Jennifer started with $50 in her savings account. Each week she withdrew $10. The amount of money in her savings account after x weeks is represented by the function f(x) = 50 - 10x. Find the intercepts

Answers

The value of the intercepts are;

⇒ x = 5

⇒ y = 50

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The amount of money in her savings account after x weeks is represented by the function is,

⇒ f (x) = 50 - 10x

Now,

Find the intercepts as;

The function is,

⇒ f (x) = 50 - 10x

Put x = 0,

⇒ f (x) = 50 - 10 × 0

⇒ f (x) = 50

⇒ y = 50

And, Put y = 0;

⇒ f (x) = 50 - 10x

⇒ 0 = 50 - 10x

⇒ 10x = 50

⇒ x = 5

Thus, The value of the intercepts are;

⇒ x = 5

⇒ y = 50

Find tan-1 1.4281 to the nearest degree.
a. 10°
b. 55°
C. 5°
d. 35°

Answers

Answer:

\:x=55^(\circ \:\:)

Therefore, option 'b' is correct.

Step-by-step explanation:

Let x be the angle

  • tan x = 1.4281

determining the \tan ^(-1)\left(1.4281\:\right)

\:\tan \:x\:=1.4281\:

x=\tan ^(-1)\left(1.4281\:\right)

\:x=55^(\circ \:\:)

Therefore, option 'b' is correct.
