Answer:

n = 62 + x

Step-by-step explanation:

From the problem given, it is clear that the orange has LESS calories than a nectarine. <em>HOW much less? "x" less.</em>

<em />

Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.

<em>If we let nectarine's calories be n, we can write:</em>

<em>n = 62 + x</em>

I am thinking of a five-digit number where the fifth digit is one-half the fourth digit and one-fourth the third digit. the thir
Natasha_Volkova [10]

solution:

Let the number be ABCDE  

>>The second digit is three times the fourth digit<<

So D is 1,2, or 3 and B is 3,6 or 9.

The number is A3C1E, A6C2E, or A9C3E

>>The second digit is ... five more than the fifth digit.<<

That rules out 3 for B, so B is 6 or 9, and D is 2 or 3.

It also tells us that E is 1 or 4, so that B can be 5 more than it.  

So the number is A6C21 or A9C34  

>>The third digit is ... twice the fourth digit<<  

So C is twice D, which is 2 or 3.  So C is 4 or 6

So the number is A6421 or A9634

>>The third digit is one-half the first digit

So C is 4 because 6 is too large to be half a digit. And so

A has to be 8 so that C=4 can be half of it.

So the number is 86421.

Find the 9th term for 150,60,24
aivan3 [116]

Answer:

a(9) = 150*(0.4)^8 = 0.098304

Step-by-step explanation:

This is a geometric sequence, because each new term is 0.4 times the previous term.

The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).  Here, with a(1) = 150 and r = 0.4, we have:

a(n) = 150*(0.4)^(n - 1), and so

a(9) = 150*(0.4)^8 = 0.098304

4. James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They
Zinaida [17]

$ 159,744.59 will be in the account after 20 years.

Answer: Option A

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

Need to find out the amount present in the account after 20 years. The formula to find out the future value is,

          \text {Future value}=p \times\left(\frac{\left(1+\frac{r}{n}\right)^{n t}-1}{\frac{r}{n}}\right)

Here  

p : amount deposit monthly =$500

r : rate of interest  = \frac{2.75}{100} = 0.0275

n : 12(compound monthly)

t : time =20

By substituting all the given datas in the above equation, we get

    \text { Future value }=500 \times\left(\frac{\left(1+\frac{0.0275}{12}\right)^{240}-1}{\frac{0.0275}{12}}\right)

    \text {Future value}=500 \times\left(\frac{(1+0.002291)^{240}-1}{0.002291}\right)=500 \times\left(\frac{(1.732)-1}{0.002291}\right)

   \text { Future value }=500 \times\left(\frac{0.732}{0.002291}\right)=500 \times 319.511=\$ 159,744.99

On a coordinate plane, a piecewise function has 3 lines. The first line has a closed circle at (negative 3, negative 4) and cont
ICE Princess25 [194]

Answer:Answer:

f(-2) = 2

f(0) = 3

f (4) = -1

Step-by-step explanation:

The equation of the straight line passing through the points (0,3) and (-4,1) is  

⇒ 2(y - 1) = x + 4

⇒ 2y - 2 = x + 4

⇒ 2y = x + 6

⇒  

Again, the equation of the line passing through the points (0,1) and (4,-1) is

⇒ - 2 ( y + 1) = x - 4

⇒ - 2y = x - 2

⇒  

Therefore, the function is defined as

for x ≤ 0 ........... (1) and  

for x > 0 ............ (2)

Therefore, f(-2) = 2 from equation (1).

f(0) = 3 from equation (1)

And f (4) = -1 from equation (2). (Answer)
