The area of the triangle is 557. 7cm²

Area of a triangle

In order to determine the area of a triangle, we have to know the size of the base and the size of the height

The formula for finding the area of a triangle is given as = half the base multiplied by the height

In mathematical form, it is written as;

Area = 1/ 2 × base × height

From the figure given, we have their lengths to be'

base = 57. 2 m

height = 19. 5 m

Let's substitute the values

Area = 1/ 2 × 57. 2 × 19. 5

Area = 1/ 2 × 1115. 4

Find the ratio

Area = 557. 7 m²

The area of the triangle is 557. 7cm²

Hence, the area of the triangle is 557. 7cm²

Brittany and four of her friends want to join a softball league. The league requires teams to have at least nine players, but teams cannot have more than eighteen players. In interval notation, how many more people can join Brittany's team?

Answers

The additional number of people is [4, 13]

How to determine the number of people?

Brittany and four of her friends are five people.

So, we have:

n = 5

The conditions are given as

At least = 9At most = 18

Let the additional number of people be x

So, we have the following inequalities

x + 5 ≥ 9 and x + 5 ≤ 18

Subtract 5 from both sides

x ≥ 4 and x ≤ 13

Express as interval notation

[4, 13]

Hence, the additional number of people is [4, 13]

Using limits, it is found that the correct statement defining the sequence is:

The sequence converges to 1.

What is the rule that defines this sequence?

The numerator starts at 3 and increases by 1, while the denominator starts at 4 and increases by 1, hence the rule is:

[tex]\sum_{n = 0}^{\infty} \frac{3 + n}{4 + n}[/tex]

To verify if it converges, we find the limit as n goes to infinity, hence:

[tex]\lim_{n \rightarrow \infty} \frac{3 + n}{4 + n} = \lim_{n \rightarrow \infty} \frac{n}{n} = \lim_{n \rightarrow \infty} 1 = 1[/tex]

Faith is tracking the number of burpees she does at a constant rate. Last

78 burpees in 6 minutes. How many burpees did Faith do per minute last
week and this week?
Please help me I will mark u the brainliest

Answers

This is a unit rate question. We can solve this in chronological order of steps:

Step 1: Write out the beginning for the first unit rate.

Faith completed 60 burpees in 5 minutes last week.

Step 2: Since 60 burpees were completed in 5 minutes, we can divide 60 by 5 to find how many burpees were completed in 1 minute.

60 divided by 5 equals 12.
5 divided by 5 equals 1.

Our fraction for how many burpees Faith did in a minute last week is 12/1. This reduces to 12, meaning that Faith did 12 burpees last week.

Step 3: Find the unit rate for this week.

Faith completed 78 burpees in 6 minutes this week. Because of this, we can divide 78 by 6 to find how many burpees Faith completed this week.

78 divided by 6 equals 13.
6 divided by 6 equals 1.

Our final fraction for how many completed burpees Faith did this week is 13/1, which reduces to 13. Therefore, Faith completed 13 burpees per minute this week.

Your final answer: In terms of separate values, Faith completed 12 burpees per minute last week and 13 burpees per minute this week. If you need help, let me know and I will gladly assist you.

Answers

Answer:

See below

Step-by-step explanation:

y = -6x^2 + 24x-100

solve for 'x'

y + 100 =   -6x^2 + 24x   = -6(x^2-4x)    complete the square for x

(y+100) /(-6 ) =    (x-2)^2 -4                     add 4 to both sides

(y+100)/(-6) +4   = (x-2)^2                       sqrt both sides

sqrt [  ( y+100)/(-6) + 4  ]  + 2 = x           change  x and y

y = ± sqrt [ (x+100)/(-6) + 4 ] + 2            simplify (if needed)

The first step in the construction of a line perpendicular to line AB and passing through an external point m is:

a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB

What are the steps to construct a perpendicular line from an external point?

To construct a perpendicular line, a compass and a scale are used.

Consider a line AB and an external point M.

Step 1:

Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.

Step 2:

Name the two intersecting points on line AB as X and Y.

Draw the arcs from these two points to the opposite side of point M with the same compass width.

Step 3:

Name the intersecting point of two arcs as N.

Draw a line connecting the two points M and N using scale.

Step 4:

Using a protractor, measure the angle of the line MN with the line AB.

The angle must show 90°.

Thus, the line MN perpendicular to line AB and passing through an external point M is constructed.
