Function: y=3 sin(x) + 5
Range: 2 sy<8
How can you look at the function and know what the
range is?

Answers

Answer:

see explanation

Step-by-step explanation:

The function has a maximum value when sinx = 1 , then

y = 3(1) + 5 = 3 + 5 = 8

The function has a minimum value when sinx = - 1, then

y = 3(- 1) + 5 = - 3 + 5 = 2

Thus

range is 2 < y < 8

simplify -16a⁴+8a³-4a²÷4a²​

Hi can anyone help me with this question without the use of calculators please?

Answers

Answer:

[tex]\frac{11}{6}[/tex] units

Step-by-step explanation:

To find the x- intercepts let y = 0 , that is

6x² - 7x - 3 = 0 ← in standard form

(3x + 1)(2x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = - [tex]\frac{1}{3}[/tex]

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Find the difference of the 2 x- intercepts using absolute value

distance = | [tex]\frac{3}{2}[/tex] - (- [tex]\frac{1}{3}[/tex] ) | = | [tex]\frac{3}{2}[/tex] + [tex]\frac{1}{3}[/tex] | = | [tex]\frac{11}{6}[/tex] | = [tex]\frac{11}{6}[/tex]

Problem 5

Answer:  $490

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

Explanation:

When we increase some value by 7%, we are effectively multiplying by 1.07

Note how 100% + 7% = 107% = 1.07

The 1.07 multiplier is then handy to use algebra to find the cost before tax is added

x = cost before tax

1.07x = cost after tax

1.07x = 524.30

x = 524.30/1.07

x = 490

Before tax, the water heater cost $490.

If we apply a 7% tax, then we pay 7% of 490 = 0.07*490 = 34.30 dollars on top of the $490 to get 490+34.30 = 524.30 which matches with the instructions. So our answer is verified.

Or you could use the 1.07 multiplier shortcut to see that 1.07*490 = 524.30

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

Problem 6

Answer:  $1301.12

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

Explanation:

His gross pay is $1750. This is the amount he earned before any taxes are applied. The items of Medicare, Social Security, and Federal Withholding Income Tax, are all various taxes that Ian has to pay. So his gross pay will be reduced to some smaller value to get the net pay.

To find the total amount of taxes deducted from his paycheck, we add up the tax percentage values to get: 1.45+6.2+18 = 25.65

This means Ian is taxed at a total rate of 25.65% of his gross pay, and he has to pay 0.2565*1750 = 448.875 = 448.88 dollars to the government. This leaves 1750-448.88 = 1301.12 dollars left over for his net pay.

A slightly alternative way is to note how if Ian pays 25.65% of his gross pay, then he's left with 100% - 25.65% = 74.35% of his paycheck, and 0.7435*1750 = 1,301.125 which would round down to 1301.12

I'm rounding up when it comes to determining the amount of tax to pay, while rounding down any amount Ian has left over for his net pay. This ensures that we consider the worst-case scenario.

Lyle bought a baseball card for $800. If the value of the card decreases by 1.5% each year, find the value of the card after 12 year
A)615.92
B)642.85
C)667.31
D)683.72

Answers

Answer:

FV= $669.11

Step-by-step explanation:

Giving the following information:

Purchase price (PV)= $800

Decrease value (d)= 1.5% per year

Number of periods (n)= 12 years

To calculate the value of the card after 12 years, we need to use the following formula:

FV= PV / (1 + d)^n

FV= 800 / (1.015^12)

FV= $669.11

The area of the pacific ocean is approximatley 6.4x10^7 square miles. The area of the gulf of mexico is approximately 10^5 square miles. How many times greater is the area of the pacific ocean than the area of the gulf of mexico

Answers

Answer:

640 times greater

Step-by-step explanation:

Given the following

area of the pacific ocean = 6.4x10^7 square miles

area of the gulf of mexico =  10^5 square miles

Taking the ratio of the distances

pacific ocean/gulf of mexico = 6.4x10^7/10^5

pacific ocean/gulf of mexico = 6.4 * 10^2

pacific ocean/gulf of mexico =640

pacific ocean = 640gulf of mexico

Hence the area of the pacific ocean us 640 times greater than the area of the gulf of mexico

select the statement that does not correctly use probability to describe an event

Answers

Answer:

D

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.

We can then solve the quadratic equation to get the other two factors which are -1/3 and -3/2. You can also graph it and find the roots as well. There isn't a really good method to do this and it is more like trial and error.
