Answer:

B. 2s + 100 when s=80 the latest balance of Ahmed’s savings is $260

Step-by-step explanation:

We are given that the savings = $s and current amount  $c.

Now, Ahmed has doubled his savings. This means that the new savings = $2s

Also, he had deposited $100.

So, the current amount of Ahmed is given by c = 2s + 100.

Moreover, if the savings is $80 i.e. s = 80, the current amount is,

c = 2 × 80 + 100

i.e. c = 160 + 100

i.e. c = 260

So, the current amount if savings is $80 is $260.

Hence, the expression for current amount is 2s + 100 and if s = 80, the current amount is $260.

The mean is 8 and the lower quartile is 6.

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.

The volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

The volume of the cuboid is the space occupied by the 3D object cuboid. It is the product of the length, width, and depth of the cuboid.

As it is given that we need to make a rectangular foundation, therefore, the shape of the foundation will be a cuboid with sides 5 feet wide, 17 feet long, and depth of 6 inches.

Now, as we know large amounts of concrete can be purchased by the cubic yard only, therefore, we will convert each of the sides of the rectangular foundation into yards.

[tex]\rm Wide, w = 5\ feet = 5 \times \dfrac{1}{3} = \dfrac{5}{3}\ yards\\\\Length, L = 17 feet = 17 \times \dfrac{1}{3} = \dfrac{17}{3}\ yards\\\\Depth, D = 6\ inches = 0.5\ feet = 0.5 \times \dfrac{1}{3} = \dfrac{0.5}{3}\ yards\\\\[/tex]

Now, we know that the volume of the cuboid is given as the product of its length, width, and depth. therefore,

[tex]\text{Volume of Cuboid} = Length\times Width\times Depth[/tex]

                             [tex]= \dfrac{5}{3} \times \dfrac{17}{3} \times \dfrac{0.5}{3}\\\\= \dfrac{42.5}{27}\\\\=1.574\rm\ yards^3[/tex]

Hence, the volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

Substitute  [tex]\$10,000[/tex] for [tex]y[/tex]

[tex]\Rightarrow 10,000=24,000\left(0.845\right)^t\\\\\Rightarrow \left(0.845\right)^t=\dfrac{5}{12}\\\\\Rightarrow \left(0.845\right)^t=0.41666\\\text{Taking log both sides}\\\Rightarrow t\ln (0.845)=\ln (0.4166)\\\\\Rightarrow t=\dfrac{\ln 0.4167}{\ln 0.845}\\\\\Rightarrow t=5.197\approx 5.2\ \text{years}[/tex]

(b) After 50 years, it is

[tex]\Rightarrow y=24,000\left(0.845\rght)^{50}[/tex]

Answer:

42.42 yards

Step-by-step explanation:

Given :-

And we need to find the length of other leg. So since it is a right angled triangle we can use the Pythagoras Theorem which is ,

Pythagoras Theorem :-

Using Pythagoras Theorem :-

[tex]:\implies[/tex] p² + b² = h²

[tex]:\implies[/tex] 15² + p² = 45²

[tex]:\implies[/tex] 225 + p² = 2025

[tex]:\implies[/tex] p²= 1800

[tex]:\implies[/tex] p = 42.42

Hence the measure of other leg is 42.42 yards.

Answer:

To divide by (x+1) in synthetic division, you divide by -1.

-1    1   -7   4   12

         -1    8   -12

—————————-

     1   -8   12   0

This gives us x^2 -8x +12x  which factors to (x-2) (x-6).  We still have the factor of (x+1)  so the zeros will be 2, 6, and -1.

Answer:

2 AND -10

Step-by-step explanation:

Answer:

domain: all real numbers except 2 and -10; x-intercept: 4; y-intercept:  1/5

Step-by-step explanation:

The domain consists of the set of all possible values x can be. In a fraction, the denominator cannot be equal to 0. We can solve for the values x cannot be equal to by factoring and exclude them out of the domain once we’ve found them:

To factor x^2 + 8x - 20, we are looking for two numbers that have a product of -20 and a sum of 8. These two numbers are 10 and -2. So, it can be factored to:

(x + 10)(x -2) not equal 0

So x ≠ 2 and x ≠ -10.

To find the x-intercept, the value of y would be zero. We can substitute y as 0 to get:

0 = (x - 4) / x^2 + 8x - 20

The only way for this fraction to equal 0, is for the numerator to be 0. We get the equation:

x - 4 = 0,

And x = 4

To find the y-intercept, the value of x would be 0. We can substitute x with 0 to get:

y = -4 / -20 = 1/5

These answers align with the second option.
