Answer:

1. 109

2. 29

3. 71

Step-by-step explanation:

1. since a triangle's interior angles always add up to 180, you can add 35 and 36 to get 71, then subtract that from 180 to find the third angle

2. the unnamed angle in triangle RUV is supplementary to <1.Supplementary angles are angle the add up to 180. So you can subtract 109 from 180 to find the unnamed angle. It is 71. Now you can repeat the steps in question one to find <2 in triangle RUV. You get that <2 is 29

3. Angle 3 and the unnamed angle are vertical angles. This means that they are opposite to each other and are congruent. This means that they have the same measure. Knowing that the unnamed angle is 71, we can say that angle 3 is also 71.

Answer:

The sum of the first 100 odd numbers is 10,000

Step-by-step explanation:

Here, we want to find the sum of the first 100 odd numbers

Mathematically, we can use the formula for the sum of term in a sequence which is;

Sn = n/2(a + L)

where n is the number of terms

L is he last term

a is the first term

The difference between two consecutive odd numbers is 2

So:

T100 = 1 + (100-1)2

T100 = 1 + 198

T100 = 199

So;

sn = 100/2(1 + 199)

Sn = 50(200)

Sn = 10,000

Step-by-step explanation:

the sum of the first 100 odd numbers 10000

The domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].

Hence, the restrictions would be:

and

Step-by-step explanation:

Given

The domain of u(x) is the set of all real values except 0.

so

domain = (-∞, 0) U (0, ∞)

The domain of v(x) is the set of all real values except 2.

so

domain = (-∞, 2) U (2, ∞)

For the function composed function (u circle v) (x), we need to apply first the function [tex]v(x)[/tex]  whose argument is (x), and then the function [tex]u (v(x) )[/tex] whose argument is [tex]v(x)[/tex].

Please note that the domain of the composed function (u circle v) (x) must have to take into account the values for which both functions u(x) and v(x) are defined.

Therefore, the domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].

Hence, the restrictions would be:

Step-by-step explanation:

The  range & domain {0, 12, 24, 36, 48, 60, 72}.

To discover the area and variety, we without doubt solve the equation y = f(x) to decide the values of the unbiased variable x and achieve the area. To calculate the variety of the feature, we actually express x as x=g(y) after which find the domain of g(y).

Range, the distinction between the very best and the bottom values in a set. c programming language (mathematics), additionally referred to as range, is a set of real numbers that consists of all numbers between any two numbers inside the set.

The input values. given that there may be an even root, exclude any actual numbers that result in a terrible wide variety inside the radicand. Set the radicand greater than or equal to zero and remedy for x. the solution(s) is the area of the feature.

Step-by-step explanation:

Answer:

Calculator 1: Calculate the percentage of a number.

For example: 85% of 350 = 297.5

Calculator 2: Calculate a percentage based on 2 numbers.

For example: 297.5/350 = 85%

Answer:

$297.50

Step-by-step explanation:

turn 85% into a decimal: .85

and then multiply with $350

350*.85= 297.50

Answer:

x = - 6, x = 1

Step-by-step explanation:

To find the zeros, let f(x) = 0, that is

(x - 1)(x + 6) = 0

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 1 = 0 ⇒ x = 1

Answer: B) 1 1/2 cups of flour: 1 cup of sugar

Step-by-step explanation:

When you look carefully at the graphed line, it intersects the grid at 1 1/2 on the vertical scale for Flour and at the same point, it intersects the 1 on the horizontal scale for Sugar. That is answer B.

Answer A is a close miss! When you follow the grid line across from 2 on the vertical scale, you see that the graphed line crosses it at just a little less than 1 1/2.

Answer:

Equation:   y = 65x

Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.

Step-by-step explanation:

Pick any two points to find slope, let's got with (3, 195) and (4, 260):

  slope m = (y₂- y₁) / (x₂ - x₁)

                = (260 - 195) / (4 - 3)

                = 65 / 1

            m = 65

Find y-intercept by using m from above and another point from your table, let's go with (5, 325):

  y = mx + b

  325 = 65(5) + b

  325 = 325 + b

  b = 0

Use m and b to form equation of line:

  y = mx + b

  y = 65x + 0

  y = 65x

Check:

  point (3, 195):   195 = 65(3)       ====>   195 = 195

  point (4, 260):   260 = 65(4)     ====>   260 = 260

  point (5, 325):   325 = 65(5)     ====>   325 = 325

  point (6, 390):   390 = 65(6)     ====>   390 = 390

Example of a point that doesn't belong on table:

  point (8, 500):    500 = 65(8)    ====>   500 ≠ 520

The equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The table shows a representation of the number of miles a car drives over time. Hours, x

The equation of the line:

y - 195 = (260-195)/(4-3)[x - 3]

y - 195 = 65(x - 3)

y = 65x - 195 + 195

y = 65x

Plug x = 8

y = 195(8) = 1560

Thus, the equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.
