Answer:
the height of the tree to the nearest tenth of a meter is 13.8 meters
Step-by-step explanation:
The computation of the height of the tree is shown below:
Given that
Distance from the tree is 10 meters
And, the angle of elevation of the tree is 54 degrees
Now here we used the trigonometry
[tex]tan \theta = \frac{Height}{distance} \\\\tan 54^{\circ} = \frac{height}{10}[/tex]
So, the height is
= 10 × 1.38
= 13.8 meters
hence, the height of the tree to the nearest tenth of a meter is 13.8 meters

6c + 11 = 2c + 59
answer - 12
Answer:
Yes the answer is 12.
Step-by-step explanation:
6c + 11 = 2c + 59
6c - 2c = 59 - 11
4c = 48
dividing both sides by 4:
c = 12.

Find the value of x (3x+38)5x
Answer:
19
Step-by-step explanation:
3x = -38 + 5x
3x + -5x = -38 + 5x + 5x
3x + -5x = -2x
-2x = -38 + 5x + -5x
5x + 5x =0
-2x = -38 + 0
-2x = -38
-2x / -12 = 38 / -2
x=19

Does the equation y = 7.2x represents a direct proportion?
Answer:
Yes the equation represents a direct proportionStep-by-step explanation:
We are given the expression
[tex]y = 7.2x[/tex]------- expressing the relationship between y and x
one way to know if the expression shows a direct proportionality is to answer the question, does y increase if x increases?
let us plug two values for x and see what happens to y
for x=3
y=7.2(3)
y=21.6
for x=4
y=7.2(4)
y=28.8
for x= 2
y=7.2(2)
y=14.4
From our observations when x increases the value of y increases and vice versa, hence there exist a direct proportionality

Only Line 2 intersects the y -axis at the origin. Only Line 2 intersects the y -axis at the origin. Only Line 1 intersects the y -axis at the origin. Only Line 1 intersects the y -axis at the origin. Neither Line 1 nor Line 2 intersects the y -axis at the origin. Neither Line 1 nor Line 2 intersects the y -axis at the origin. Both Line 1 and Line 2 intersect the y -axis at the origin.
If the terminal side of an angle falls in quadrant IV, then the secant value is?
zero
positive
negative
Answer:
it is positive
Step-by-step explanation:
Secant is just sec which is positive in quadrant 4
If the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .
What is quadrant ?Quadrant is a region defined by the two axes ([tex]x[/tex]-axis and [tex]y[/tex]-axis) of the coordinate system. When the two axes, [tex]x[/tex]-axis and [tex]y[/tex]-axis, intersect each other at [tex]90 ^0[/tex], the four regions so formed are the quadrants. These regions include both positive and negative values of [tex]x[/tex]-axis and [tex]y[/tex]-axis, called coordinates.
We know that,
In trigonometry, trigonometric functions i.e. Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cosecθ, the sign of value of all these trigonometric functions varies in every quadrant.
In first quadrant Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cotθ are positive.
In second quadrant Sinθ and Cosecθ are positive.
In third quadrant Tanθ and Cotθ are positive.
In fourth quadrant Cosθ and Secθ are positive.
So, from the above statements we can say that the value of secant in quadrant [tex]IV[/tex] is positive .
Hence, we can say that if the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .

Answer:
Therefore the answer is B)
Step-by-step explanation:
so we have to find the inverse function.
g(x) = -1/(x-2) +3
y = -1/(x-2) +3
x = -1/(y-2)+3
x - 3 = -1/(y-2)
(x - 3)^-1 = -(y-2)^-1*-1
1/(x-3) = -y+2
1/(x-3) -2 = -y
-1(-y) = -1[1/(x-3) -2]
y = -1/(x-3) + 2
or y = 1/(-x+3) + 2
Matches B)

For a science experiment, Mr. Barrows divides 3/4 cup of salt into small jars, each containing 1/10 cup. If he has 1/7 cup of salt left over, how many jars does he fill? Enter an expression you could use to solve the problem.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Initial cup of salt = 3/4 cups ; divided into small jars
Fraction of salt in small jars = 1/10 cup
Fraction left over = 1/7 cup
Number of jars filled?
The fraction divided into the jars :
Initial amount - left over
3/4 - 1/7
(21 - 4) / 28
17 / 28
Fraction of salt per jar = 1/10
Number of jars filled :
Total fraction divided into jars / fraction of salt per jar :
(17 / 28) ÷ (1 /10)
(17 / 28) * (10 / 1)
170 / 28
= 6.0714
= 6 jars
these are the steps taken to produce a final result

5x-10y= 30
Answer:
x-intercept: 6
y-intercept: -3
Step-by-step explanation:
5x - 10y + 30
Start with: 5x = 30
divide the 5 with 30:
5x = 30
5 5
and 30 divide 5 is 6.
then do: -10y = 30
-10y = 30
-10 -10
30 divide -10 is -3.
