Step-by-step explanation:
254.16inches
Step-by-step explanation:
Using sine rule
g/sin25=510/sin122
Sin25=0.4226
Sin122=0.8480
g/0.4226=510/0.8480
Cross multiply
0.8480g=0.4226 x 510
0.8480g=215.526
Divide both sides by 0.8480
g=215.526/0.8480
g=254.16
The length of g is 70 inches.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
ΔGHI, h = 13 inches, i = 77 inches and ∠G=170°.
We need to find the length of G
Cosine rule: (for all triangles)
c²=a²+b²-2abcos(C)
=13²+77²-2.13.77.cos(175)
=169+5929-2002cos(175)
=6098-2002(0.598)
=6098-1197.2
c²=4901
Take square root on both sides
c=70.01
G=70.01
Hence, the length of g is 70 inches.

Angle DFG and Angle JKL are complementary angles. mAngle DFG= x+8.0 and mAngle JKL= x- 5.8 Find mAngle JKL
Answers
Answer:
m<JKL = 38.1
Step-by-step explanation:
We are given 2 angles, <DFG and <JKL, which are complementary angles, also that m<DFG = x+8.0 and m<JKL = x-5.8
Complementary angles are angles that add up to 90.
This means that m<DFG plus m<JKL is equal to 90.
As an equation, that would be:
m<DFG + m<JKL = 90
We can substitute m<DFG and m<JKL with their measures.
x + 8.0 + x - 5.8 = 90
Combine the x's.
2x + 8.0 - 5.8 = 90
Subtract 5.8 from 8.0.
2x + 2.2 = 90
Subtract 2.2 from both sides
2x = 87.8
Divide both sides by 2.
x = 43.9
We found the value of x, but we aren't done yet. The question wants us to find the measure of <JKL.
Remember that m<JKL=x-5.8
So, replace 43.9 as x and subtract 5.8 from it.
m<JKL = x-5.8 = 43.9 - 5.8 = 38.1

What is an equation of the line that passes through the point (2,-5) and is parallel
to the line 6x +y = 6?
Answers
Answer:
y = -6x + 7
Step-by-step explanation:
In this question, we need to find the equation of a line with the given information.
We know that the line passes through (2, -5).
We also know that the line is parallel to the line 6x + y = 6, which means that it has to have the same slope.
To make it simpler to understand, we can change the equation into slope format:
y = -6x + 6
This means that our new line should have a slope of -6.
With the information above, we can plug in our new values to get the y-intercept of our equations, since we don't have that information.
Plug in your slope and coordinates to the y = mx + b equation and solve for b:
-5 = -6(2) + b
-5 = -12 + b
Add 12 to both sides.
7 = b
Our y-intercept would be b.
Now, we can plug in all our information to get our new equation:
y = -6x + 7
Your answer would be y = -6x + 7
Write the equation of the line through (2,4) with a slope of 2/3 in Point Slope Form
Answers
Answer:
y - 4 = 2/3(x - 2)
Step-by-step explanation:
The format for point-slope form is: y - y₁ = m(x - x₁)
where m is the slope, x₁ is the x-coordinate and y₁ is the y-coordinate.
In (2,4), 2 is the x-coordinate and 4 is the y-coordinate.
The slope is 2/3.
When you plug in the values, you get:
y - 4 = 2/3(x - 2)

Write an equation of the line that passes through (3, 7) and is parallel to the line shown. (1, 4) (- 2, - 2)
Answers
Answer:
y=2x+1.
Step-by-step explanation:
You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.
When a patient with hypertension takes a particular type of blood pressure medication, the effects on the systolic pressure, S(t), can be measured by the following piecewise defined function: S of t is equal to the piecewise function of 145 minus 6 times t if 0 is less than or equal to t is less than or equal to 5 and 115 if 5 is less than t is less than 9 and 52 plus 7 times t if 9 is less than or equal to t is less than or equal to 12 where t is the time, in hours, since taking the medication. Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 7 a.m., in which interval will their systolic pressure be lowest?
a. 1 p.m. to 3 p.m.
b. 4 p.m. to 6 p.m.
c. 7 a.m. to 9 a.m.
d. 10 a.m. to 12 p.m.
HELP!!! PLEASE!!! ASAP!!! PRE-CALCULUS!!!
Answers
Finding the numeric values of the piecewise function, the blood pressure will be lowest in the following time:
a. 1 p.m. to 3 p.m.
How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.
In this problem, we have a piecewise function, that is, a function with different definitions based on the input, in which:
The input t is the time in hours after 7 am.The output S(t) is the blood pressure in t hours after 7 am.The numeric values are calculated next, looking at the definition for each value of t.
S(0) = 145 - 6(0) = 145.S(1) = 145 - 6(1) = 139....S(5) = 145 - 6(5) = 115.S(6) = S(7) = S(8) = 115.S(9) = 52 + 7(9) = 115.S(10) = 52 + 7(10) = 122.S(11) = 52 + 7(11) = 129.S(12) = 52 + 7(12) = 136.The lowest values are for t between 6 and 8, that is, between:
7 a. m. + 6 hours = 1 p.m.7 a. m. + 8 hours = 3 p.m.Hence option a is correct.

Your friend first multiplies each side of 1/2 (x-9)=3/4 (5x+1) by 4 when solving the equation. Why might your friend do this?
Answers
Answer:
x = (-39)/11
Step-by-step explanation:
Solve for x:
x - 9 = (3 (5 x + 1))/4
Multiply both sides by 4:
4 (x - 9) = (4×3 (5 x + 1))/4
(4×3 (5 x + 1))/4 = 4/4×3 (5 x + 1) = 3 (5 x + 1):
4 (x - 9) = (3 (5 x + 1))
Expand out terms of the left hand side:
(4 x - 36) = 3 (5 x + 1)
Expand out terms of the right hand side:
4 x - 36 = (15 x + 3)
Subtract 15 x from both sides:
(4 x - 15 x) - 36 = (15 x - 15 x) + 3
4 x - 15 x = -11 x:
-11 x - 36 = (15 x - 15 x) + 3
15 x - 15 x = 0:
-11 x - 36 = 3
Add 36 to both sides:
(36 - 36) - 11 x = 36 + 3
36 - 36 = 0:
-11 x = 3 + 36
3 + 36 = 39:
-11 x = 39
Divide both sides of -11 x = 39 by -11:
(-11 x)/(-11) = 39/(-11)
(-11)/(-11) = 1:
x = 39/(-11)
Multiply numerator and denominator of 39/(-11) by -1:
Answer: x = (-39)/11
