus".
Step-by-step explanation:
[tex]= \sqrt{(x - x)^2 + (y- (-p))^2} = \sqrt{(x-0)^2+ (y-p)^2} \\\\= \sqrt{(0)^2 + (y+p))^2} = \sqrt{(x)^2+ (y-p)^2} \\\\= \sqrt{(y+p))^2} = \sqrt{(x)^2+ (y-p)^2} \\\\= (y+p) = (x)+ (y-p) \\\\= y+p = x+ y-p \\\\=2p=x\\\\=x=2p[/tex]
Whenever the focus and also the guideline are utilized in determining the parabolic formula, two distances have indeed been equal.
The distance from the direction, as well as a parabolic point, was equal to the distance from the center to a parabolic point.
Answer:
The distance between the directrix and a point on the parabola is set equal to the distance between the focus and the same point on the parabola.

Answer:
31 degrees
Step-by-step explanation:
the side with the length of 29 can be seen as the radius of a circle.
and the sin value of an angle is the distance of a point on that circle from the x-axis. as the standard sin function is for the standard circle with radius 1, we need to multiply this by the actual radius.
15 = sin(?)×29
sin(?) = 15/29 = 0.5172...

mary has 17 m of rope. She wishes to cut it in three pieces so that she has 3 m more than amanda, and amanda has 2 m less than Sarah.
Answer:
Length of Sarah rope = 6 m
Length of Amanda's rope = 4 m
Length of Mary's rope = 7 m
Step-by-step explanation:
Let the length of Sarah rope = x
Length of Amanda's rope= x - 2
Length of Mary's rope = (x - 2 ) + 3 = x - 2 + 3 = x + 1
Length of rope = 17 m
x + x - 2 + x + 1 = 17
Combine like terms
x + x + x - 2 + 1 = 17
3x - 1 = 17
Add 1 to both sides
3x = 17 + 1
3x = 18
Divide both sides by 3
x = 18/3
x = 6
Length of Sarah rope = x = 6 m
Length of Amanda's rope= x - 2 = 6 - 2 = 4 m
Length of Mary's rope = x + 1 = 6 + 1 = 7 m

If two triangles have three congruent, corresponding angles, what additional information is needed to prove that the triangles are congruent?
Answer:
one side length has to be equal in both triangles.
Answer:
To prove that two triangles with three congruent, corresponding angles are congruent, you would need to have at least one set of corresponding sides that are also congruent. You could then use ASA or AAS congruence theorems or rigid transformations to prove congruence.
