In this question we know what the “y-intercept is,so if we go to our graph we can easily just plot the point 7.6 on the y axis of a number line. It also gives you the slope in decimal form so we would want to convert that from 0.2 to 1/5. And remember the slope is how many places you move to get to the next point on the number line. So from the point 7.6 we would move up 1 over 5 to the right because it is a positive number. Your line should run across the upper segment of the number line and your line should make a 20 to 30 degree angle shift

In parallelogram HGJL, HK = c – 7, JK = 3c – 33, and GK = c + 12. What is the length of segment GL? EXPLANATION PLEASE
Alexeev081 [22]

Answer:

50

Step-by-step explanation:

Diagonals of a parallelogram bisect each other.  So HK = JK and GK = LK.

HK = JK

c − 7 = 3c − 33

26 = 2c

c = 13

GK = LK

c + 12 = LK

13 + 12 = LK

25 = LK

GL is the sum of GK and LK:

GL = GK + LK

GL = 2LK

GL = 50

A surveyor sights the top of a building with a handheld range finder. the top of the building is 148 feet 2 inches away. the ang
Leokris [45]

see the attached figure to better understand the problem


we know that

in the right triangle ABC

cos 56°=AC/AB

where

AC is the adjacent side to angle 56 degrees------> the distance from the surveyor to the building

AB is the hypotenuse-----> 148 ft 2 in

56 degrees------> is the angle of elevation

so

cos 56°=AC/AB---------> solve for AC

AC=AB*cos 56°

AB=148 ft 2 in

convert 2 in to ft

1 ft -----> 12 in

x ft------> 2 in

x=2/12-----> x=0.17 ft

AB=148 ft 2 in-----> 148 ft+0.17 ft------> AB=148.17 ft


AC=AB*cos 56°----> AC=148.17*cos 56°------> AC=82.86 ft


convert 0.86 ft to in

0.86 ft=0.86*12-----> 10.32 in

distance AB=82 ft 10 in


the answer is

the distance from the surveyor to the building is 82 ft 10 in

The length of the missing side is: ?m
victus00 [196]

Answer:

85 ft

Step-by-step explanation:

for all right triangles, triangles with a 90 degree angle, the sides are equal to a^{2} + b^{2} = c^{2} where c is the hypotenuse, or the longest side.

so... 40^{2} + 75^{2} = c^{2}

7225 = c^{2}

c= 85

How do I solve this math problem?
Nat2105 [25]

Answer: 4x² + 4x - 2 - \frac{3}{2x+3}

<u>Step-by-step explanation:</u>

You can use either synthetic or long division.  I am using synthetic division:

2x + 3 = 0   ⇒   x = -\frac{3}{2}

 -\frac{3}{2}   |    4    10    4    -6

       <u>|    ↓    -6    -6    3 </u>

            4     4    -2   -3  ← <em>-3 is the remainder</em>

            ↓     ↓     ↓

           4x² +4x  -2  ← <em>factored polynomial</em>
