1. SOH CAH TOA tells you the tangent is the ratio of the Opposite side to the Adjacent side, that is, 4/3. (This correct answer is not among your choices.)

2. The mnemonic SOH CAH TOA can be helpful here. It tells you

... Sin = Opposite/Hypotenuse

... Cos = Adjacent/Hypotenuse

... Tan = Opposite/Adjacent

\dfrac{c}{b}=\tan{C}\\\\ \dfrac{b}{a}=\sin{B}\\\\ \dfrac{b}{c}=\tan{B}\\\\ \dfrac{c}{a}=\cos{B}

3. Reference the ratios listed above (for the second problem). You see that sin(α) = cos(90°-α). That is, the sine of an angle is the cosine of its complement and vice versa. The appropriate choice is

... D. 19/20

If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​
Elza [17]

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.

Teagan is dividing 6 by 11. If she continues the process, what will keep repeating in the quotient?
USPshnik [31]

Answer:

54 will keep repeating in the quotient.

Step-by-step explanation:

Quotient is defined as the answer we get after dividing a number by another number. For instance 10 / 2 = 5. Here 10 is dividend, 2 is the divisor and 5 is the quotient.

In this case 6 divide by 11 will give 0.54545454545....

54 keep repeating in the quotient.
