solve ax^2-c=0 assume a and c are positive
9514 1404 393
Answer:
x = ±√(c/a)
Step-by-step explanation:
Undo what is done to x.
ax² -c = 0
ax² = c . . . . . . add c
x² = c/a . . . . . . divide by a
x = ±√(c/a) . . . . take the square root

Will you need to show that all of the parts of one triangle are congruent to all of the parts of the other triangle to prove they are congruent? Explain.
Answer:
will be sufficient to prove triangles congruent. If three sides of a triangle are congruent to three sides of another triangle, the triangles are congruent. If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
Find the slope of the line that passes through the points (-6,-2) and (-7,2)
Answer:
-4
Step-by-step explanation:
the steps are in the pic above
Item 1
Use the figure to find the measures of the numbered angles.
Parallel lines a and b are intersected by a transversal t. Angle 1 and angle 99 degrees are supplementary angles. Angle 1 and angle 3 are vertical angles. Angle 2 and angle 99 degrees are vertical angles. Angle 99 degrees and angle 4 degrees are corresponding angles on the same side of the transversal. Angle 1 and angle 5 are corresponding angles on the other side of the transversal. Angle 5 and angle 7 are vertical angles. Angle 6 and angle 4 are vertical angles.
9514 1404 393
Answer:
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Step-by-step explanation:
Vertical and corresponding angles are congruent. Angles 1 and 99° are supplementary, so ...
∠1 = 180° -99° = 81°
Then we have ...
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°

Tessellations
Determine whether the given figure tessellates the plane.
a. yes
b. no
Please select the best answer from the choices provided
Answer:
A. Yes
Step-by-step explanation:
I calculated it logically
Yes the given figure with rectangle tessellates the plane.
A rectangle cannot tessellate a plane by itself because it is not a regular polygon with equal angles and sides.
A rectangle can only tessellate the plane if it is combined with other shapes, such as squares or triangles, to form a regular tessellation.
Yes, the given figure tessellates the plane.
Hence, Yes the given figure tessellates the plane.

Jennifer wants to borrow $ 20, 000 . Her bank offers a 7.1% interest rate. She can afford $500 a month for loan payments. What should be the length of her loan to the nearest tenth of a year
Answer:
4.2 years
Step-by-step explanation:
20000(.071)t ≤ 500(12)
1420t ≤ 6000
t = 4.2
Her loan is 4.2 years long to the nearest tenth of a year.
How is compound interest determined?To calculate compound interest, multiply the original loan principle by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the loan's principal plus compound interest.Compound interest is one of the most useful financial concepts, which states that the interest you earn each year is added to your principal so that the balance not only grows, but grows at an increasing rate. It serves as the foundation for everything, including a person's personal savings strategy and the long-term growth of the stock market.Therefore,
20000(.071)t ≤ 500(12)
1420t ≤ 6000
t = 4.2
Hence, Her loan is 4.2 years long to the nearest tenth of a year.

Find the area of the shape below
No links, docs, files, drives etc
I will mark the correct answer brainlyest
You earn many points
Answer: 2200
Step-by-step explanation:
First we will find the area of the triangle, the formula for that is bh/2
(base multiplied by height divided by 2) then we input the numbers into our formula, 30 is the height of the triangle and 40 is the length of the base. So we have to solve 40*30/2 which is 600, then we solve for the square on the bottom which is b*h ( base multiplied by height) so it is 40*40, so we would get 1600, then we add 600 and 1600 together and get 2200.

Find the circumference of the circle. Use 22/7 for pi.
Answer:
44
Step-by-step explanation:
circumference = 2πr = 2*(22/7)*(14/2) = 44
Answer:
C = 44 cm
Step-by-step explanation:
The diameter is 14.
The formula for circumference is
C = pi * d where d is the diameter
C = 22/7 * 14
C = 22 * 2
C = 44 cm

express the sum of 2x and y is multiplied by 5 in an algebraic expressions
Answer:
(2x + y)*5
Step-by-step explanation:
Translating the word problem into an algebraic expression, we have;
(2x + y) * 5
Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.
Simplifying further by opening the bracket, we have;
(2x + y)*5 = 10x + 5y
