Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
The discount would be $77.5 as 310 divided by .25 is 77.5.
Answer:
$135
Step-by-step explanation:
You need to divide:
675/5= 135
135 equals 1/5 of 675
Hope this helps! :)
Area of a triangle = 1/2 x base x height
Area = 3.75 sq m
Base = 2.5 m
3.75 = 1/2 x 2.5 x height
3.75 x 2 = 2.5 x height
7.5/ 2.5 = height
height = 3 m
Answer:
The value of n would be 5
Step-by-step explanation:
This is understanding how to take numbers and writing them in scientific notation.
125,000 = 1.25 x 10⁵
First of all.
125,000 = 125,000.0 (See that decimal point?)
We want that decimal point behind the number 1 as seen in the scientific notation. All you have to do is move that decimal point to the left until you reach the ones place.
125000. → 1.25
(You're not finished yet)
Since we moved the decimal five times, then we must put an exponential value of 5 above the 10
In conclusion:
125,000 = 1.25 x 10⁵
