The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C.
Given:
The equation is
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
To find:
The length of the line segment AC.
Solution:
We have,
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
[tex]1.428148=\dfrac{15}{b}[/tex]
Multiply both sides by b.
[tex]1.428148b=15[/tex]
Divide both sides by 1.428148.
[tex]b=\dfrac{15}{1.428148}[/tex]
[tex]b=10.50311[/tex]
[tex]b\approx 10.503[/tex]
In a triangle ABC, the line of line segment AC is b. So,
[tex]AC\approx 10.503[/tex]
Therefore, the length of the line segment AC is 10.503 units.

I don’t understand
I will give brainiest answer
Answer:
Just draw a straight line that intersects or is close with most of the points, in this case the line would be going down meaning it's a negative data point. Now just follow the line and see where it will be when y=2billion. Remember this is not a exact answer your just seeing where most of the points are and predicting based on that.

Answer:
a. yes
b. no
c. no
d. no
e. yes
Step-by-step explanation:
Here, we want to answer yes or no for each of the numbers
a) Yes
If we compare with the general form
y = mx + b
m
is slope and b is y-intercept
so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)
b. No
This is the point-slope form we are trying to
get
Evaluating this, we have that
y-3 = 2x - 6
y = 2x-6 + 3
y = 2x-3
c) NO
Just insert the values and check here
-1 = 2(5) + 3
it does not work
d) No
Substitute
-4 = 2(-5) + 3
e) Yes
This is the point-slope form
y + 3 = 2x + 6
y = 2x + 6-3 = 2x + 3
2 1 a=11start fraction, 1, divided by, 2, end fraction, a, equals, 11 a=a=a, equals Khan Academy
Answer:
a = 5.5
Step-by-step explanation:
Let the expression be written as;
Given 1/2 = a/11, find a
Cross multiply
1×11 = 2×a
11 = 2a
a = 11/2
a = 5.5
The mean age of 12 women in an office is 26 years old.
The mean age of 4 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office
Answer:
27
Step-by-step explanation:
Well, if the mean of 12 people is 26, you can imagine those 12 people are 26, so 26*12=312. Next, you do the same for the 4 men, so 29*4=116. Then you add those 2 numbers together, to get the total of 428. Divide that by the total amount of people in the office which is 428/16=26.75. Rounding up (because the decimal starts with a number above 5) you get that the average age is 27.
Does anyone know 3x=-12?
Answer:
x=-4
Step-by-step explanation:
Divide 3 on both sides since you use the inverse to cancel out each other but you need to do it on both sides to make the equation balance.
3 divided by 3x is x
3 divided by -12 is -4
x=-4

The number of lawns l that a volunteer can mow in a day varies inversely with the number of shrubs s that need to be pruned that day. If the volunteer can prune 6 shrubs and mow 8 lawns in one day, then how many lawns can be mowed if there are only 3 shrubs to be pruned?
Answer: 16 lawns can be mowed if there are only 3 shrubs to be pruned.
Step-by-step explanation:
Equation of inverse variation: [tex]x_1y_1=x_2y_2[/tex]
Given: Number of lawns l that a volunteer can mow in a day varies inversely with the number of shrubs s that need to be pruned that day.
Then, [tex]l_1s_1=l_2s_2[/tex]
Put [tex]l_1=8,\ s_1=6,\ s_2=3[/tex] [To find: [tex]l_2[/tex]]
[tex]8\times6=3l_2\\\\\Rightarrow\ l_2=8\times2=16[/tex]
Hence, 16 lawns can be mowed if there are only 3 shrubs to be pruned.

Write the equation that passes through the point (-2,4) and has a slope of 7
Answer: See explanation
Step-by-step explanation:
Point slope formula = y - y₁ = m (x - x₁)
y - 4 = 7 (x + 2)
y - 4 = 7x + 14
Add 4 to both sides
y = 7x + 18
↑This is also the slope intercept form (y = mx + b)

Irfan incorrectly determined that the equation for the line on the graph is y = 0.5x +5. What is the correct equation for the line?
Answer:
y=-1x+0.5
Step-by-step explanation:
First calculate the slope of the line=y2-y1/x2-x1
Take any two points
1-3/2-1
-2/1
slope=-1
y=mx+c (equation for line)
Take any point and figure the value of c
1=-1x2+c
1/-2=c
c=0.5
y=-1x+0.5
In which quadrant does the point (15,-7) lie?
Answer:
Quadrant 4
Step-by-step explanation:
Quadrant 1: Positive x and Positive y
Quadrant 2: Negative x and Positive y
Quadrant 3: Negative x and Negative y
Quadrant 4: Positive x and Negative y
For point (15, -7), we have a Positive x and a Negative y so it belongs in Quadrant 4.
The quadrant the given point (15,-7) lie is fourth quadrant.
The first quadrant in Cartesian coordinate is given as;
= (x, y)
The second quadrant in Cartesian coordinate is given as;
= (-x, y)
The third quadrant in Cartesian coordinate is given as;
= (-x, -y)
The fourth quadrant in Cartesian coordinate is given as;
=(x, -y)
(15,-7) corresponds to (x, -y)
Thus, the quadrant the given point lie is fourth quadrant.
