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.

Answer:
please mark me as brianlist
Step-by-step explanation:
a. log_a 64 = log_a 4³ = 3 log_a 4
= 3 (1.585) = 4.755
b. log_a 1/16 = log_a 4`² = -2 log_a 4
= -2(1.585) = -3.17
c. log_a 36 = log_a 4×9 = log_a 4 + log_a 9
= 1.585 + log_a 9
Name an angle or angles in the diagram shown to the right described by the following. Note that T lies on both FH and G).
adjacent and congruent to ZFTK
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
Therefore, option 1 is true.

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:
D) y= 10*4^x
Step-by-step explanation:
Replace each function with x = 0
A)
B)
C)
D)
If you check the graph with x = 0, the value of y is between 8 and 12 so the only probably answer acoording to the alternatives is D) which gives y = 10 when x = 0

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.
