You estimate that it will take five years to complete your college education. Your parents want to invest enough money today at 12 per cent to enable you to withdraw $5000 at the end of each year for the next five years with nothing left at the end of the five-year period. How much money do they need today?
Answer:
the present value is $18,025
Step-by-step explanation:
The computation of the amount that should be needed today is given below:
Given that
NPER = 5
RATE = 12%
PMT = $5,000
FV = $0
The formula is shown below:
=-PV(RATE,NPER,PMT,FV)
AFter applying the above formula, the present value is $18,025

3x + 2y = -7
2x - 5y = 8
please help solve!! i need my work need to me shown so please help me! ❤️
Answer:
56/19
Step-by-step explanation:
I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...
2X + 5(1.5X) = 8
2X + 7.5X = 8
9.5X = 8
19X = 16
X = 16/19
While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...
3X = 2Y
3(16/19) = 2Y
48/19 = 2Y
24/19 = Y
With the value of X and the value of Y, we can answer the question that's asked:
2X + Y = ?
2(16/19) + 24/19 =
32/19 + 24/19 =
56/19
Final Answer: 56/19
Answer:
[tex]x = - 1[/tex]
[tex]y = - 2[/tex]
Step-by-step explanation:
[tex]3x + 2y = - 7[/tex]
[tex]2x - 5y = 8[/tex]
Apply elimination method. Let multiply the bottom equation by -3/2.
[tex]2 \times - \frac{3}{2} x = - 3[/tex]
[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]
[tex]8 \times - \frac{3}{2} = - 12[/tex]
Substitute new equation and add it to the top equation
[tex]3x + 2y = - 7[/tex]
[tex] - 3x + 7.5y = - 12[/tex]
[tex]9.5y = - 19[/tex]
[tex]y = - 2[/tex]
Now plug -2 for y into any equation and solve for x.
[tex]3x + 2( - 2) = - 7[/tex]
[tex]3x - 4 = - 7[/tex]
[tex]3x = - 3[/tex]
[tex]x = - 1[/tex]

How long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole? I need this fast
Answer:
Step-by-step explanation:
either 1 foot or 33 ;-;
The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.
Let the value is C.
The Pythagoras' theorem,
C² = (11)² + (12)²
C² = 121 + 144
C² = 265
C = 5.1 feet.
Therefore, the value is 5.1 feet.

∠A and ∠B are vertical angles. If m∠A=(5x+5)∘and m∠B=(4x+29)∘, then find the measure of ∠A.
Answer:
∠A = 175∘
Step-by-step explanation:
∠A = ∠B
5x-5= 4x+29
x = 34
∠A= 34*5+5
∠A=170+5=175
5x+5= 4x + 29

5x=4x+24
-4x -4x
x=24
m∠A=5x+5

Supppose a rectangle will undergo a rotation about the origin of a coordinate plane and a translation of 6 units down. Which of these is a true statement
Options:
The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.
The resulting rectangle will be congruent to the original rectangle only if the rotation occurs before the translation.
The resulting rectangle will be congruent to the original rectangle only if the translation occurs before the rotation.
The resulting rectangle will not be congruent to the original rectangle regardless of the order of the rotation and the translation.
Answer:
The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.
Step-by-step explanation:
See attachment for options
Given
Shape: Rectangle
Transformation
- Rotation
- Translation 6 units down
Required
True statement about the transformation
From the options, we understand that we are to answer the question based on whether or not the image of the transformation will equal the original.
The given transformations are rigid transformations and as such, they do not in any way change the measure of the length and/or angle of the new image, after transformation
So, irrespective of which transformation comes first, both shapes will be congruent.
Hence: (a) is true

The vertices of quadrilateral WXYZ are W(-1,4); X(3,5); Y(4,1); Z(00). What kind of quadrilateral is it? Explain how you know this. Be as specific as possible.
Answer:
This quadrilateral is a SQUARE.
When we plot these points, we realize that they are equal distance apart.
So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

what is the length of line BC in the right triangle below?
Answer:
D. 39
Step-by-step explanation:
BC^2 = BA^2 + AC^2
BC^2 = 15^2 + 36^2
BC = square root (1521)
BC = 39
Answer:
D) 39
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean thm formula
Formula: a² + b² = c²
15² + 36² = c²
225 + 1296 = c²
1521 = c²
[tex]\sqrt{1521} =\sqrt{c^2}[/tex]
c = 39

I Need help ASAP please and Thankyou!!
Answer:
Step-by-step explanation:
m∠R = 180° - 110° [Linear pair of angles are supplementary]
m∠R = 70°
m∠S = 45° [Vertically opposite angles]
By triangle sum theorem,
m∠P + m∠R + m∠S = 180°
m∠P + 70° + 45° = 180°
m∠P = 180 -115
= 65°
Therefore, m∠A = m∠P = 65° [Vertically opposite angles]
By triangle sum theorem,
m∠B + m∠S + m∠T = 180°
m∠B + 45° + 65° = 180°
[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]
m∠B = 180° - 110° = 70°
m∠C + m∠B = 180° [Linear pair of angles are supplementary]
m∠C = 180° - 70° = 110°
m∠D + m∠T = 180° [Linear pair of angles are supplementary]
m∠D + 65° = 180°
m∠D = 115°

What number is 25% of 5/8?
(( Can someone please give the formula, this is like reading a foreign language to me lol ))
Thank you.
A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.
Now multiply the two.
0.25x5/8.
We need to convert 5/8 to a decimal, which is 0.625.
0.25x0.625=0.15625.
Now convert the decimal to a fraction, which is 5/32.

Step-by-step explanation:
The given expression is
[tex]p=-0.4t^2+130t+1200[/tex]
where
[tex]p[/tex] = Population of rabbits
[tex]t[/tex] = Time in months
Now, the population is greater than [tex]9500[/tex]
