Step-by-step explanation:

edge2020

The correct solution to the problem is that the direction of the resultant force will be approximately 37.33° from the horizontal above the ground.

For 30° Vector of 40 pounds :-

If we divide it in components it will become

40 cos 30° Î + 40 sin 30° Ĵ

40 × ( √3 / 2 ) Î + 40 × ( 1 / 2 ) Ĵ

34.64 Î + 20 Ĵ    ( approximately )

For 45° Vector of 35 pounds :-

If we divide it in components it will become

35 cos 45° Î + 35 sin 45° Ĵ

35 × ( 1 / √2 ) Î + 35 × ( 1 / √2 ) Ĵ

24.75 Î + 24.75 Ĵ    ( approximately )

Now adding both vectors

( 24.75 + 34.64 ) Î + ( 24.75 + 20 ) Ĵ    ( approximately )

59.39 Î + 44.74 Ĵ    ( approximately )

Now Using formula of Tan θ to find the value of θ

( Tan θ = Perpendicular / Base )

Tan θ =  44.74 / 59.39

Tan θ =  0.75    ( approximately )

θ =  Tan⁻¹ (0.75)    ( approximately )

θ =  36.87°    ( approximately )

We are calculated the value of θ as 36.87° which is approximate value as we used a lot of approximations while calculating and, the closest option given is 37.33° which is again an approximate value.
So we can say that the correct answer to this problem is The direction of the resultant force will be approximately 37.33° from the horizontal above the ground.

Answer:

C

Step-by-step explanation:

By the definition of an inverse function, if:

[tex]f(a)=b\text{ then } f^{-1}(b)=a[/tex]

Therefore, the domain of the original function will be the range of the inverse function.

And the range of the original function will be the domain of the inverse function.

We have the original function:

[tex]f(x)=2x^2-5[/tex]

With the domain:

[tex]-\infty<x<\infty[/tex]

Since the domain of the original function is such, then the range of the inverse function is also the same as above.

So, the range of the inverse function is also:

[tex]-\infty< f^{-1}(x)< \infty[/tex]

So, our answer is

C.

Notes:

A, B, and E would automatically be incorrect since we never use ”or equal to” when using the infinity symbol. This is because we can never “equal” infinity.

Answer:

m<4 is the measurement of 20°

and m<1 is the measurement of 33°

and in order to get 127° is to subtract 180° by 127° then that gives you 53° then you ether divide 53° by 180° or, you divide 53° in half, which gives you 33° for measurement 1™ and measurement 4™ gives you 20°

Step-by-step explanation:

The sum of angles m∠1 and m∠4 is 254°.

When two lines meet at a point, the geometrical figure that is formed is called an angle.

Here the taxiway crosses two parallel airplane runways.

Now, the m∠8 = m∠4         (these are corresponding angles)

Again, m∠4 = m∠1               (these are opposite angles)

Therefore, sum of angles m∠1 and m∠4

= (m∠1 + m∠4)

= (m∠8 + m∠8)

= 2 × m∠8

= 2 × 127°

= 254°

20

Hope this helps!

Answer:20

Step-by-step explanation:

Hello!

So first you want to plug in 5 to all of the x

h(5) = 3(5) + 5

No you want to do 3(5)

3(5) = 15

h(5) = 15 + 5

Now you add 15 + 5

15 + 5 = 20

h(5) = 20

So your answer is 20

Your sentence:

16 < 4x

Answer:

Definition: The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Example: From the graph, describe the x and y-intercepts using point notation. The graph crosses the x-axis at x = 1 and x = 3, therefore, we can write the x-intercepts as points (1,0) and (–3, 0). Similarly, the graph crosses the y-axis at y = 3. Its y-intercept can be written as the point (0,3).

Given :

An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each.

Mrs. Tran spent a total of $93 on bandanas at this store.

To Find :

How many cotton bandanas did Mrs. Tran buy.

Solution :

Let, number of cotton and silk bandanas buys are x and y respectively.

So, 7x + 11y = 93

x = (93 - 11y)/ 7

Putting y = 1 , x = 82/7 ( not possible since x can only be positive integer )

Putting y = 4 , x = 7

Therefore, Mrs . Tran will buy 7 cotton bandanas.

Hence, this is the required solution.

Answer:

The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm

Step-by-step explanation:

The lengths of side of the triangle are in ratio 8:9:10

Perimeter of triangle = 108 cm

We need to find length of sides of triangles.

The formula used is: [tex]Perimeter \ of \ triangle = Sum \ of \ all \ sides \ of \ triangle\\[/tex]

The length of side of triangle can be expressed as:

First side= 8x

Second Side =9x

Third Side=10x

So, finding x and then calculate length of each side

[tex]Perimeter \ of \ triangle = Sum \ of \ all \ sides \ of \ triangle\\\\108=8x+9x+10x\\108=27x\\x=\frac{108}{27}\\x=4[/tex]

So, value of x = 4

The length of sides of triangle will be found by putting value of x at each side.

First side= 8x = 8*4 = 32 cm

Second Side =9x= 9*4= 36 cm

Third Side=10x = 10*4=40 cm

So, The lengths of the sides of the triangle in cm are 32 cm, 36 cm and 40 cm

Answer:

m = [tex]\frac{2}{3}[/tex] , b = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Given

2x - 3y = 6 ( subtract 2x from both sides )

- 3y = - 2x + 6 ( divide all terms by - 3 )

y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex] and y- intercept b = - 2

Answer:

y- intercept is (0, -2)

slope is 2/3

Step-by-step explanation:

find 2 points on the line:

2x-3y=6

1/2*(6+3y) =x

if y is 2, x is 6 ((6,2))

if y is 4, x is 9 ((9, 4))

y-intercept is when x = 0.

0-3y=6

y=-2

slope is (y2-y1)/(x2-x1): choose y2 and the corresponding x-coordinate is x2. then the others are the 1's. let's use 4 as y2 which means:

x2 = 9

x1 = 6

y1 = 2

then plug in and solve.

(4-2)/(9-6)

= 2/3

m = 2/3

Hope this helps!
