Answer:

area of parallelogram= 59.39 cm square

3. 5

Constant terms are terms with no variables attached to them, and will not change under any circumstances. A variable is typically denoted by a Latin Alphabet.

4. 4

The coefficient is the whole number found in front of the variable, typically being multiplied to it. In this case, you are solving for the coefficient that is found in front of g², which is 4.

5. -3c

The coefficient -3 is found at the 3rd term of the expression.

6. -12x & -17x ; 15y & 16y

Like terms are terms with the same variable as well as the same amount of variables. For example x² is not a like term of x, though both variables have x to signify them.

7. 3c

Unlike terms are terms that do not share at least one partner of the same amount of variables. c is a variable by itself with no other terms containing it, and so is your answer.

Answer: Choice B)  [tex]y \ge \frac{3}{4}x-3[/tex]

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)

This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.

The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.

So overall, the inequality sign is "greater than or equal to". That leads to choice B.

Answer: No you cannot.

Step-by-step explanation:

They are different units and cannot be combined.

Answer:

x = 4

Step-by-step explanation:

Given the points (4, - 1) and (4, 8)

Note the x- coordinates are 4 in both cases.

This indicates the line passing through the points is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through. In this case 4, thus

x = 4 ← equation of vertical line

Step-by-step explanation:

Any of the vertical lines is perpendicular to any of the horizontal lines.

The open/close/adjust handle is perpendicular to the blind slats and the blind frame.

The threads that hold the slats, and the string that raises/lowers them are also perpendicular to the slats.

70 = 100 - 2•15 is 2 s.d.'s below the mean.

130 = 100 + 2•15 is 2 s.d.'s above the mean.

By the empirical rule,

Pr [70 ≤ X ≤ 130] = Pr [-2 ≤ Z ≤ 2] ≈ 95%

(where Z is normally distributed with mean 0 and s.d. 1)

Answer:

-18

Step-by-step explanation:

If you turn 2 1/4 into an improper fraction, you get 9/4

Turn -8 into an improper fraction, you get -8/1

Equation: 9/4*-8/1

You can cross cancel the 4 and the 8 so your equation becomes 9/1*-2/1 which becomes 9*-2

Multiply and you get -18 :)

Answer:

25 pi square yd OR rounded pi to 3.14: 78.5 square yd

Step-by-step explanation:

Use the formula volume of cylinder = base area × h to determine the value of the base area.

Diameter: 5 yd

Height: 4 yd

(5/2)^2 Pi x 4 = 25 pi square yd.

Answer:

78.5 yd

Step-by-step explanation:

= [tex]\pi[/tex]r²h

= (3.14)(2.5)²(4)

= (3.14)(6.25)(4)

= 19.625 x 4

= 78.5 yd

As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ

In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.

Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.

Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.

The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.

Here we need to find the expression.

Bloodstream = 500 milligrams

So, the expression for this proportional relationship is written as;

P(t) = 500 + e⁻⁰²ˣ
