No they are not equivalent 16:4 is like dividing by 4 which is 4:1

4 0

First, simplify the 16:4 ratio.
• 16:4 ÷ 2 = 8:2 ÷ 2 = 4:1

Now, check to see if they're equivalent:
• 3:1 = 4:1 ???
- 3:1 =/= 4:1

So, NO these ratios are not equivalent.

1. A right triangle has a hypotenuse of length 10 yd and one leg of length 2 yd.

Aleonysh [2.5K]

Question 1.

The Pythagoras Theorem states that the square of the hypotenuse is equal to the sum of the square of the two legs.

$h^2=l_1^2+l_2^2$

From the question, the hypotenuse is h=10 yd and one of the legs is 2yd.

This implies that,

$10^2=l_1^2+ {2}^{2}$

Evaluate the exponents

$100=l_1^2+ 4$

Subbtract 4 from each side

$100 - 4=l_1^2$

$l_1^2 = 96$

$l_1= \sqrt{96}$

$l_1 = \sqrt{16 \times 6}$

$l_1 = 4\sqrt{6}$

The correct answer is C

Question 2

We want to solve

${e}^{4x} = 11$

using inverse functions.

The inverse of an exponential function is a logarithmic function.

We take natural log of both sides to get;

$ln({e}^{4x}) = \ln(11)$

Recall that

$\ln( {a}^{n} ) = n \ln(a)$

This means

$4x \ln({e}) = \ln(11)$

Logarithm of the base is 1

$4x (1) = \ln(11)$

$4x = \ln(11)$

Divide both sides by 4

$x= \frac{ \ln(11)}{4} \\x=0.5995\\ x = 0.6$

Hi any help is appreciated. Just wanna graduate:))

Answer: C

<u>Step-by-step explanation:</u>

h · k(x) = 2(3x - 5)(-2x + 1)

= (6x - 10)(-2x + 1)

= -12x² + 6x + 20x - 10

= -12x² + 26x - 10

The probability of a sporting event being cancelled due to rain or lightning is 6/25

<h3>What is Probability?</h3>

This is the likelihood or chance that an event will occur.

Probability = Expected/Total

Given the following

Pr(rain) = 3/5
Pr (lightening) = 2/5

The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5

The probability of a sporting event being canceled due to rain or lightning = 6/25

Hence the probability of a sporting event being cancelled due to rain or lightning is 6/25
