For the answer to the question above, first find out the gradient.
<span>m = rise/run </span>
<span>=(y2-y1)/(x2-x1) </span>
<span>the x's and y's are the points given: "After three hours, the velocity of the car is 53 km/h. After six hours, the velocity of the car is 62 km/h" </span>
<span>(x1,y1) = (3,53) </span>
<span>(x2,y2) = (6,62) </span>
<span>sub values back into the equation </span>
<span>m = (62-53)/(6-3) </span>
<span>m = 9/3 </span>
<span>m = 3 </span>
<span>now we use a point-slope form to find the the standard form </span>
<span>y-y1 = m(x-x1) </span>
<span>where x1 and y1 are any set of point given </span>
<span>y-53 = 3(x-3) </span>
<span>y-53 = 3x - 9 </span>
<span>y = 3x - 9 + 53 </span>
<span>y = 3x + 44 </span>
<span>y is the velocity of the car, x is the time.
</span>I hope this helps.
F I’m not sure if I’m right but I think the answer is F
Answer:
i think it's a or c hope it helps :)
Explanation:
u don't have to give brainliest tho it's fine save ur points :)
<u>Answer:</u>
Mass in kg = 39.88
Mass in pounds = 87.92
<u>Explanation:</u>
We have the expression for Density, ρ = Mass / Volume, in this case density is given and we need to find mass and volume.
Volume of a sphere, we have the expression 
, where r is the radius of sphere.
Radius of sphere, r = Half of diameter = 15/2 = 7.5 cm
So 
Mass = Volume * Density = 1767.15*22.57 = 39884.49 g
Mass in kg = 39884.49/1000 = 39.88 kg
Mass in pounds = 39.88*2.205 = 87.92 lb
Answer:
b is called the power of base 10.
Explanation:
In the scientific notation form
the exponent b is called the power of the base 10.
