Answer:

x= - 2

Step-by-step explanation:

hello :

note : the equation of the axis symmetry  for the parabola : y =ax²+bx+c

when :  a≠ 0 is : x=- b/2a

in this exercice : a=1  and b=10

so : x= -10/2 = -5

PLEASE HELP. IF U GET THIS RIGHT I WILL MARK U BRAINLIEST!!! THANK U GUYS
KatRina [158]

Answer:

2

Step-by-step explanation:

The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer.  I'm sorry if my explaining isn't the best... I hope this helps though!!

What is the measure of the smallest interior angle of the hexagon shown?
yan [13]
<h3>Answer:  C) 70 degrees</h3>

=========================================================

Explanation:

We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees

Lets add up the angles, set the sum equal to 720 and solve for x

x+2x+115+2x+115+2x = 720

7x+230 = 720

7x = 720-230

7x = 490

x = 490/7

x = 70

This makes angle 2x = 2*70 = 140 degrees

We see that x = 70 is the smallest angle, so that's why C is the answer.

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.
Firdavs [7]

Answer:

New can holds 112.25\,\,cm^3 more than the old can

Step-by-step explanation:

Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is 339.12\,\,cm^3

Dimensions of the can are increased by a multiple of 1.10

To find: Difference between the volume of new can and volume of old can

Solution:

Volume of can (v) = 339.12\,\,cm^3

Let r, h denote radius and height of the can.

Let R, H denotes radius and height of the new can.

r = diameter/2 = \frac{6}{2}=3\,\,cm

h = 12 cm

R = 3(1.1)=3.3.\,\,cm

H = 12(1.1)=13.2\,\,cm

New volume (V) = \pi (R)^2H=\pi(3.3)^2(13.2)=451.37\,\,cm^3

So,

V-v=451.37-339.12=112.25\,\,cm^3
