Answer:

5 degrees above Zero = greater than 0 = + 5

3 degrees below Zero = less than 0 = - 3

6 degrees above Zero = greater Than 0 = + 6

2 3/4 degree below Zero = less than 0 = - 2 3/4

-3 ; - 2 3/4 ; + 5 ; + 6

Step-by-step explanation:

5 degrees above Zero = greater than 0 = + 5

3 degrees below Zero = less than 0 = - 3

6 degrees above Zero = greater Than 0 = + 6

2 3/4 degree below Zero = less than 0 = - 2 3/4

The least temperature value implies the coldest while the highest implies the warmest :

Therefore.

Least temperature = - 3 ; then - 2 3/4 ; then + 5 ; then + 6

-3 ; - 2 3/4 ; + 5 ; + 6

Answer:

3x²+4

Step-by-step explanation:

To find the derivative of something with respect to x, for each term multiply the power on the x in that term by the coefficient in the same term, and then lower the x's power by one.

For example, if we had to find the derivative of 2x³, we would first multiply the power on the x (3) by the coefficient (2): 6x³. Then lower the x's power by one: 6x². So the derivative of 2x³ is 6x².

To find the derivative an expression with several terms added together, you just do the same for each terms.

d(x³+4x)/dx

= \(\frac{d}{dx}\) x³+4x

= 3x²+4

Answer:

x=11.34

Step-by-step explanation:

The amount (present value at age 60) that Sandro would neet in his retirement savings account in order to have a monthly income of $1,500 until he is 90 years old, compounded at 4.5% monthly is $296,041.74.

The present value is computed using an online fiance calculator that discounts the future withdrawals (monthly income) for a 360-months period.

End of withdrawal period = 90 years old

Beginning of withdrawal period = 60 years old

The number of years between 60 and 90 = 30 years

N (# of periods) = 360 months (30 years x 12)

I/Y (Interest per year) = 4.5%

PMT (Periodic Payment) = $-1,500

FV (Future Value) = $0

Results:

Present Value (PV) = $296,041.74

Sum of all periodic payments = $540,000 ($1,500 x 360 months)

Total Interest = $243,958.26

Step-by-step explanation:

this question is basically asking you to find the HCF of 30 and 36

step 1 : draw prime factor tree diagrams and write the numbers out as the product if their prime factors

step 2: multiply the prime factors they have in common

30 = 2 x 3 x 5

36 = 2 x 2 x 3 x 3

HCF = 2 x 3 = 6

Answer: 6 rows of lemon trees and 6 rows of lime trees.  

Steps: All you need to do is to find the highest common factor of 30 and 36, which is 6.  

30 divided by 6 is 5 and 36 divided by 6 is 6.  So uncle john can plant 5 lemon trees and 6 lime trees each row. That would make 6 rows of lemon trees and 6 rows of lime trees.

Step-by-step explanation:

Plug in 700 for P0, .02 for r, 12 for n and n, and 7 for 5.

Approx value of the account in 7 years will be 805.10$.

Simple interest and compound interest are the two methods for calculating interest. Simple interest is computed on a loan's principal, or initial loan amount. Compound interest is sometimes referred to as "interest on interest" since it is computed using both the principal and the accrued interest from prior periods.

Given that equation calculates the value, P, of an account with an initial deposit of P0 and an interest rate of r compounded n times per year after t years.

P = P0 (1+r/n)nt

Vanessa deposits $700 in a savings account with an interest rate of 2% compounded monthly. Assuming she neither adds to nor withdraws from the account.

Hence, initial deposit:$700.00

Interest rate:2% yearly

Time:7 years

Compounding: Monthly so n = 12

put these values in the given equation. we will get P = 805.10

Therefore the value of the account in 7 years will be 805.10$.

The interval where function f(x) is negative and greater than 0 is (-∞, -3) U (-1.1, 0)

We have,

The function f(x) crosses the x-axis at (-3, 0), (-1.1, 0), and (0.9, 0), it means that f(x) is negative for x values less than -3, between -1.1 and 0.9, and greater than 0.

Therefore, we can say that:

f(x) < 0 for x < -3 and -1.1 < x < 0.9

And,

The function f(x) has a minimum value of (0, -3) and a maximum value of (-2.4, 17).

This means that f(x) is positive for x values greater than -2.4. Therefore, we can say that:

f(x) > 0 for x > -2.4

Now,

Combining these inequalities, we can say that f(x) is negative over the intervals (-∞, -3) and (-1.1, 0.9), and positive over the interval (-2.4, ∞).

So,

The interval where f(x) is negative and greater than 0 is:

(-∞, -3) U (-1.1, 0)

Thus,

The interval where f(x) is negative and greater than 0 is (-∞, -3) U (-1.1, 0)

283.Modifying Above 3 with bar is the answer

The number is 2, obtained by setting up and solving a linear equation using basic algebraic operations.

To find the unknown number, we would apply basic algebraic equations. Let's represent the number as "x." According to the problem:

The number multiplied by 10: 10x

That product added to 5: 10x + 5

The sum is equal to the product of 5 and 5: 10x + 5 = 5 * 5

Now, solve for "x":

10x + 5 = 25

Subtract 5 from both sides:

10x = 20

Divide by 10:

x = 2

So, the number is 2.

Using the normal distribution, it is found that there is a 0.284 = 28.4% probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem, for each variable, \(\mu_G = 3.25, \sigma_G = 0.91, \mu_H = 4.51, \sigma_H = 2.02\)

For the subtraction, we have that:

\(\mu_D = \mu_G - \mu_H = 3.25 - 4.51 = -1.26\)

\(\sigma_D = \sqrt{\sigma_G^2 + \sigma_H^2} = \sqrt{0.91^2 + 2.02^2} = 2.2155\)

The probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices is P(D > 0), which is 1 subtracted by the p-value of Z when X = 0.

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{0 - (-1.26)}{2.2155}\)

\(Z = 0.57\)

\(Z = 0.57\) has a p-value of 0.7157.

1 - 0.715 = 0.284

0.284 = 28.4% probability that a randomly selected package of grapes weighs more than a  randomly selected package of honeydew slices.

to solve for m

distribute into parentheses

176 = -16 - 24m

Answer:

m∠F = 90°

Step-by-step explanation:

By the property of a kite,

"One pair of the opposite angles are congruent"

m∠E ≅ m∠G

m∠E = m∠G = 113°

Sum of the interior angles of a polygon = (n - 2) × 180°

Here, n = number of sides of the polygon

For a kite, n = 4

Therefore, sum of the interior angles of the given kite = (4 - 2) × 180°                                                                          

                                                                                          = 360°

Therefore, m∠E + m∠F + m∠G + m∠H = 360°

113° + m∠F + 113° + 44° = 360°

m∠F = 360° - 270°

m∠F = 90°

Step-by-step explanation:

Multiply your numerator together, which will give you 72. 72/-2 = -36.

Answer:

-36

Step-by-step explanation:

(-9)*(-8) = + 72        1. As we know, a negative * a negative, will equal a positive.  So obviously, -9 * -8 equals 72,

72/-2 = -36

2. Because a negative divided by a positive will always be a negative, 72/-2 will be -36 by just dividing the two.
