Answer:
Step-by-step explanation:
One equivalent expression is 7^6: 7 is used as a multiplicand 7 times.
Another equivalent expression would be (7^2)(7^5). Note that 2 and 5 add up to 7.
25 plus 28 equals 53 and 512 times 53 is 27,136 so he will need 27,136 blocks for all of his students hope this helped
To get the vertex of the parabola we proceed as follows;
y=-7(x-4)^2-5
The above can be written as:
y=-7x^2+56x-117
The values of a,b and c are:
a=-7, b=56 and c=-117
x=-b/(2a)
x=-56/(-7*2)=4
but;
y=-7x^2+56x-117
y=-7(4)^2+56(4)-117
y=-5
Thus;
x=4 and y=-5
The vertex will be at point (4,-5)
Answer:
375
Step-by-step explanation:
