If sec(A) = 4/3, then the value cot(A) is [tex]cot(A)=\frac{3\sqrt{7}}{7}[/tex]
The given trigonometric identity is:
[tex]sec(A)=\frac{4}{3}[/tex].........................(*)
Note that:
[tex]sec(A)=\frac{Hypotenuse}{Adjacent}[/tex].........................(**)
Comparing (*) and (**)
Hypotenuse = 4
Adjacent = 3
Find the opposite using the Pythagoras theorem
Hypotenuse² = Opposite² + Adjacent²
4² = Opposite² + 3²
Opposite² = 4² - 3²
Opposite² = 16 - 9
Opposite² = 7
Opposite = √7
cot(A) = Adjacent/Opposite
cot(A) = 3/√7
Rationalize the expression

Mr. Cooper determined functions to represent his distance traveled in miles, d, in terms of the number of hours, 1, of driving on two types of
highways. He found that on a state highway the function was d = 45t, and on a U.S. highway, the function was d = 601.
If Mr. Cooper drove for 1.5 hours on each type of highway, how much farther did he drive on the U.S. highway than on the state highway?

Evaluate the following
expression using x = 5:

[tex] \huge\color{skyblue}\boxed{\colorbox{black}{Answer ☘}}[/tex]
Let's substitute x with 5 to find the value of given expression ~
[tex] \sf3[(3 \times 5) + 5][/tex][tex] \sf3(15 + 5)[/tex][tex] \sf3(20)[/tex][tex] \sf60[/tex]The value of the expression is 60.
What is the value of the expression?
According to the BODMAS rule, when there is a mathematical expression with a bracket, the terms in the bracket should be solved first. So the value of the expression in the bracket would be solved first.
(3(5) + 5)
(15 + 5)
= 20
The second step is to multiply 20 by 3.
20 x 3 = 60

Solve for X
5-x+6=4
X=3
5-x + 6 = 4
Combine like terms:
11-x = 4
Subtract 11 from both sides
-x = -7
Divide both sides by -1
X = 7
Answer: x = 7
Solve for X
5-x+6=4
Answer:-x = 7
Explanation:-=> 5-x + 6 = 4
=> (5+6)-x = 4
=> 11-x = 4
(subtract both the sides by 11)
=> -x = -7
(divide both the sides by -1)
=> x = 7

Answer:
∠BAC=70°
Step-by-step explanation:
If AB || CD and BC II DE that means the two triangles are congruent or the same, this means ∠BAC°=∠DCE°, ∠ABC°=∠EDC°, and ∠BCA°=∠DEC°. The three angles of a triagle add up to 180°. If ∠DEC=45° and ∠EDC=65°
Total°-(∠DEZ°+∠EDC°)=∠DCE° or ∠ECD°
180°-(65°+45°)=70°
∠BAC°=∠DCE°
Therefore ∠BAC=70°

Write the equation of the line that has slope 1 half and passes through (4, -1).
Answer:
-1 = 1/2*4 + -3 / -1 = 1/2*4 - 3 for slope intercept equations
y + 1 = 1/2(x - 4) for point slope equations
Step-by-step explanation:
Slope intercept formula is y = mx + b where y is the y point, x is the x point on the graph, m is the slope and b is y intercept. For this we know the slope, the x and the y axis. Now all we need to find is the y intercept, for this we would have have to multiply the x axis by the slope and then find the number to complete the equation in this case its 1/2 (slope) and 4 (x axis),
-1 = 2 + b
for this we'd subtract -2 to both sides
-1 -2 = +2 - 2 + b
Which then we'd get,
-3 = b
So our Y intercept is -3
To complete the equation we'd finish it with putting everything together,
-1 = 1/2*4 + -3 or -1 =1/2*4 -3
If it were a point slope equation (y - y₁ = m(x - x₁)) we have the y₁, x₁ and the slope value 1/2, so we have all we need to fill in the point slope equation and here it is,
y + 1 = 1/2(x - 4)
