Answer:

x = 1    y = 3    z = 1

Step-by-step explanation:

(1)  x - 3y - z = -9           (2)   -2x + y + 2z = 3        (3)   2x + y + 3z = 8

                                2x(1)     2x - 6y - 2z = -18      (2)  -2x + y + 2z = 3

                                                 - 5y = -15                           2y + 5z = 11

                                                      y = 3                            2(3) + 5z = 11

                                                                                            6 + 5z = 11

                                                                                                  5z = 5

                                                                                                    z = 1

       x - 3(3) - 1 = -9

       x - 9 - 1 = -9

            x - 10 = -9

            x = 1

Answer:

4, 860 yards

Step-by-step explanation:

To find area multiply l*w. So, multiply 90 by 54 to get your answer:

90 yards × 54 yards = 4, 860 yards

if rectangular field is 90 yards long and 54 yards wide then the area of the field is 4860 square yards.

The area of Rectangle is length times of width.

Given that Grass seed is going to be spread over a playing field.

The number of bags of seed needed depends on the size of the field.

The rectangular field is 90 yards long and 54 yards wide.

We need to find the area of the field.

Length of field = 90 yards

Width of field = 54 yards

Area of Field = Length×Width

=90×54

=4860 square yards.

Hence, if rectangular field is 90 yards long and 54 yards wide then the area of the field is 4860 square yards.

Answer:

A. 55°

Step-by-step explanation:

Complementary angles are angles that add up to give us 90°.

Since <A and <B are complementary angles, it implies that:

m<A + m<B = 90°

If m<A = 35°, therefore:

35° + m<B = 90°

Subtract 35° from each side

m<B = 90° - 35°

m<B = 55°

Answer:

5x4x2

Step-by-step explanation:

The total area of the figure id 35 square cm.

The amount of space taken up by a two dimensional space is called area.

The formula for the area of a triangle is

[tex]A = \frac{1}{2} (b)(h)[/tex]

Where,

A is the area of triangle.

b is the base of a triangle.

h is the height of the triangle.

The formula for the area of square is

[tex]Area = a^{2}[/tex]

Where,

a is the side length of square.

According to the given question.

A triangle is resting on a square.

Side length of square, a = 5cm

So, the area of square = [tex]5^{2} = 25 square cm[/tex]

Also, a triangle with height 4cm.

Since, the triangle is resting on a square.

⇒ Base length of the triangle = 5cm

So, the area of triangle = [tex]\frac{1}{2} (5)(4)= 10 square cm[/tex]

Therefore,

The total area of the given figure  = Area of square + Area of triangle

⇒ Total area of figure = (25 + 10) square cm

⇒ Total area of figure = 35 square cm

Hence, the total area of the figure id 35 square cm.

Answer:

The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for population growth, after x years, is given by:

[tex]P(x) = P(0)(1+r)^x[/tex]

In which P(0) is the initial population and r is the growth rate.

A model predicts that the population of a certain town was 10,000 in 2001.

This means that [tex]P(0) = 10000[/tex]

8% yearly increase.

This means that [tex]r = 0.08[/tex]. So

[tex]P(x) = P(0)(1+r)^x[/tex]

[tex]P(x) = 10000(1+0.08)^x[/tex]

[tex]P(x) = 10000(1.08)^x[/tex]

The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]

Answer:

[tex]y = 10x[/tex]

Step-by-step explanation:

Given

The attached plot

Required

The line of the best fit using [tex](8,80)[/tex] and [tex](2,20)[/tex]

We have:

[tex](x_1,y_1) = (8,80)[/tex]

[tex](x_2,y_2) = (2,20)[/tex]

Calculate slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{20 - 80}{2- 8}[/tex]

[tex]m = \frac{-60}{-6}[/tex]

[tex]m = 10[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 10(x - 8) + 80[/tex]

Expand

[tex]y = 10x - 80 + 80[/tex]

[tex]y = 10x[/tex]

Answer: Choice B is correct.

==================================================

Explanation:

We are told that the derivative function f ' (x) is positive for all real numbers x. This means that f(x) is increasing for all real numbers. An increasing function goes uphill as you move from left to right. This rules out choices C and D.

We're also told that the integral of f(t), from t = 4 to t = 7, is equal to 0. Because f(x) is increasing, this must mean that some portion of f(x) is below the x axis and some portion is above the x axis when focused on the interval of [tex]4 \le x \le 7[/tex]. This allows us to rule out choice E since there are no portions that are below the x axis here.

At this point, the answer is between A and B. We can rule out choice A for similar reasoning we did with choice E. This time, there is no portion that is above the x axis. We need a negative area (below the x axis) to counterbalance with a positive area (above the x axis) so that the two areas cancel out and add to 0. That doesn't happen with choice A.

The only thing left is choice B so that must be the answer. We have a portion below the x axis and a portion above it, so it's possible that these two areas cancel out to add to 0. Since we don't know the actual f(x) function, it's impossible to tell whether that happens or not.

Answer:

3603600

Step-by-step explanation:

I used my calculator

Answer:

Step-by-step explanation:

The total cost for the laptop for 3 years is $1174.20.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Cost of the laptop when purchased = $780

Daily cost = $0.36

Number of days in 3 years = 3 × 365 = 1095 days

Cost for the laptop for 3 years = 1095 × $0.36

                                                   = $394.20

Total 3 year cost = $394.20 + $780

                            = $1174.20

Hence the total cost for the laptop is $1174.20.
