You have no exponential functions listed to choose from, but in this problem it is understood that the base of the log is 10 because it is not stated otherwise and a base of 10 is the "norm" for logs. So rewritten with that in mind, you have log base 10 (784)=a. In exponential form, that looks like this: 10^a=784. You could solve for a by typing in "log(784)" into your calculator to get that the exponent is equal to 2.894316063. If you raise 10 to that power you get 784.

Mark is in training for a bicycle race. He needs to ride 50 km a week as part of his training. He rode 18.23 km on Monday and 13

The answer is B-about 18km

This is because you round 18.23 to 18km

then you round 13.94 to 14km

you add these rounded numbers together

you take it away from 50km

the answer would then me 18km

but it be ABOUT because that was only a rough estimate because it was rounded

When we want to find the roots of a one-variable function, we look for where its graph intersects the x-axis. In this case, the graph intersects the x-axis at $x=1.$

The vertex of a parabola is the highest or lowest point on it, depending on whether the leading coefficient of the quadratic function is negative or positive. In this case, we see that the lowest point is $(1,0).$

For the y-intercept, just look for where the graph intersects the y-axis; in this case, that point is $(0,1).$

Using this information, the vertex-form equation of the parabola is $y=1\cdot(x-1)^2+0,$ so the factors are two copies of $x-1.$ In this case, the value of $a$ in the equation $y=a(x-h)^2+k$ was conveniently 1; if that's not the case, you'll want to plug in $x=0$ to solve for the value of a that gives the correct y-intercept.
