Is the following relation a function? {(0.3, 0.6), (0.4, 0.8), (0.3, 0.7), (0.5, 0.5)}
Readme [11.4K]

Answer:

no

Step-by-step explanation:

To be a function, the x values must correspond to one and only one y value.

In the coordinates given, (0.3, 0.6) and (0.3, 0.7) have the same x- value.

That means that they cannot be a function.

Solve for b1 from the formula: A=1/2h(b1+b2)
Andrews [41]

Answer:

B1 = \frac{2A-(h*B2)}{h}

or

B1=\frac{2A}{h}  - B2

Step-by-step explanation:

FOIL

(1/2)h*B1+ (1/2)h*B2=A

subtract the B2 term

(1/2)h*B1 = A- (1/2)h*B2

multiply by 2

h*B1 = 2A - h*B2

divide by h

B1 = \frac{2A-(h*B2)}{h}

or

B1=\frac{2A}{h}  - B2

A swimming pool has to be drained for maintenance. The pool is shaped like a cylinder with a diameter of 5 m and a depth of 1.4
Korolek [52]

Answer:

8 hours

Step-by-step explanation:

basic equation

Q (flow rate) = V (volume)/ t (time)

so to find the time we just rearrange the equation and become

t = V/Q

V of cylinder

V = πr²T

and r (radius) = ½ diameter

V = 3.14 x 5² x 1.4

V = 109.9 m³

if the Q is 13 m³/hour then

t = 109.9/13 = 8.453 hours

round to nearest hour = 8 hours

Which pair of measurements is equivalent?
NNADVOKAT [17]
Let's look at each pair and change it so the first one in the pair will be what the second one will be converted to.
8,600 mg = 86,000 mg; So now, the first one is not equivalent.
2,500 g = 250,000 g; Not that one either.
3.4 kg = 3.4 kg; This one is correct. We can check by checking the last pair.
480 g = .0048 g; Nope.
So 3.4 kg, 3400 g would be the correct answer.
