Answer:

Eddie used the incorrect ratio for sin

Step-by-step explanation:

sinT = $\frac{opposite}{hypotenuse}$ = $\frac{UV}{UT}$ = $\frac{8}{17}$ , then

∠ T = $sin^{-1}$ ( $\frac{8}{17}$ )

How many solutions does 3x^2+11x+10=0 have

r-ruslan [8.4K]

Answer:

Step-by-step explanation:

Let's find the discriminant $\Big(\sqrt{b^2-4ac}\Big)$

$\sqrt{11^2-4(3)(10)} = 1$

It is a positive number, therefore there are 2 solutions

Answer + Explanation + Theory

When a number is divided by a number it results in a quotient and a remainder

E.g. 9 / 4 = 2 remainder 1

9 is the dividend
4 is the divisor
2 is the quotient
1 is the remainder

Same way when a polynomial is divided by a linear expression

E.g.

Ax^2 + bx + c / (x-b) = (x+a) + r

Which can be rearranged to

ax^2 + bx + c = (x+a)(x-b) + r

When x = - a or b, only the remainder is left since either (x+a)(x-b) is 0.

If x = - a or b is substituted into the polynomial and the value is 0 then there is no remainder,

This would suggest (x+a) or (x-b) are factors of the polynomial.

Now apply this logic to these questions

1. Let’s assume (x-4) is a factor, this would mean that when x=4 is substituted into the polynomial the answer would be 0.

This is the case, therefore the remainder is 0.

2. Having seen the logic above (applied using the remainder and factor theorem) the linear expression is a factor of the polynomial.

The correct answer is Choice D: 68%.

You have to make a tree diagram with all of the possibilities.

Here are the possibilities:

Rain - Win = 0.6 x 0.8 = 0.48
Rain - Loss = 0.6 x 0.2 = 0.12

No Rain - Win = 0.4 x 0.5 = 0.2
No Rain - Loss = 0.4 x 0.5 = 0.2

Adding up the two winning options gives us 68%
0.48 + 0.2 = 0.68
