Step-by-step explanation:

Answer:

The angle of elevation is equal to 68.2 degrees

Step-by-step explanation:

As you can see from the image below we are trying to find the angle on the bottom right.

We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.

sin x = 13/14

divide:

sin x = 0.9285714286

now we need to use sin^-1

sin^-1 (0.9285714286) = 68.21321071

Round 68.21321071 to the nearest tenth:

68.2

The angle of elevation is 68.2 degrees!

Answer:

[tex]\theta \approx 68^\circ[/tex]

Step-by-step explanation:

Trigonometry

The ladder, the wall, and the ground form a right triangle, where the ladder is the longest side (hypotenuse).

The trigonometric ratios stand on right triangles and can be used to relate side lengths with angles.

The angle of elevation, formed by the ladder and the ground has the height of the wall as the opposite side. Thus we can use the sine ratio, defined as:

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \sin\theta=\frac{13}{14}[/tex]

Solving:

[tex]\displaystyle \theta=\arcsin \frac{13}{14}[/tex]

Calculating:

[tex]\mathbf{\theta \approx 68^\circ}[/tex]

Step-by-step explanation:

The first blank is the slope, the second one shows the y-intercept. You are welcome

Answer:the slope is negative is the one with the x , -3/2 so that means the top of the line points to the top left

Start with -3 which on the y axis start on -3 go down thats the first dot point then do slope which is -3 down /2 right the opposite start again on -3 on the y go up 3 and 2 to the left connect points

Answer:

60°

Step-by-step explanation:

Complementary angles add to 90°, so if x is double its complement, then x + (1/2)x = 90. Doing the algebra gets you to x = 60. You know that answer is correct because 60 is double 30, which is its complement.

Answer:

100, 70, 80, 56

Explanation:

Look at attached image!

In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

The number in the 4 sections are 100, 80, 70, and 56.

A 2 x 2 array that shows the problem 18 x 17.

2 x 2 array has four blockers or magic quadrants, the matrix diagram is a simple square divided into four equal quadrants.

18 = 10 +8

17 = 10 +7

18 x 17 = 306

In the 2 x 2 array : 100+80+70+56 = 18 x 17 = 306

Therefore, In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

Answer: If the air-plane travels 1020 km in one hour, then it will cover 4250 km in 25/6 hours.

The formula which relates distance, speed, and time is given by d = rt, where d is the distance traveled, r is the rate of travel or the speed, and t is the time traveled. To find out the distance an aircraft will travel in t = 25/6 hours, we must first find out the speed r of the aircraft in kilometers per hour (km/hr) as shown:

d = rt

1,020 km = r(1 hr)

(1,020 km)/(1 hr) = [r(1 hr.)]/(1 hr)

1,020 km/hr = r(1 hr./1 hr)

1,020 km/hr = r(1)

r = 1,020 km/hr

Now, calculating the distance the aircraft will travel in t = 25/6 hours, we have:

d = rt

= (1,020 km/hr)(25/6 hr)  

= (1,020)(25/6) km

= (1,020/6)(25) km

= (170)(25) km

= 4,250 km

Answer:

4250 km

I think A or C would be the answer! Hope this helped a little!!

The property illustrated by the equation 6 + (4 + x) = 6 + (x + 4) is the commutative property of addition.

The commutative property of addition states that the order in which numbers are added does not affect the result. In this equation, both sides of the equation involve adding numbers, and the numbers being added are the same: 6, 4, and x.

The equation shows that regardless of whether we add 4 and x first or x and 4 first within the parentheses, the final result will be the same. The commutative property of addition allows us to freely rearrange the order of the terms being added without changing the overall sum.

Therefore, The property illustrated by the equation 6 + (4 + x) = 6 + (x + 4) is the commutative property of addition.

Answer:

The function g(x) has a greater value when x = 3. The function g(x) will be 7 when x = 3 while the function f(x) is will be 5

Step-by-step explanation:

For the function f(x), when x = 3, you get the equation f(x) = 2(3) - 1. Two times three equals six, so the equation can be simplified to f(x) = 6 - 1. Six minus one equals five, so f(x) = 5 when x = 3.

For the function g(x), when x = 3, you get the equation g(x) = 4(3) - 5. Four times three equals 12, so the equation is now g(x) = 12 - 5. 12 minus five equals seven, so g(x) = 7 when x = 3.

Answer:

c = 6P

Step-by-step explanation:

equation format: c = mP

c = the total cost Donna pays

m = the cost per pound of chocolate(6)

P = the amount of pounds Donna buys

Since we know the cost per pound is $6, we can input it into the equation format:

c = 6P

Now we have an equation that represents the total cost (c) that Donna pays for P pounds.

Let C = total cost that Donna pays.

Donna buys P pound at $6 per pound tells me to multiply.

C = 6P.

Answer:

Option (4)

Step-by-step explanation:

To solve this problem we will satisfy the polynomials given in the options with the input-output values given in the table.

Lets take a point (4, 40),

Option (1),

f(h) = h² + 4h + 80

40 = 4² + 4(4) + 80

40 = 16 + 16 + 80

40 = 112

False.

Therefore, table doesn't represent the polynomial given in option (1).

Option (2)

f(h) = 5h²- 5h + 13

40 = 5(4)² - 5(4) + 13

40 = 80 - 20 + 13

40 = 73

False.

Therefore, table doesn't represent the polynomial given in option (2).

Option (3)

f(h) = h³ + 50h² + 13

40 = 4³ + 50(4)²+ 13

40 = 64 + 800 + 13

40 = 873

False.

Therefore, table doesn't represent the polynomial given in option (3).

Option (4)

f(h) = 5h³- 50h²+ 13h

40 = 5(4)³ - 50(4)²+ 130(4)

40 = 320 - 800 + 520

40 = 840 - 800

40 = 40

True.

Therefore, given table represents this polynomial.

Option (4) will be the answer.
