Step-by-step explanation:
The rule of law of the square root of constants is taking the nearest divisible number which has a square root of an integer. since 25 taken to the power of 0.5 is equal to 5 or -5, the rule already applies. In this case, 2 multiplied to 5 is equal to choice E. 10.
Hi there!
The line is in slope-intercept form. This is y=mx+b, where b is the y intercept. Thus, because it is in this form, we can see that the y intercept is 3.
Now, for the x intercept. The x intercept is at y=0. Thus, we can just set y equal to 0 and solve for x.
0=-7x+3
-3=-7x
x=3/7
Thus, the x intercept is 3/7.
Our two answers are - x intercept = 3/7, y intercept = 3
Hope this helps!
The correct question is
Use calculator to find √(<span>68.1) to the nearest hundredth
we know that
T</span><span>o the nearest 'hundredth' is the same as saying </span>
<span>'Round off to two decimal places
</span><span>To do this you first have to determine the answer with a calculator to at least 3 decimal place
</span>√68.1-------> 8.252
The rounding will happen at the 5. It will either stay 5 or round up to 6, depending on the next digit which is a 2.
<span>The 2 is below 5, so the answer rounds down to give 8.25
</span>
the answer is
8.25
1/2 b-39=101
+39 +39
1/2 b= 140
2(1/2) b= 140(2)
b=280
