3. Apply the projectile formula to a real-world situation.

Answers

Answer 1
1. Quadratic equations have the highest degree of 2. Therefore, the maximum amount of solutions can be 2 or unreal. The graphs with 2 solutions would cross over the x-axis twice, 1 solution would touch the x-axis once and 0 solutions would not touch the x-axis.

Laura drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 8 hours. when laura drove home, there was no traffic and the trip only took 6 hours. if her average rate was 16 miles per hour faster on the trip home, how far away does laura live from the mountains

Answers

Final answer:

To find the distance Laura lives from the mountains, calculate her average speed when driving to the mountains and use the time taken during the trip. With the given speeds and travel times, the distance can be determined using a simple equation.

Explanation:

To find the distance Laura lives from the mountains:

Let x be Laura's average speed when driving to the mountains.Since Laura drove 16 mph faster on the way home, her speed returning was x+16 mph.Distance to mountains = x * 8 (hours) and distance from mountains = (x+16) * 6 (hours).Set up the equation: x * 8 = (x+16) * 6 to solve for x.Once x is found, the distance Laura lives from the mountains can be calculated as x * 8.

Why is it important to take note of skipped check numbers?

A. Skipping a check wastes the check and will end up costing money.
B. Locating skipped checks helps to identify where the fees come from.
C. Skipped checks were written for more money than was available in the account.
D. A skipped check has not been cashed or deposited.

Answers

It hasnt been cashed or deposited. 

Answer:

D. A skipped check has not been cashed or deposited.

Step-by-step explanation:

We can say that a skipped check number means the check has not been cashed yet.

If we see the check book and there is a gap between the check numbers that you have written, then that means the missing number checks are not processes yet. The processing can be depositing or withdrawing/cashing.

So, the correct answer here is D. A skipped check has not been cashed or deposited.

What's the next three terms of the following sequence 160,136,112,88

Answers

Every number gets subtracted by 12. Therefore the next three numbers after 88 are 88-24, which is 64, then 64 - 24, which is 40, and 40-24, which is 16.
the next three terms are 64, 40, and 16.
On each number from the sequence you are subtracting 24 from it. So 160-24= 136 then 136-24= 112 then 112-24 = 88 then 88-24 = 64 and so on

if a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin (a+b)

Answers

The sine of the sum of two angles a and b, with sin a = 4/9 and sin b = 2/5, is calculated using the sine addition formula and is approximately 32.24/45.

To find sin(a+b) when given sin a = 4/9 and sin b = 2/5, we use the sine addition formula:

sin(a+b) = sin(a)cos(b) + cos(a)sin(b)

Since we have the sine values, but not the cosine values, we need to find cos(a) and cos(b). Knowing that [tex]sin^2(\theta) + cos^2(\theta) = 1[/tex]for any angle theta, we can find the cosines:

For cos(a): [tex]cos^2(a) = 1 - sin^2(a) = 1 - (4/9)^2 = 1 - 16/81 = 65/81[/tex]. So, [tex]cos(a) = \sqrt{(65/81)} = 8/9[/tex] (since a is in the first quadrant where cosine is positive).For cos(b): [tex]cos^2(b) = 1 - sin^2(b) = 1 - (2/5)^2 = 1 - 4/25 = 21/25[/tex]. So, cos(b) = [tex]\sqrt{(21/25)}= 4.6/5[/tex] (since b is in the first quadrant where cosine is positive).

Now, we plug these values into the formula:

sin(a+b) = (4/9)(4.6/5) + (8/9)(2/5) = 16.24/45 + 16/45 = 32.24/45

Thus, the sine of the sum of the two angles a and b is approximately 32.24/45.

A plant has a height of 8 1/4 inches what is the height of the plant after it grows 1 7/8 inches?

Answers

Final answer:

The height of the plant after it grows 1 7/8 inches is 81/8 inches.

Explanation:

To find the height of the plant after it grows 1 7/8 inches, we need to add 1 7/8 to the current height of 8 1/4. First, we can convert 8 1/4 to an improper fraction by multiplying the whole number (8) by the denominator (4) and then adding the numerator (1). This gives us 33/4 inches. Next, we can add 1 7/8 by finding a common denominator (8) and adding the numerators (1+7=8). So, 1 7/8 is equivalent to 15/8. Adding 33/4 and 15/8, we first need to find a common denominator which is 8. Multiplying the numerator and denominator of 33/4 by 2 gives us 66/8. Now, we can add 66/8 and 15/8 to get a total of 81/8 inches. Therefore, the height of the plant after it grows 1 7/8 inches is 81/8 inches.

Final answer:

After adding the growth of 1 7/8 inches to the original plant height of 8 1/4 inches, the new height of the plant is calculated to be 10 1/8 inches.

Explanation:

To calculate the new height of the plant after it grows an additional 1 7/8 inches, we simply need to add this growth to the plant's original height of 8 1/4 inches. The sum of these two measurements will give us the plant's total height.

Begin by converting the mixed numbers to improper fractions to make addition easier: 8 1/4 inches becomes 33/4 inches and 1 7/8 inches becomes 15/8 inches. Next, find a common denominator and add the two fractions.

Common denominator for 4 and 8 is 8.Convert 33/4 to an equivalent fraction with a denominator of 8, which is 66/8.Add 66/8 inches and 15/8 inches.(66/8) + (15/8) = 81/8 inches.

Now, convert the improper fraction back to a mixed number to determine the plant's new height:

81 divided by 8 is 10 with a remainder of 1.So, 81/8 inches is equal to 10 1/8 inches.

Therefore, after growing an additional 1 7/8 inches, the plant's new height is 10 1/8 inches.

what is the area of a circular mirror with a radius of 10 cm?

Answers

area=pi r squared
area=3.14 x 10squared 
area= 314
the answer is 314

Final answer:

The area of a circular mirror with a radius of 10 cm is calculated using the formula πr², which results in an area of 314.16 cm².

Explanation:

The area of a circular mirror can be calculated using the formula πr², where π (pi) is approximately 3.1416 and r is the radius of the circle. Given the radius of the circular mirror as 10 cm, we can substitute this value into the formula to find the area.

Area = π × (10 cm)²
A = 3.1416 × 100 cm²
A = 314.16 cm²

Therefore, the area of the circular mirror is 314.16 cm².

Answers

this is an arithmetic sequence with the common difference being 1

and if u have 1 cent on day 1 and 2 cents on day 2....then on day 40, u would have 40 cents....but we need the sum of all the days..

the sum of an arithmetic sequence can be found using the formula :
sn = n(a1 + an) / 2
n = number of terms = 40
a1 = first term = 1
an = last term = 40

now we sub
s(40) = 40(1 + 40) / 2
s(40) = 40(41)/2
s(40) = 1640/2
s(40) = 820.....820 cents = $ 8.20 <== the sum

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation to covert degrees fahrenheit to degrees celsius is given as,

(C × 9/5) + 32 = F

where C represents temperature in degrees Celcius and F represents the temperature in degrees Fahrenheit.

Now, we need to represent the degree Celcius by x, while the degree Fahrenheit by y. Therefore, the above equation can be rewritten as,

y = (x × 9/5) + 32

y = (9/5)x + 32

Hence, an equation that represents degrees Fahrenheit in terms of degrees celsius is y=(9/5)x+32.
