Step-by-step explanation:

When the car stops, the speed is zero.

When S = 0, -10t + 45 = 0, t = 4.5.

Hence it will take 4.5 seconds for the car to stop.

Answer:

209.5 grams are protein

Step-by-step explanation:

Protein is 25 % or .25

We have 838 grams of peanut butter

25% of it is protein.  Multiply the grams by the percent that is protein to determine how many grams are protein

grams protein = total grams times percent protein

                         =838*.25

PLEASE HELP ASAP!!! (ii only)

The equation of the tangent line can be found using slope formula and fact that slope = dy/dx.

\frac{dy}{dx} = \frac{y - y_0}{x - x_0}

where (x0,y0) is point A ---> (0,-1)

Then rearrange equation into slope-intercept form:
y = \frac{dy}{dx}(x - 0) -1

Finally sub in x=0 into dy/dx to get slope at the point (0,-1)

y = 3x -1

Plsss help it’s due today in an hour!!! (test grade)
Rudik [331]

Answer:

the area is 50.24 cm^{2}.

Step-by-step explanation:

The formula to find area of a circle is A=πr^{2}. A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24 cm^{2}. Hope this helped! :]
