Pythagorean theorem
14.2^2+7.15^2=r^2
r=15.9

SOHCAHTOA
tan(P)=14.2/7.15
Use inverse tangent on calculator to solve
P=tan^-1(1.986)
P=63.27

tan(Q)=7.15/14.2
Q=tan^-1(.504)
Q=26.75

Answer:

it is right angled triangle .. so using pythagoras theorem...

QP^2 = PR^2 + QR^2

r^2 = 7.15^2+14.2^2

r^2= 51.12+201.64

r^2= 252.76

r = 15.89

What is the equation of g(x)? g(x) = 10x â€"" 3 g(x) = 10x 3 g(x) = 10x â€"" 3 g(x) = 10x 3.
STALIN [3.7K]

The equation of g(x) is \rm g(x) = 10^{x-3}.

Given that,

The graphs of f(x) = 10x and its translation, g(x), are shown.

We have to determine,

What is the equation of g(x)?

According to the question,

The given graphs of two functions f(x) and g(x).

The function f(x) is an exponential function and is given by:

\rm f(x) = 10^x

To find the equation for the transformed function g(x).

We could see that the graph of the function g(x) passes through points (3,1), (4,10), (5,100), and so on.

This means that the equation or the expression for the function g(x) is given by:

\rm g(x) = 10 ^{x-3}

Substitute the value of x = 3 in the function g(x),

\rm g(x) = 10 ^{x-3}\\\\g(3) = 10^{3-3}\\\\g(3) = 10^0\\\\g(3) = 1

Substitute the value of x = 4 in the function g(x),

\rm g(x) = 10 ^{x-3}\\\\g(4) = 10^{4-3}\\\\g(3) = 10^1\\\\g(3) = 10

Hence, The equation of g(x) is \rm g(x) = 10^{x-3}.

Two cyclists, 80 miles apart, start riding towards each other at the same time. One cycles three times as fast as the other. If
miv72 [106K]

Answer:

The speed of the faster cyclist is 15 miles per hour

Step-by-step explanation:

Let the speed of the slower cyclist be x miles per hour

The speed of the faster is 3 times this

Mathematically, we have this as 3 * x miles per hour = 3x miles per hour

Now;

distance = speed * time

In 4 hours, the distance covered by the slower will be;

x * 4 = 4x miles

The faster;

3x * 4 = 12x miles

Since they are riding opposite each other, they would have covered a total distance of 80 miles when they meet

Thus, we have that;

12x + 4x = 80

16x = 80

x = 80/16

x = 5

The speed of the faster is;

3x miles per hour

Substitute the value of x here

That will be;

3 * 5 = 15 miles per hour
