HELP ASAP!! (picture above)

To calculate minimum value, do -b/2a to get the x-value, and plug it in to get the y-value: 

-6/8 = -3/4

4 *  (-\frac{3}{4} )^{2} + 6 (-\frac{3}{4} ) - 18 =  \frac{9}{4} -  \frac{9}{2} - 18 =  - \frac{81}{4}

So the minimum value of g(x) is -81/4

This shows that g(x) has a lesser minimum value than f(x)

Find x. (Use pic for more info)
V125BC [204]

Answer:

x=75

Step-by-step explanation:

Hey There!

If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle

So essentially what I'm saying is that

2x-5=70+x

step 1 add 5 to each side

-5+5 cancels out

70+5=75

now we have

2x=70+x

step 2 subtract x from each side

x-x cancels out

2x-x=x

we're left with

x=75

20% of the rose Annette picked from a rose garden were red if she picked 10 red roses how many roses did she pick from the garde
horrorfan [7]

Answer:

Option A

Annette picked  50 roses  from the garden

Step-by-step explanation:

Let us understand the problem, designating letters to represent unknown quantities.

Let the total number of roses = x

20% of the roses were red means that 20% of x = red

Since the number of red roses = 10,

we will have that 20% of x = 10

mathematically, we will have

\frac{20}{100} \times x = 10\\x= \frac{1000}{20}= 50

hence, Annette picked  50 roses  from the garden

The US standard can is 4.83 inches high, 2.13 inches in diameter at the lid, and 2.60 inches in diameter at the widest point of
rewona [7]
The first thing we must do for this case is to calculate the volume of the can using the largest diameter:
 V = pi * ((d / 2) ^ 2) * (h)
 Where,
 h: height
 d: diameter.
 Calculating we have:
 V = pi * ((2.60 / 2) ^ 2) * (4.83) = 25.64 in ^ 3
 Then, to determine the amount of liquid in millimeters, we can use a simple rule of three:
 1 in ^ 3 ---> 16.3891 milliliters
 25.64 in ^ 3 ---> x
 Clearing x we have:
 x = ((25.64) / (1)) * (16.3891) = 420.22 mm
 answer
 The amount of liquid that has been bottled in milliliters is 420.22 mm
