Multiple answer
for each of the following questions check the box for each of the answers that apply.
determine which of the following expressions are equivalent to the expression
below. (choose three answers)
d.1
54 kilometers per hour
step-by-step explanation:
according to rules:
1 km = 1000 meter
which means that 1 meter = 1/1000 km
1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]
which means that 1 second = 1/3600 hour
therefore, 1 kilometer/hour =
thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.
15 meter/second= which is the required answer.
well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
step-by-step explanation:
the correct option is:
b. a value of the variable that makes the polynomial equal to zero.
why?the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).
for example, given the following polynomial:
the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:
therefore, we have that the root of the polynomial is equal to 2.
we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.
hence the correct option is:
b. a value of the variable that makes the polynomial equal to zero.
have a nice day!
