jarptica [38.1K]

Here y=1/2 x=pi/3=60°

y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS

so that point is on curve y=cosx

Problem 11

<h3>Answer: h = 2A/b</h3>

------------------

Explanation:

We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b

A = (1/2)*b*h

2A = b*h

b*h = 2A

h = 2A/b

================================================

Problem 12

<h3>Answers:</h3>

Equation: (n+2)/5 = 14
Solution to that equation: n = 68

------------------

Explanation:

The number n is increased by 2 to get n+2

Then we divide by 5 to get (n+2)/5

This is set equal to 14 to get the equation (n+2)/5 = 14

Solving the equation would look like this

(n+2)/5 = 14

n+2 = 5*14 .... multiply both sides by 5

n+2 = 70

n = 70-2 .... subtract 2 from both sides

n = 68

================================================

Problem 13

<h3>Answer: Not a solution</h3>

------------------

Explanation:

We'll replace every copy of x with -3 and simplify

-2x + 5 > 13

-2*(-3) + 5 > 13

6 + 5 > 13

11 > 13

The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.

Therefore, x = -3 is not a solution.

In a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink f

marusya05 [52]

Answer:

Probability that the person preferred milk as his or her primary drink = 0.3

Step-by-step explanation:

Given -

In a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink for breakfast .

Total no of people is = 18 + 29 + 13 = 60

If a person is selected at random ,

The probability of person preferred milk = $\frac{18}{60}$

The probability of person preferred coffee = $\frac{29}{60}$

The probability of person preferred juice = $\frac{13}{60}$

Probability that the person preferred milk as his or her primary drink =

P ( milk ) = $\mathbf{\frac{No\;of\;favourable\;outcomes}{total\;no\;of\:outcomes}}$

= $\frac{18}{60}$ = 0.3

the relationship between the relative size of an earthquake, S, and the measure of the earthquake on the Richter scale, R, is gi

omeli [17]

Answer:

Relative Size, S, is 1584.89

Step-by-step explanation:

The equation is $R=log_{10}(S)$

Where,

R is the measurement in Richter Scale
S is the relative size of the earthquare

<u>It is given that in Richter Scale, an earthquake measured 3.2, so $R=3.2$ .</u>

<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

$R=log_{10}(S)\\3.2=log_{10}(S)$

<em>Converting to exponential form, we have:</em>

$3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932$

<em>Rounding to nearest hundredth, we have:</em>

$S=1584.89$
