The graph of h( x) = -x2 - 10x + 5 can be used to model the height in feet of a
curved support for an archway, where the x-axis represents the ground level and x
represents the distance in feet at the ground level from one side of an arch support
to the other. Find the height of the highest point of the archway.

0 is its x and y coordinate

i would say true? if the unit was informational and it "refreshed your understanding", then true.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
