Answer:
(0, 5000)
The value of the account at the start of the year is 5000
Step-by-step explanation:
Given the equation that represents the value, y, of one account that was left inactive for a period of x years as;
y = 5000(0.98)^x
The y-intercept of the equation occurs at x = 0
Substitute x = 0 into the expression
y = 5000(0.98)^0
y = 5000(1) (any value raise to power of zero is 1)
y = 5000
Hence the y intercept is (0, 5000)
This means that the value of the account at the start of the year is 5000
A rectangle’s length is 9 more than 4 times its width. The area of the rectangle is 90 square inches. What is the width of the rectangle?
Answer:
15/4 in or 3.75 in
Step-by-step explanation:
Find your equations:
L = 4w + 9 in
A = L*w = 90 in^2
Substitute L:
L*w = 90 in^2 <-- L = 4w + 9
(4w + 9in)w = 90 in^2
4w^2 in^2 + 9w in = 90in^2
Solve Simultaneously:
w = -6 in, 15/4 in
Width is positive so it is 15/4 in or 3.75 in.
Double check:
(4w + 9in)w = 90 in^2
(4*3.75in + 9in)(3.75in) = 90 in^2

The diagonal of a cube is 20 cm. Identify the length of an edge. Round to the nearest tenth, if necessary.
answers:
20 cm
14.1 cm
13.8 cm
11.5 cm
The length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a cube.
The diagonal of a cube is 20 cm.
Let a be the side length of the cube.
As we know, from the Pythagoras theorem we can calculate the length of the face diagonal.
Pythagoras' theorem can be defined as the square of the hypotenuse in a right-angled triangle equal to the sum of the squares of the other two sides.
Length of a face diagonal = √2a
Length of body diagonal = √3a
√3a = 20 (given)
a = 20/√3
a = 20/1.732
a = 11.5 cm
Thus, the length of an edge or side length of the cube is 11.5 cm if the diagonal of a cube is 20 cm option (d) is correct.

Answer:
13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)
= 3x + 4y - 3z - 2x + 6y - 7z
= 3x - 2x + 4y + 6y - 3x - 7z
= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1

So say someone did 1000 push ups a day for 8 years 2920 days in 8 years and you want to do the same amount but in 2 months how many would you have to do a day
Answer:
48,667 if you round it..
Step-by-step explanation:
1000x2920 = 2,920,000
divided by 2 months
2,920,000/2 = 1,460,000
and theres 30-31 days in a month
1,460,000/30 = 48,666.67

In her metalwork class, Anja cut a square of
tin, of edge 3.7 cm, from a larger square of
edge 6.3 cm. What area of tin was left?
Given:
Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.
To find:
The area of the remaining tin.
Solution:
Area of a square is:
[tex]Area=a^2[/tex]
Where, a is the edge of the square.
Area of the smaller square is:
[tex]A_1=(3.7)^2[/tex]
[tex]A_1=13.69[/tex]
Area of the larger square is:
[tex]A_2=(6.3)^2[/tex]
[tex]A_2=39.69[/tex]
The area of the remaining tin is:
[tex]A=A_2-A_1[/tex]
[tex]A=39.69-13.69[/tex]
[tex]A=26[/tex]
Therefore, the area of the remaining tin is 26 sq. cm.

The figure shows a kite inside a rectangle. Which expression represents the area of the shaded region?
A. 2x^2
B. 4x^2
C. 6x^2
D. 8x^2
Thanks!!
[tex] \huge \mathrm{Answer࿐ }[/tex]
Fig - 1 : Rectangle
length = 3x + x = 4x width = x + x = 2x[tex] \boxed{\mathrm{Area = length \times width}}[/tex]
[tex]4x \times 2x[/tex][tex]8 {x}^{2} [/tex]_____________________________
Fig - 2 : Kite
[tex] \boxed{\mathrm {Area = \dfrac{1}{2} \times d_1 \times d_2 }}[/tex]
[tex] \dfrac{1}{2} \times 4x \times 2x[/tex][tex]4 {x}^{2} [/tex]_____________________________
Area of shaded region :
Area of rectangle - Area of kite [tex]8 {x}^{2} - 4 {x}^{2} [/tex][tex]4 {x}^{2} [/tex]So, Correct option is B. 4x²

Nadia needs 2/5 cup of orange juice for a punch recipe. She will double the recipe to make punch for a party. Which statement is true?
Answer:
Step-by-step explanation:
There's not a lot to go on with the details provided in the question, but based on all you said, if there isn't more to the question, then the true statement is the fact that Nadia needs 2/5 cup of orange juice for punch recipe.
Twice that amount is 4/5, and logically, that can't suffice in a party, except it's a party of 3, maybe 5 people. I'm assuming the people in the party would be much more than that. Makes the fraction impossible

Answer:
8) 50°, 50°, 130°, 130°10) 120°Step-by-step explanation:
Ex 8Adjacent interior angles of a parallelogram are supplementary
Let the small angle is x, the other angle is:
2x + 30°The sum of two angles is 180°
x + 2x + 30° = 180°3x = 150°x = 50°The angles are 50°, 50°, 130°, 130°
Ex 10Sum of interior angles of a pentagon is:
S = 180°(5 - 2) = 540°Two of the angles are supplementary, so they sum to 180°
The sum of the remaining 3 angles is:
3x = 540° - 180°3x = 360°x = 120°Each of the congruent angles is 120°

What is the probability of rolling a 1 ora 4 on a number cube labeled 1 through 6?
Answer:
For each number, there is a 1/6 probability of rolling it (so 1/6 for the 1 and also 1/6 for the 4).
This means that the probability of rolling either a 1 or a 4 on a given roll is
1 /6 + 1 /6 = 2/6 = 1/3
hope this answer helps you.....
Answer:
Is 1/6
