3.25 x 2 = 6.5

2.50 x 1.5 = 3.75

3.75 + 6.5 = 10.25

Answer:

ask sombody else

Step-by-step explanation:

guess we dont

Step-by-step explanation:

an = A×n² + B×n + C

a1 = -5 = A×1² + B×1 + C = A + B + C

a2 = -4 = A×2² + B×2 + C = 4A + 2B + C

a3 = -1 = A×3² + B×3 + C = 9A + 3B + C

a2 - a1 = -4 - -5 = 1 = 4A+2B+C-A-B-C = 3A + B

3A = 1 - B

A = (1 - B)/3

a3 - a2 = -1 - -4 = 3 = 9A+3B+C-4A-2B-C = 5A + B

3 = 5A + B = 5(1 - B)/3 + B

9 = 5(1 - B) + 3B = 5 - 5B + 3B = 5 - 2B

4 = -2B

B = -4/2 = -2

A = (1 - -2)/3 = (1 + 2)/3 = 3 / 3 = 1

-5 = A+B+C = 1 - 2 + C = -1 + C

-4 = C

so,

an = n² - 2n - 4

The two roots are

[tex]\alpha = -8+3i,~~~ \beta = -8-3i\\\\\\x^2 - (\alpha + \beta)x + \alpha \beta = 0\\\\\implies x^2 - (-8+3i-8-3i)x + (-8+3i)(-8-3i)=0\\\\\implies x^2 +16x + (-8)^2+3^2 =0\\\\\implies x^2 +16x +64+9=0\\\\\implies x^2 +16x +73[/tex]

Hence the answer is D.

Answer:

CBA

Step-by-step explanation:

B is the middle n angles should be btn two lines ie AB and BC. so they had a common point B hence the joining occured at B

Answer:

Im pretty sure it's false because 7.4p could 74, 148, 222 or 296. so it would be the other way around. It's false.

Answer:

3¹⁶

Step-by-step explanation:

While adding numbers with exponents, if the base of the numbers is same, then it will also be the same in the final answer and the exponents add

Hope this helps!

Answer:

You can just add the exponents power

9+7=16

So its 3^16 in exponential form

You can think of it like this.

for 3^9 its

3*3*3*3*3*3*3*3*3

And for 3^7 its

3*3*3*3*3*3*3

Now your multiplying them all together.

Really your jsut adding the value so in the end

3*3*3*3*3*3*3*3*3*3*3*3*3*3*3*3

So its

3^16

Answer:

<2 = 28°

Step-by-step explanation:

3y+ 53 = 7y -55 (Corresponding angles)

collect like terms

-4y= -108

y= 27°

3y-53 = 28

<2 =28° (Alternating angles ; 2 parallel lines)

Step-by-step explanation:

xy=360

x-y=75

(x-y)^2+2xy=(x+y)^2-2xy hence we have for x+y= ((x-y)^2+4xy)^0.5 which somehow equals 84.1

Hmmm, maybe this?

Step-by-step explanation:

Answer:

314.16 cm squared

Step-by-step explanation:

Answer:

Use the distributive property to multiply 2 by x−1.

l2x-2I=11

2x-2=-11

Add 2 to both sides of the equation.

2x=-9

Divide both sides by 2.

x=13/2

That's the final answer

Hope u have a great day!!

Check the picture below.

F = sales for Friday

we know that the total of weekend sales for Germany was F + 317 + 405.

we also know that 405 is really 37.19% of that amount, say "x", which is the 100%, so

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 405&37.19\\ x&100 \end{array}\implies \cfrac{405}{x}=\cfrac{37.19}{100}\implies 40500=37.19x \\\\\\ \cfrac{40500}{37.19}=x\implies 1089~\approx ~ x \\\\[-0.35em] ~\dotfill\\\\ \stackrel{friday}{F} + \stackrel{sat/sun}{317} + \stackrel{monday}{405} \approx 1089\implies F +722 \approx 1089\implies \boxed{F\approx 367}[/tex]

This question is basically asking for the area of the tablecloth. Remember that A = l • w.

12 • 7 = 84

So, Henry will need to buy 84 ft^2 of fabric.

Answer: 19

Step-by-step explanation:

2 lines crossing create 2 pairs of equal angles. The opposite angles are the same. Same goes in a circle.

9514 1404 393

Answer:

  arc DC = 19°

Step-by-step explanation:

The acute central angles are vertical angles, so have the same measure. Vertical angles with the same measure intercept arcs with the same measure. The measure of the arc is the measure of the central angle it subtends.

Arc AB = Arc DC = 19°
