Answer:
its 3 3/4 :)
Step-by-step explanation:
Two unidentified flying discs are detected by a receiver. The angle of elevation from the receiver to each disc is 39.48 degree. The discs are hovering at a direct distance of 826m and 1.296km from the receiver. Find the difference in height between the two unidentified flying discs, to the nearest meter.
Answer:
The answer is "298.83 m"
Step-by-step explanation:
Its gap from its transmitter from each disc comprises of 2 triangles. Its horizontal segment via disc to vertical, and longitudinal segment. Disk height, h, is parallel to a horizontal disc Wink including its line across recipient to disc or horizontal 39. 48^{\circ}
[tex]\to 39. 48^{\circ} = \frac{h_1}{826 \ m}\\\\ \to 826\ m (\ sin 39. 48^{\circ} ) = h_1\\\\ \to 525.18 = h_1\\\\[/tex]
if:
[tex]\to \sin 39. 48^{\circ} = \frac{h_2}{1.296 \ km}\\\\ \to \sin 39. 48^{\circ} (1296 \ m) = h_2\\\\ \to 824.01 = h_2\\\\\to h_2 - h_1 = 824.01 - 525.18\\\\[/tex]
[tex]= 298.83 \ m[/tex]

3. What is the slope of a line with the
equation y = 5x + 2?
/5
Answer:
5
Step-by-step explanation:
this is in slope intercept form or y=mx+b
m represents slope and m is 5
Answer: [tex]m = 5[/tex]
The slope of the line in this equation is 5.
y = mx + b
the m multiplied with x is the slope.

Answer:
6. 2
7. (-3/2)
Step-by-step explanation:
6. 4x - 2y = 8
-4x -4x
-2y = -4x + 8
y = 2x + 4
y = 2/3x + 1
reciprocal of 2/3 is -3/2
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(6)
Given
4x - 2y = 8 ( subtract 4x from both sides )
- 2y = - 4x + 8 ( divide all 3 terms by - 2 )
y = 2x - 4 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
Slope of parallel line is m = 2
----------------------------------------------------------
(7)
Given
y = [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]

Misty must pack 365 candles into 15 boxes. Each box must contain an equal number of candles. How many candles does she have left over? (use long division to find the remainder)
A) 1
B) 3
C) 5
D) 7
The answer is 5 because you can fit 365 into 15 24 times and then that would equal 360 and then you have 5 left over.
15x24=360 365
- 360

Answer:
C
Step-by-step explanation:
10 can go into 365 10 times leaving 5 left over.

Write the equation -11x+9y=-12 in slope intercept form. what are the slope and y intercept?
Answer:
Step-by-step explanation:
first solve for y (or x) I chose y.
-11 + 9y = -12
(-11) - (-12) = 1
9y = 1
9/1 = 1
y=1, now for x.
-11x + 9 = -12
-12 - 9 = -21
-11x = -21
-21/-11 = -32
x = -32.
Identify h (x) = [x] + 4
A.
direct variation function
B.
constant function
C.
absolute value function
D.
greatest integer function
Answer:A- direct variation function
Step-by-step explanation:
h(x) = [x] + 4 is in A. direct variation function as we increase the value of x the function h(x) will also increase and vice versa.
What is proportion?Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, h(x) = [x] + 4, as we increase the value of x the function h(x) will also increase and vice versa.
So, h(x) = [x] + 4 is in direct variation.
