What is the measure of angle 2?
25°
42°
46°
88°

Let the base = x

Then the height would be 2x ( twice the length of the base.

Now using the given formula you get:

25 = 1/2 * 2x *x

Multiply 2x by 1/2:

1/2 * 2x = 2x/2

25 = 2x/2 * x

2x/2 = 1x, now you have:

25 = x *x

Multiply x by x:

25 = x^2

Take the square root of both sides:

x = √25

Answer:

-6

Step-by-step explanation:

Let x =1

F(x)=-x^3-2x^2+7x-10

F(1) = - (1)^3 -2(1)^2 +7(1) -10

     = -1 -2 +7-10

    = -3+7-10

   =-6

The output of the given function F(x)=-x^3-2x^2+7x-10 when x equals 1 is -6. We substituted x=1 into each term to calculate this.

The given function is F(x)=-x^3-2x^2+7x-10. To find the output of the function when x equals 1, you substitute '1' in place of 'x' in the equation. So let's calculate:

Now, add all the results together: -1 - 2 + 7 - 10 = -6. Therefore, when x equals 1, the output of the function F(x) is -6.

Final answer:

Using the exponential decay formula, we can find the half-life of the medication from the initial and given 8-hour amounts and then use it to calculate the amount of medication remaining after 10 hours.

Explanation:

To determine the remaining medication after a given number of hours, we will apply the exponential decay formula which accounts for substances with a half-life. Thus, given that there are initially 20 milligrams of the medication and that it decreases to 12 milligrams after 8 hours, we need to calculate the half-life and then use it to predict the amount remaining after 10 hours.

First, finding the half-life 't1/2' can be done using the formula A = A0×2−t/t1/2, where A is the remaining amount (12 mg), A0 is the initial amount (20 mg), and t is the time elapsed (8 hours). Solving for the half-life gives us t1/2 as the unknown in this equation.

12 mg = 20 mg ×2−(8 hours)/t1/2
Reducing this equation, we find that:
t1/2 = 8 hours / (log2(20 mg/12 mg))

After finding 't1/2', we can then determine the amount remaining after 10 hours. The calculation would be as follows:
A = 20 mg ×2−(10 hours)/t1/2

This will give us the final amount of medication left in the system at the 10-hour mark, rounded to the nearest hundredth.

Answer: a lower annual interest fee is better than a low annual fee if you expect to pay your balance in full during most months

Final answer:

A lower annual interest fee is generally better than a low annual fee when it leads to significant savings over time, especially with large amounts or long-term financial products. Interest rates dictate the overall cost of borrowing more than annual fees, particularly for longer terms or larger sums. However, for small, short-term borrowing, a low annual fee might be more beneficial.

Explanation:

When comparing a lower annual interest rate versus a low annual fee, it is essential to consider the specific financial situation and the amount of money involved. As a general rule, a lower interest rate is beneficial when it leads to significant savings on the overall interest paid throughout the loan or credit product term. This is often the case for larger amounts or longer terms where the interest accumulates considerably over time.

For example, financial investors who choose a Certificate of Deposit (CD) earn a higher interest rate compared to savings accounts, as they agree to leave the money deposited for a fixed period, forgoing liquidity. However, if interest rates rise after a loan is made, the existing loan with the lower interest rates becomes less attractive. On the other hand, if the economy experiences a fall in interest rates, the value of the loan with the previously fixed lower rate increases.

Therefore, while a low annual fee can seem attractive, it's the annual interest that ultimately has a more significant impact on the cost of borrowing, especially over longer periods or with larger sums of money. Conversely, for small short-term loans or when the outstanding balance is frequently paid off, a low annual fee might be more advantageous than a lower interest rate, as the interest charges could be minimal.

Answer:

8 inches

Step-by-step explanation:

Surface area of a prism is:

S = 2A + Ph

where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.

The base is a square, so A = s² and P = 4s:

S = 2s² + 4sh

Given that S = 512 and h = 12:

512 = 2s² + 4s(12)

512 = 2s² + 48s

256 = s² + 24s

0 = s² + 24s - 256

0 = (s + 32) (s - 8)

s = -32, s = 8

Since s must be positive, s = 8 inches.

Follow below steps;

To find the length of the square base of the right prism:

First, calculate the lateral surface area: 512 in² = 4s * 12 where s is the side length of the square base.

Then, solve for s: 512 = 48s, s = 512 / 48 = 10.67 in.

Therefore, the length of the square base is 10.67 inches.

2520

Step-by-step explanation:

7×6×5×4×3 = 2520

Imagine □□□□□

For the 1st □, there are 7 choices

For the 2nd □, there are 6 choices (since 1 out of the 7 numbers is already used)

For the 3rd □, there are 5 choices (since 2 out of the 7 numbers are used)

And so on...

The total number of 5-digit numbers that can be formed with the digits 1 to 7, without repetition, is 2520.

Your question pertains to the concept of permutations - the number of ways items can be arranged without repetition. In this case, you are considering how many 5-digit numbers can be formed using the digits 1, 2, 3, 4, 5, 6, 7 without repeating any digit.

A helpful way to think about this is to think of the 5 places for our 5-digit number (i.e., _ _ _ _ _). For the first position, you have 7 choices (the digits 1 to 7) to choose from. Once you have chosen a digit, you are left with 6 choices for the second position, 5 for the third position, 4 for the fourth, and finally 3 for the fifth. So, the total number of 5-digit numbers you can form is 7 × 6 × 5 × 4 × 3 = 2520.

Answer: x=8.5 y=1.5

Step-by-step explanation:

Use the second problem and get X by itself. X= 5y+1. Now plug that equation into the 1st equation.

-(5y+1) +9y =-5.

-5y-1+9y=-5.

-5y+9y= 1+5

4y= 6

Y=1.5

Now that you know what is the value of Y you can plug that into any equation.

5(1.5) +1

7.5+1

X=8.5

For this case we have the following system of equations:

[tex]-x + 9y = -5\\x-5y = 1[/tex]

We clear "x" from the second equation and replace it in the first:

[tex]x = 1 + 5y[/tex]

Answer:

The length of a leg of the triangle = 59.83 cm

Step-by-step explanation:

Points to remember

If a right angled triangle with angles 45°, 45° and 90° then the sides are in ratio 1 : 1 : √2

It is given a right angled triangle with  45°, 45° and 90° and hypotenuse = 84.6 cm

To find the length of a leg

Let 'x' be the length of each leg,

From the figure we can write,

1: 1 :  √2 = x : x : 84.6

Therefore x = 84.6/√2

 = 59.83 cm

Therefore the length of a leg of the triangle = 59.83 cm

ANSWER

59.82

EXPLANATION

The given right angle is an isosceles right triangle.

Let the length of a leg be x cm.

Then by the Pythagoras Theorem,

[tex] {x}^{2} + {x}^{2} = 84.6 ^{2} [/tex]

[tex]2 {x}^{2} = 7157.16[/tex]

Divide both sides by 2.

[tex]{x}^{2} = \frac{7157.16}{2} [/tex]

[tex]{x}^{2} = 3578.58[/tex]

Take positive square root of both sides to get,

[tex]x = 59.82123369[/tex]

Hence the length of a leg is 59.82 to the nearest hundredth.

Therefore, there are 108,000 female officers in the U.S.

Answer: 108,000

Step-by-step explanation:

In 2014, 900,000 sworn law enforcement officers who were serving in the United States and 12% of those officers were female. To find the number of females that were law enforcement officers, we multiply the percentage of females by the total number of law enforcement officers. This will be:

= 12% of 900000

= 12/100 × 900000

= 0.12 × 900000

= 108,000

There were 108,000 females as law enforcement officers serving in the United States.
