Triangle ABC has a right angle at C. Select all measurements which would mean it has a hypotenuse with a length of 10 units. a.

Delvig [45]

Option d: Angle A is 30 degrees, BC is 5 units

Option e: AC is 8 units, BC is 6 units

Explanation:

The triangle ABC has a right angle at C.

The length of the hypotenuse is 10 units.

The image of the triangle with this measurement is attached below:

Option a: Angle A is 20 degrees, BC is 2 units

$\begin{aligned}\sin 20 &=\frac{2}{h y p} \\h y p &=\frac{2}{\sin 20} \\&=5.8476\end{aligned}$

Since, hypotenuse is 10 units, Option a is not correct answer.

Option b: AC is 7 units, BC is 3 units

$\begin{aligned}A B &=\sqrt{7^{2}+3^{2}} \\&=\sqrt{49+9} \\&=\sqrt{58}\end{aligned}$

Since, hypotenuse is 10 units, Option b is not correct answer.

Option c: Angle B is 50 degrees, BC is 4 units

$\begin{aligned}\cos 50 &=\frac{4}{h y p} \\h y p &=\frac{4}{\cos 50} \\&=6.222\end{aligned}$

Since, hypotenuse is 10 units, Option c is not correct answer.

Option d: Angle A is 30 degrees, BC is 5 units

$\begin{aligned}\sin 30 &=\frac{5}{h y p} \\h y p &=\frac{5}{\sin 30} \\&=10\end{aligned}$

Since, hypotenuse is 10 units, Option d is the correct answer.

Option e: AC is 8 units, BC is 6 units

$\begin{aligned}A B &=\sqrt{8^{2}+6^{2}} \\&=\sqrt{64+36} \\&=\sqrt{100} \\&=10\end{aligned}$

Since, hypotenuse is 10 units, Option e is the correct answer.

Thus, Option d and e are the correct answers.

Chris has a large collection of hockey cards and wants to get of rid of some of his hockey cards. He gives 2 cards away on day 1

WINSTONCH [101]

We define

day--------------------------X
hockey cards away ------------f(X)
He gives 2 cards away ----------------on day 1----------f(X)=2 X=1
He gives 4 cards away ----------------on day 2----------f(X)=4 X=2
He gives 8 cards away ----------------on day 3----------f(X)=8 X=3
the sequence of cards away 2,4,8,16,32,64,128,256,512,1024

f(x) = 2**(x)

The answers are

D Each day corresponds to a unique amount of hockey cards in this sequence.
And B The graph of this sequence would pass the vertical line test.

Each element of the Domain (X = day), relates to a single value of f(x) = number of hockey cards

That is, every value of X must have only one corresponding value of f(x)
(One value of y, for each input X)

This can also be checked by using the vertical line test.

If we plot f(x) and we draw vertical lines in the curve, we can verify that at every input the line intersects only one point of f(x)
