Answer:

m + 1/4 = 2/3

Step-by-step explanation:

2/3 - 1/4= 5/12; 1/4 + m = 2/3

We know it's subtraction as the tape diagram above has 2 pieces, both smaller than the whole tape diagram below it. Also, knowing it has 2 pieces and that 1/4 is small than 2/3 help us know that it's subtraction.

I hope I've helped!

Circle the equations that represent quadratic functions a. y=3x+1 b. y=x^2+3 c. y=x^3-3 d. x^2+3y=8

Elena L [17]

Answer:

$B. y=x^2+3 \\\\D.$ $x^2+3y=8$

Step-by-step explanation:

A quadratic function is a function in which the highest power of the unknown variable is 2.

Formally, a quadratic function is defined as a function of the form:

$f(x)=ax^2+bx+c, a\neq 0$

From the given options, only B and D has the highest power as 2. Therefore, the equations that represent quadratic functions are:

$B. y=x^2+3 \\\\D.$ $x^2+3y=8$

If cosθ =1/3 , then sinθ = _____.

DedPeter [7]

We are given: cos theta = 1/3. Thus, adj side = 1 and hyp = 3. Using the Pythagorean Theorem to find the length of the opposite side, represented by x.

1^2 + opp^2 = 3^2, or 1 + x^2 = 9, or x^2 = 8. Here, x could be either sqrt(8) or -sqrt(8): sqrt(8) if angle theta is in QI, and -sqrt(8) if in QIV.

Thus, the sine of angle theta could be either sqrt(8)/3 or -sqrt(8)/3.
