the overall length of a machine part consist of three pieces joined together. these pieces measure 2 3/4 in., 1 1/2 in. and 7/8

almond37 [142]

You just add them together. First, you give them all the same denominator. So 2 3/4 goes to 2 6/8 and 1 1/2 goes to 1 4/8. 1 4/8 + 2 6/8 + 7/8 = 3 17/8. 3 17/8 simplified = 5 1/8. So 5 1/8 inches

The equation of the quadratic function represented by the graph is y=a(x-3)^2-1. What is the value of a?

Y_Kistochka [10]

Answer:

Value of a is 2

Step-by-step explanation:

Given the equation of the quadratic function represented by the graph is $y=a(x-3)^2-1$ . we have to find the value of a.

As seen in the figure, parabola cuts the graph at point (2,1) implies point (2,1) is one of the solution of the given quadratic equation i.e of given parabola.

∴ Point (2,1) satisfies the given equation.

Hence, we can find the value of a by putting the value of x and y, we get

$1=a(2-3)^2-1$

⇒ $2=a$

Hence, the value of a is 2

tresset_1 [31]

Answer:

C. 3.33 hours

Step-by-step explanation:

Use the algebra work equation:

$\frac{1}{tb}$ = $\frac{1}{t1}$ + $\frac{1}{t2}$ , where tb is the time to work together, t1 is the time it takes one person, and t2 is the time it takes the other person
