An angle that is adjacent and congruent to m ∠FTK is, m ∠HTK. So option 1 is true.
Used the concept of angle that states,
An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
T lies on both FH and GJ.
Now by the given figure;
m ∠FTK = 90 degrees
Hence, an angle that is adjacent and congruent to m ∠FTK is,
m ∠HTK = 90 degrees

represents a formula that is shifted up by 3
Answer:
[tex]f(x) = 4 {x}^{2} + 3[/tex]
Step-by-step explanation:
The reason why it is +3 it is because a vertical shift took place which alters the y-interception to be +3 not 0 anymore, making the new formula be the one I've written up there.

Match the graph of the function with the function rule.
A. y = 1 • 4x
B. y = 2 • 4x
C. y = 3 • 10x
D. y = 10 • 4x
Answer:
D. y = 10 • 4x
Step-by-step explanation:
Answer: As seen from the graph, the y intercept is (0,0.5)
plugging this value in each equation:
y=1*4^x
plugging x as 0 and y as 0.5
lhs≠rhs
plugging x as 0 and y as 0.5
lhs = rhs
y= 1/2 x 4x

Answer:
Let's take an example.
If you put the value of x as 1, it gives one.
Even if you put 3.997654, it will give 3.997654.
But for any negative real number, it gives the same number but not with it's negative sign. Like if x =-3/7,
It will give 3/7.
The notation used here means it is the modulus function.......

Step-by-step explanation:
what is 5ax + c = 8.5?
Answer:
a = -0.2cx^-1 + 1.7x^-1
Step-by-step explanation:
Solving for variable a.
Add "-c" to each side of the equation.
5ax + c + -c = 8.5 + -c
5ax = 8.5 - c
Divide each side by 5x.
a = 1.7X^-1 - 0.2cx^-1
Final answer:
a = -0.2cx^-1 + 1.7x^-1

Answer: Choice B
[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]
===============================================================
Explanation:
Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is
c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)
This represents the length of the vector <-4,7>
Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.
The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

The radius of a car wheel is 12 inches. How far will the car travel in 20 revolutions of the wheel?
The distance the car will travel in 20 revolutions of the wheel is 1507.96 inches.
Given that :
Radius of wheel , r = 12 inches
Number of revolutions = 20
The Circumference of the wheel = 2πr
Circumference of the wheel = 2 × π × 12 = 24π
The distance the car will travel after 12 revolutions of the wheel will be :
Number of revolutions × Circumference of wheel
20 × 24π = 480π = 1507.96 inches
