Help ASAP.. Find the measure of each missing angle .. M<1? M<2? M<3? M<4? M<5?

Answers

Answer:

m<1=62°

m<2=23°

m<3=157°

m<4=23°

m<5=62°

Step-by-step explanation:

m<1= 180-118=62

m<2=180-95-62=23

m<3=180-23=157

m<4=m<2=23

m<5=m<1=62

Measures of the missing angles

m∠1 = 62° , m∠2 = 23°, m∠3 = 157° , m∠4 = 23° , m∠5= 62°

What is an angle?

An angle is the figure formed by two rays called sides of the angle sharing a common endpoint called the vertex of the angle.

Given,

In the figure

sum of angles on a straight line is 180° .

m∠1 + 118° = 180°

m∠1 = 180° - 118°

m∠1 = 62°

In a triangle, measurement of all interior angles is 180°

m∠1 + m∠2 + 95° = 180°

62° + m∠2 + 95° = 180°

m∠2 + 157° = 180°

m∠2 = 180° - 157°

m∠2 = 23°

Sum of angles on a straight line is 180°

m∠2 + m∠3 = 180°

23° + m∠3 = 180

m∠3 = 180° - 23°

m∠3 = 157°

Since ∠2 and ∠4 are supplementary angles

m∠4 = m∠2

m∠4 = 23°

Sum of all interior angles of a quadrilateral is 360°

m∠3 + m∠4 + m∠5 + 118° = 360°

157 + 23 + m∠5 +118 = 360

m∠5 + 298 = 360

m∠5 = 360 - 298

m∠5 = 62°

Hence, m∠1 = 62°, m∠2 = 23°, m∠3 = 157°, m∠4 = 23°, m∠5= 62° are the measures of the missing angles.

Answer:

5 and 5b: y=-2x+10

5a: y-2=-2(x-6)

Step-by-step explanation:

We can use the mentioned data points to identify the slope. Time will always the x coordinate/axis, so gallons will be the y coordinate/axis. As you probably already know, slope is rise over run, so we can measure the change in y over the change in x, or we can do [tex]\frac{y-y_{1}}{x-x{1}}[/tex]. When we plug in our points, (2,6) and (5,0), we get  [tex]\frac{6-0}{2-5}[/tex], or [tex]\frac{6}{-3}[/tex], or [tex]\frac{2}{-1}[/tex], or simply -2. So our slope is -2.

We can use our y-intercept (which is (0,10), as mentioned in the attached graph and table) to make the equation, in slope-intercept form, [tex]y=-2x+10[/tex] This can answer both question 5 and 5b. Remember that slope-intercept form is written using the format y=mx+b, where x any given x-coordinate, y is the corresponding y-coordinate, m is the slope and b is the y-intercept.

To put this equation in point-slope form, one must first remember that point-slope form is written in the format [tex]y-y_{1} = m(x-x_{1})[/tex], using the coordinates of any given coordinates on the same line, except for the y intercept. m also represents slope in this equation. So for this one, we can easily use (2,6). we can plug in these coordinates to get the equation y-2=-2(x-6).

Hope this helps.

Answers

Answer:

x = {0, π/3, π, 4π/3}

Step-by-step explanation:

4cos⁴(x) - 5cos²(x) + 1 = 0

(u² - 1)(4u² - 1) = 0

u² - 1 = 0

u² = 1

u = ± 1

cos x = ± 1

=> x = 0 or π

4u² - 1 = 0

4u² = 1

u² = 1/4

u = ± 1/2

cos x = ± 1/2

=> x = π/3 or 4π/3

Therefore, x = {0, π/3, π, 4π/3}.

Answer:

The value of f(x) - g(x) is:

f(x) - g(x) =  2x² + 6x - 4

Step-by-step explanation:

Given

f(x) = 3x² + x - 3

g(x) = x² - 5x + 1

To determine

f(x) - g(x)

Using the formula

f(x) - g(x) =  3x² + x - 3 - ( x² - 5x + 1)

              = 3x² + x - 3 - x² + 5x - 1

              = 2x² + 6x - 4

Therefore, the value of f(x) - g(x) is:

f(x) - g(x) =  2x² + 6x - 4

I was at the store, and saw two sizes of avocados being sold. The smaller size sold for $0.92 each. For what prices would the larger avocado be a better deal?

Answers

Answer:

Large avocados should cost $ 1.83 or less to be a good deal.

Step-by-step explanation:

Since there are two types of avocado in the store, some small at $ 0.92 and others larger, to determine at what price large avocados would be a good deal, an equivalence must be established in this regard:

Thus, if two small avocados are equal to one large, buying two small avocados at $ 0.92 the total price would be $ 1.84. Therefore, any large avocado that sells for less than $ 1.84 would be a good deal. Thus, large avocados should cost $ 1.83 or less to be a good deal.

What part of the total earnings was from the commission?

$1038 - $675 = $363

She made $363 in commissions.

The commissions are 8.75% of the sales.

Let sales = x.

0.0825x = 363

Divide both sides by 0.0825

x = 4400

The graph shows a journey in a car. Which of the statements most likely describes the journey at the portion of the graph labeled K?

a. The car travels the same distance per unit of time because the portion shows a linear, increasing function.

b. The car travels different distances per unit of time because the portion shows a linear, increasing function.

c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

d. The car travels the same distance per unit of time because the portion shows a nonlinear, increasing function.

Answers

Answer:

c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

Step-by-step explanation:

We are given the graph of a function of the distance in function of the time.

We want to study the graph during the part of the graph labeled K, which is non-linear, meaning that the accelaration is not constant. This means that the car travels different distances per unit of time, and the correct answer is:

c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

To find:

The rate of change the given linear function.

Solution:

From the given graph it is clear that the line passes through the points (0,1) and (1,-1). So, rate of change is

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

[tex]m=\dfrac{-1-1}{1-0}[/tex]

[tex]m=\dfrac{-2}{1}[/tex]

[tex]m=-2[/tex]

Therefore, the rate of change of the given linear function is -2. Hence, the correct option is A.
