I agree that and means multiplication, but in this problem it says OR. When you have or, you have to add. 1/2 +1/6 would be 2/3

Graph the line with the equation y = x + 6.

Tcecarenko [31]

Answer:

Hi there!

Your answer is:

Based off the equation we know that the slope is 1 and the y intercept is 6. We know that slope is rise/run so it goes UP one unit for every unit it goes RIGHT! We must start at the point (0,6) because that is the y intercept

V1 = 70 mL; P1 = ? kPa; P2 = 105 kPa; V2 = 15 mL *

algol [13]

Answer:

490kpa

Step-by-step explanation:

V1 = 70ml and P1 = ? kpa

V2 = 15ml and P2 = 105kpa

if 15ml will give me 105kpa

then how many times is 70ml greater than 15ml

70/15 = 4.6667

then multiply it by 105kpa

4.6667 * 105 = 490kpa

meaning that if 15ml will give me 105kpa

then 70ml which is (15*4.667) will give 490kpa

Assume that u⋅v=4, ‖u‖=5, and ‖v‖=3. What is the value of 4u⋅(4u−7v)?

shutvik [7]

Step-by-step explanation:

It is given that,

$u{\cdot}v=4\\\\|u|=5\\\\|v|=3$

We need to find the value of $4u{\cdot} (4u-7v)$

Firstly, we should simplify $4u{\cdot} (4u-7v)$

$4u{\cdot} (4u-7v)=4u{\cdot} 4u-4u{\cdot} 7v$

Now using distributive property : x(y-z)=xy-yz

So,

$4u{\cdot} (4u-7v)=4u{\cdot} 4u-4u{\cdot} 7v\\\\=16u{\cdot}u-28{u{\cdot} v}\\\\=16|u|^2-28(u{\cdot}v)\\\\=16\times 5^2-28\times 4\\\\=288$

So, the value of $4u{\cdot} (4u-7v)$ is 288.
