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

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

I need help with this ASAP!!!!

Yanka [14]

Answer:

Step-by-step explanation:

The distance between two points is found by

d = sqrt( ( x2-x1)^2+(y2-y1)^2

= sqrt( ( 10- -6)^2 + (-4 -8)^2 )

= sqrt( (16^2 + (-12 )^2)

= sqrt(256+144)

= sqrt(400)

= 20

Lady_Fox [76]

Answer:

Step-by-step explanation:

As sample size increase the variability of the estimate of the proportion would decreases ( reduces)

The formula of variance of the estimator of the proportion is as

$
Var(\hat p)=\frac{p*(1-p)}{n}
$

Since the denominator of the formula of the variance of sample proportion is n

so as n increase the variance of it decrease.

The center of the estimate of proportion would same

Because $E(\hat p)=p
$

which does not affect the value of n ( sample size).
