Answer:

Step-by-step explanation:

Calculate the lengths of JK and JL using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = J(2, 1) and (x₂, y₂ ) = K(- 4, 2)

JK = [tex]\sqrt{(-4-2)^2+(2-1)^2}[/tex]

= [tex]\sqrt{(-6)^2+1^2}[/tex]

= [tex]\sqrt{36+1}[/tex]

= [tex]\sqrt{37}[/tex] ≈ 6.1 units

Repeat with (x₁, y₁ ) = J(2, 1) and (x₂, y₂ ) = L(7, 4)

JL = [tex]\sqrt{(7-2)^2+(4-1)^2}[/tex]

= [tex]\sqrt{5^2+3^2}[/tex]

= [tex]\sqrt{25+9}[/tex]

= [tex]\sqrt{34}[/tex] ≈ 5.8 units

Thus JK is longer than JL → A

find the measure of angle 6

Answers

Answer:

∠6 = 125°

Step-by-step explanation:

__________________________________________________________

FACTS TO KNOW :-

When any 2 lines intersect each other at any point , the vertical angles are always equal to each other .

__________________________________________________________

According to the figure ,

∠6 is present vertically opposite to the angle whose measure is 125°.

∴ Hence ∠6 = 125°.

125 trust me lol btw yw it’s like 5am and i stayed up all night

At 7:00 am, the temperature was -4℉. At 9:00 am, it was 8° warmer. What was the temperature at 9:00 am? *

Answers

4℉.

What we know about Degrees is that there is a Positive type and a negative type.

(i.e: 30℉ is positive and -30℉ is negative.)

If the temperature was -4℉ at 7AM, then it is negative. If it goes up by an amount that is more than 4 then that negative will go up to a positive temperature. In this case: At 9AM it was 8° warmer.

Warmer is a keyword. If it is warmer by an amount, Negative temperatures will go up to a positive and positive temperature will just go up. If it gets cooler, negative temperatures will go down further and positive temperatures will go down to a negative.

So lets work out this problem with our newfound knowledge.

-4° F at 7AM

8° warmer at 9AM

-4 + 8 = 4.

The temperature was 4° at 9AM.

A local bakery sells cupcakes for $3.50 each. The fixed monthly cost totals $275 which includes rent, utilities, and wages. Each cupcake costs the bakery 0.90 to make.

Answers

Answer: 110 cupcakes

Step-by-step explanation:

Assuming this question is asking for the breakeven point, you can find that by using the formula:

= Fixed cost / Contribution margin

Contribution margin = Sales price - variable cost (amount to make one cupcake)

= 3.50 - 0.90

= $2.60

Breakeven point = 275 / 2.60

= 109.77

= 110 cupcakes

Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula.
a1 = - 4, r = 6

Answers

Answer:

331776

Step-by-step explanation:

The formula for geometric

sequence is given below

ar^n-1

Where a= first term, r= common ratio

From the question, a1 = - 4, r = 6 , n= 5

Then if we substitute, we have

ar^n-1

5th term= ar^n-1

= (-4×6)^(5-1)

=-24 ^ 4

=331776

Hence, the first five terms is =331776

The formula is 5th term= ar^(5-1)
