Based on the multiplication property of equality, the statement that completes the proof is: C. CD = b(sin A) and CD = a(sin B).

<h3>What is the Multiplication Property of Equality?</h3>

The multiplication property of equality is given as, if a/b = y, then a = yb. Both sides of the equation is multiplied by the same value.

In step 5 where the multiplication property of equality is applied, we would have:

sin(A) = CD/b

Multiply both sides by b

sin(A) × b = CD/b × b

b(sin A) = CD

CD = b(sin A)

This same property is applied to sin B = CD/a to get CD = a(sin B).

Therefore, the missing statement is: C. CD = b(sin A) and CD = a(sin B).

Binomial Theorem, proof
IrinaVladis [17]

It follows from the definition of the binomial coefficient:

\dbinom nr=\dfrac{n!}{r!(n-r)!}

So we have

(n+1)\dbinom nr=(n+1)\dfrac{n!}{r!(n-r)!}=(r+1)\dfrac{(n+1)!}{(r+1)!(n-r)!}

That is, (n+1) gets absorbed into the numerator's factorial, and we introduct (r+1) into the denominator. Now, (n+1)-(r+1)=n-r, so we get

(n+1)\dbinom nr=(r+1)\dfrac{(n+1)!}{(r+1)!((n+1)-(r+1))!}=(r+1)\dbinom{n+1}{r+1}

as required.

The frist brand is 30% and the second on is 55% in order to obtain 30 gallons of mixture that contains 35% how many gallons of e
snow_tiger [21]

yeet


first brand quantity is x

2nd brand quantity is y


x+y=30

0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5

solve for x and y

multiply first equation  by -0.3

-0.3x-0.3y=-9

add to 2nd equation


0.3x-0.3y=-9

<u>0.3x+0.55y=10.5 +</u>

0x+0.25y=1.5


0.25y=1.5

divide both sides by 0.25

y=6

sub back

x+y=30

x+6=30

x=24


you need 24 gallons of the first brand and 6 gallons of the 2nd brand

According to the Fundamental Theorem of Algebra, how many roots exist for the polynomial function? f(x) = 8x7 – x5 + x3+6
mote1985 [20]
<span>

Since the above polynomial is of degree 7, 7 roots exist.

If the degree is odd and the polynomial coefficients are real, there will be at least one real root, since complex roots come in conjugates.

For the given problem, there is exactly one real root.  All the rest are complex.</span>
