Sin N = NM/NR
Cos R = NM/NR

so answer is
D. Cos R and Sin N

we know that

in the right triangle MNR

$Sin(N\°)=Cos(R\°)$

$Sin(56\°)=Cos(34\°)$

Because

$N+R=90\°$

$56\°+34\°=90\°$ --------> by complementary angles

sin ∠MQP= $Sin(56\°)$

therefore

the answer is the option

D. Cos R and Sin N

What is 1/8 of a full rotation

Naya [18.7K]

Answer:

45°

Step-by-step explanation:

If we consider a full rotation to be 360°, we can simply divide 360 by 8 to find 1/8 of a full rotation.

360 ÷ 8 = 45

1/8 of a full rotation is 45°

This would be a big help so plzzz help me =/

The correct order would be:

5/64 x 3, 1/16 x 3, 3/32 x 4, 11/64 x 4, 7/16 x 3, 3/4 x 2, 3/8 x 4, 1 7/8 x 4, 2.25 x 2, 1.5 x 4, 3 3/8 x 3, 3.75 x 3

First we have to take all of the numbers and do the multiplication. It's often easiest to turn them in to decimals so that you have a common form.

3/32 x 4 = 3/8 = .375

3/4 x 2 = 3/2 = 1.5

1 7/8 x 4 = 15/4 = 3.75

2.25 x 2 = 4.5

1.5 x 4 = 6

3/8 x 4 = 3/2 = 1.5

5/64 x 3 = 5/32 = .156

3.75 x 3 = 11.25

1/16 x 3 = 3/16 = .1875

7/16 x 3 = 21/16 = 1.31

3 3/8 x 3 = 81/8 = 10.125

11/64 x 4 = 11/16 = .687

Now we can use those to put in order.

5/64 x 3 = 5/32 = .156

1/16 x 3 = 3/16 = .1875

3/32 x 4 = 3/8 = .375

11/64 x 4 = 11/16 = .687

7/16 x 3 = 21/16 = 1.31

3/4 x 2 = 3/2 = 1.5

3/8 x 4 = 3/2 = 1.5

1 7/8 x 4 = 15/4 = 3.75

2.25 x 2 = 4.5

1.5 x 4 = 6

3 3/8 x 3 = 81/8 = 10.125

3.75 x 3 = 11.25

We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.

From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.

Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.

y = 3x + 15

Answer: y = 3x + 15

Write 3 ½% as a fraction

jeka57 [31]

Answer:

7/200

Step-by-step explanation:

3.5% = 3.5/100 = (3.5/100)×(2/2) = 7/200

_____

The % symbol is a shorthand way to write "/100", so 3.5% = 3.5/100.

An object is thrown upward at a speed of 96 feet per second by a machine from a height of 14 feet off the ground. The height of

liberstina [14]

Answer:

$8t^2 -48 t -7=0$

$x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

Where:

a= 8, b =-48, c = -7 and replacing we got:

$t_1 = \frac{48 - \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = -0.1425$

$t_2 = \frac{48 + \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = 6.142$

And since the time cannot be negative the correct answer for this cae would be t = 6.142 s

Step-by-step explanation:

If the question is: When will the object hit the ground at when the time is how many seconds?

We have the function for the heigth given by:

$h(t) = -16t^2 +96 t +14$

And we want to find the time where $h(t) =0$ so we can set like this the condition:

$0 =-16t^2 +96 t +14$

And we can rewrite the expression like this:

$16t^2 -96 t -14 =0$

We can divide both sides of the equation by 2 and we got:

$8t^2 -48 t -7=0$

And we can use the quadratic equation to solve for t like this:

$x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

Where:

a= 8, b =-48, c = -7 and replacing we got:

$t_1 = \frac{48 - \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = -0.1425$

$t_2 = \frac{48 + \sqrt{(-48)^2 -4(8)(-7)}}{2*8} = 6.142$

And since the time cannot be negative the correct answer for this cae would be t = 6.142 s
