butalik [34]3 years ago
3 0

Answer:

tan²A  

Step-by-step explanation:

1+tan²A/1+cot²A      Simplify 1+tan²A first

sec²A/1+cot²A         Now simplify 1+cot²A

sec²A/csc²A            Simplify sec²A and csc²A    

\frac{1}{cosA}/\frac{1}{sinA}                   Simplify the fraction

sin²A/cos²A = tan²A

Graph the line that passes through the points (4,-6) and (-4,-8) and determine the equation of the line.
allochka39001 [22]

Answer:

y=1/4x-7; can't put graph on here

Step-by-step explanation:

m=y2-y1/x2-x1

m=-8+6/-4-4=-2/-8=1/4

put it in point-slope form with (4,-6) as the base

y-y1=m(x-x1)

y+6=1/4(x-4)

y+6=1/4x-1

y=1/4x-7

What are the coefficients in the polynomial 7x^2 -4x+6
alisha [4.7K]
7 and -4

Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).

If 8 cakes cost $62.40, how much would 3 cakes cost?
Ilya [14]

Answer:

<h2><em><u>$23.40 </u></em></h2>

Step-by-step explanation:

<em><u>Given,</u></em>

Cost price of 8 cakes = $62.40

<em><u>So,</u></em>

Cost price of 1 cake = $ \frac{62.40}{8}

<em><u>Therefore,</u></em>

Cost price of 3 cakes

= $(\frac{62.40}{8} × 3)

  • <em>[On dividing 62.40 by 8]</em>

= $(7.80 × 3)

  • <em>[On multiplying]</em>

= $23.40

<em><u>Hence,</u></em>

<em><u>The required cost of 3 cakes is $23.40 (Ans)</u></em>

A circle with area 3/2pi and central angle of 60 degrees. What is the area of the circle
Anika [276]

Answer:

28.28(simplified from 28.2743338834)

Step-by-step explanation:

area of sector= (center angle/360)*area of circle

we are already given the area of sector as 3/2pi

so

3/2pi=(60/360)*x

(x is area of circle)

3/2pi=4.71238898038

4.71238898038=1/6x

divide both sides by "1/6"

28.2743338834=x

hope this helps!

Distributive property of <br>4x 567​
Maksim231197 [3]

567 = 500+60+7

4*567 = 4*(500+60*7)

4*567 = 4*500 + 4*60 + 4*7 ... see note below

4*567 = 2000 + 240 + 28

4*567 = 2268

--------

note: multiply the outer term 4 by each term inside the parenthesis to use the distributive property. The general distributive property is a*(b+c) = a*b+a*c. This can be extended to a*(b+c+d) = a*b+a*c+a*d. You can have as many terms as you like inside the parenthesis.
