Find x in this right triangle

Answers

Answer 1

Answer:

Since the triangle is right angled, we may use pythagoras theorem to find the third side.

Pythagoras theorem :-

KI^2 + JI^2 = KJ^2

substituting the known values in the formula,

x^2 + 3^2 = 5^2

x^2 + 9 = 25

x^2 = 25 - 9

x^2 = 16

x = √16

x = 4

•°• value of x is 4cm

Answers

Answer:

g=-32

Step-by-step explanation:

We are given that

$3=(g)/(-4)-5$

We have to find the value of g.

$3=(g)/(-4)-5$

$(g)/(-4)=3+5$

Using addition property of equality

$(g)/(-4)=8$

By addition property of integers

$g=8(-4)$

By using multiplication property of equality

$g=-32$

Hence, the value of g=-32

If F(x) = x+ 6 and G(x) = x^4, what is G(F(x))?O
A. A +x+6
B. (X+6)^4
C.x^4+6
D.x^4(x+6)

Answers

ANSWER

B. $(x + 6)^(4)$

EXPLANATION

The given functions are:

f(x)=x+6

and

$g(x)= {x}^(4)$

We want to find

$g(f(x)) = g(x + 6)$

This is the composition of functions, where one function becomes the input of the second function.

We plug in x+6 into the expression for g(x) to obtain,

$g(f(x)) = (x + 6)^(4)$

The correct answer is B.

What is the unit rate of 50 meters over 40.8 seconds

Answers

Answer:

1.23 meter/second

Step-by-step explanation:

unit rate of 50 meters over 40.8 second can be written as $(50)/(40.8)$

= 1.22549 ≈ 1.23 meters per second.

The unit rate is 1.23 meter/second.

To find the unit rate for this you have to divide 50/40.8 to find how many meters per second. so your answer would be 1.22. Hope it helps!!

Cora is graphing the equation y = 12x. She has placed a point on the origin and uses the slope to find 2 more points. Which points does Cora plot on her graph? Choose exactly two answers that are correct. A. (−1, −12) B. (−12, −1) C. (1, 12) D. (12, 1)

Answers

put x = 1
y = 12 (1)
y = 12
so x = 1
y = 12

put x = -1
y = 12 (-1)
y = -12
so x = -1
y = -12

Your correct options are A and C.
