Answer:

the vertex is (1,-1)

Step-by-step explanation:

y = −3x^2 + 6x − 4

the vertex is at

h= -b/2a where ax^2 +bx+c

h= -6/2(-3)

h= -6/-6

h=1

substitute this in to find the y value

y = -3(1)^2 +6(1)-4

y = -3+6-4

y = -1

the vertex is (1,-1)

Leroy borrowed P1500 at an annual simple interest rate of 12%. He paid P270 in interest. For what time period did Leroy borrow t

victus00 [196]

Answer:

C. 18 months

Step-by-step explanation:

Given data

Principal= P1500

rate= 12%

Simple interest= P270

We know that

Simple interest= PRT/100

substitute

270= 1500*12*T/100

cross multiply we have

270*100= 1500*12*T

27000= 18000 T

divide both sides by 18000

T= 27000/18000

T=1.5 years

That is 12 months + 6 months

in all = 18 months

The time is C. 18 months

HELP!!! THIS IS DUE TODAY! I WILL MARK BRAINLIEST

balandron [24]

Answer:

With replacement

$probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement =$ $\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}$

Without replacement

$probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}$

$probability \ of \ spade \ then \ red\ card\ without\ replacement = \frac{1}{4} \times\frac{4}{17} =\frac{1}{17}$

Quick! Will give brainliest!

Answer:

1 gallon and 1 pint

Step-by-step explanation:

I guess that the actual amount of water needed per player is 1/8 of gallon and not 18 gallons.

You will need to bring 9 x 1/8 = 9/8 = 1 ¹/₈ gallons or 1 gallon and 1 pint

1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces

1 gallon = 3.785 liters

The US is one of the few countries (along with Liberia, and Myanmar) that still uses the imperial system to measure things, e.g. inches, feet, yards, pounds, miles, pints, gallons, etc. The rest of the world uses the metric system, e.g. meters, liters, kilograms, etc.
