Answer:

~10525.41 after 7 years

Step-by-step explanation:

y=a(1+r)^x

That's the equation for exponential growth

a= the starting amount

r= the rate at which it is growing

x=years

with that information

a=7000

r=6% or 0.06

so y=7000(1+0.06)^x -> y=7000(1.06)^x

x=7

y=7000(1.06)^7

y~10525.41

Step-by-step explanation:

x² + 2x

x(x + 2)

OR

x² + 2x = 0

x(x + 2) = 0

x = 0 or x + 2 = 0

x = 0 or x = - 2

Answer:

Perimeter of sector is 47.93 cm which is greater than 47.5 cm

Step-by-step explanation:

Mathematically, the perimeter of a sector is length of the arc plus 2 radii

The length of the arc is;

theta/360 * 2 * pi * r

where theta is the angle subtended by the arc at the center of the circle

Thus, we have

135/360 * 2 * 22/7 * 11 = 25.93

Add 2 radii = 25.93 + 2(11) = 47.93 cm

This is greater than what we are asked to calculate and thus we have shown what we are asked to show

Answer:

47.9cm>47.5cm

Step-by-step explanation:

135(angle) /360 x 2 pi r (to give arc of the sector)

135/360 x 2 x 3.142 x 11 = 25.92cm

add 11 + 11 (radius)

25.92 + 22= 47.9cm

122÷2=61

Answer:

Step-by-step explanation:

all we have to do is plug in 2 for x into the equation:

-8(2) + 5 -2(2) -4 + 5(2)

-16 + 5 -4 -4 + 10

-11 -8 + 10

-19 + 10

the answer is

-9

to simplify the equation we’ll combine like terms

-8x + 5 -2x -4 + 5x

-10x + 1 + 5x

-5x + 1

now we’ll plug in 2 for x

-5(2) + 1

-10 + 1

the answer is still

-9

Answer:

x=7,x=-4

Step-by-step explanation:

[tex]2x-3=11\\2x=11+3\\2x=14\\x=7\\\\2x-3=-11\\2x=-11+3\\2x=-8\\x=-4[/tex]

Answer: x=7, x= -4

Step-by-step explanation: Ok because of the absolute value signs, there are going to be two different equations. The first one is just 2x-3=11. Solve that: 2x=14, x=7. Then because the answer in the absolute value could also be -11 (because absolute values always have to be positive), there is another equation : 2x-3=-11. Add 3 on both sides, 2x=-8, x=-4

no

Answer:

f(x) = 2x^2 + 12x +10

Step by step solution:

x = 1 x = 5 y = 10

f(x) = a(x+1)(x+5)

f(0) = a(1)(5) = 10

5a = 10

Divide by 5

a = 2

f(x)= 2(x+1)(x+5)

f(x) = 2(x^2 +6x +5)

f(x) = 2x^2 + 12x +10

Answer:

Step-by-step explanation:

Part A:

Yes, the numbers of white and yellow flowers in Cara's arrangements are proportional.

yellow flowers = y

white flowers = w

5y = 3w

Therefore, the numbers of white and yellow flowers in Cara's arrangements are proportional.

Part B:

yellow flowers = y

white flowers = w

6y = 4w

Therefore, the numbers of white and yellow flowers in Hector's arrangements are proportional.

Isosceles triangle

Step-by-step explanation:

Answer: This triangle is a Right Isosceles triangle so you would select B. & D.

Explanation: This triangle isn't equilateral sense the three sides / three angles aren't equal. And isn't scalene sense scalene triangle have no equal sides and no equal angles.

Hi there!

[tex]\large\boxed{x \leq -9}[/tex]

3x - 7 ≥ 4x + 2

Subtract 3x from both sides:

3x - 3x - 7 ≥ 4x - 3x + 2

-7 ≥ x + 2

Subtract 2 from both sides:

-7 - 2 ≥ x + 2 - 2

-9 ≥ x

x ≤ -9

Answer:

B. Yes, 3.5

Step-by-step explanation:

Proportional Variables

Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:

y = k.x

Or, equivalently:

k = y/x

k is called the constant of proportionality.

The table gives three points: (13,45.5) (14,49) (15,52.5)

To find out if the values correspond to a proportional relationship, we find the value of k for each pair:

k = 45.5 / 13 = 3.5

k = 49 / 14 = 3.5

k = 52.5 / 15 = 3.5

Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5

Answer: I believe it would be 8.

Answer:

Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while

Correlation Coefficient r value of 0.80 means a strong positive relationship

Step-by-step explanation:

Correlation Coefficient (r) signifies the strength of relationship which exists between two linear variables. The value of r ranges from - 1 to + 1 where positive and negative values signifies a positive and negative relationship relationship respectively.

The closer the r value is to either +1 or - 1, the greater the strength of the relationship while a r value of 0 means, there is no relationship between the two variables.

Hence in the scenario above :

Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while

Correlation Coefficient r value of 0.80 means a strong positive relationship

Answer:

Step-by-step explanation:

Correlation Coefficient r value of 0.05 means a weak or very weak positive relationship while

Correlation Coefficient r value of 0.80 means a strong positive relationship

Answer:

No real solutions

Step-by-step explanation:

Distribute the -3

-3x - 9 = -3x -3 -5

-3x - 9 = -3x - 8

add 3x to both sides

-9 = -8

Answer:

Todd's

Step-by-step explanation:

Given the expression x^2+6x+5=8, we are to determine which whether Imani or Todd method will work

Imani method might not work because he hasn't written the equation in standard form before factorizing. He should have equated the expression to zero first before factorizing and finding the zeros of the expression. The equation should have been written in the form ax²+bx+c = 0 first.

For Todd, his method will work because he used the completing the square method. The value at the right hand may not necessarily be zero before applying the rule. The idea is to make the quadratic equation complete and a perfect square.

This is achieved by adding the half of coefficient of x to both sides of the expression before simplifying.

From the expression x²+6x+5 = 8 we can see that adding 4 to both sides will make the quadratic equation on the left a perfect square.

x²+6x+5= 8

x²+6x+5+4= 8 +4

x²+6x+9 = 12

x²+3x+3x+9 = 12

x(x+3)+3(x+3) = 12

(x+3)(x+3) = 12

(x+3)² = 12

We can see that the expression at the left hand is now a perfect square. Hence Todd solution strategy will work
