??? Im lost in this question, could you be more specific?
(1.2×10^2) + (3.04×10^5)
They must be to the same power to add
3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2
1.2 * 10^2 + 3040 *10^2=
add the numbers keep the exponents the same
3041.2 * 10^2
there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent
3.0412 * 10 ^ (2+3)
3.0412 * 10^5
Answer:
y = 
x + 6 or y = x - 0.375
Step-by-step explanation:
For 2 lines to be perpendicular, their slopes must be <u>negative reciprocals</u>. In order to find the perpendicular of y - 4x - 6 = 0:
SLOPE INTERCEPT FORM: y = 4x + 6
SLOPE OF LINE A: m=4
SLOPE OF LINE B (the one you are looking for): m=
Since I don't know if you meant that they intercept on the x or y axis I will do both.
<u>y-axis</u>
y-6=(x-0)
y = x+6
<u>x-axis</u>
y-0=(x-1.5)
y=x-0.375
Answer:
First one: 114
Second one: 64
Step-by-step explanation:
For the first one, you can break apart the shapes to a square and a rectangle
The square is 7 x 7 (12 - 5 = 7)
The rectangle is 13 x 5
The square is 49
The rectangle is 65
Add them together
The first one is 114
For the second one you can break it apart to a triangle and a rectangle
The rectangle is 4 x 12
The triangle is 0.5 * 8 * 4 [8 is 12 - 4 (base)]
The rectangle is 48
The triangle is 16
Add them together
48 + 16 = 64
The second one is 64
The value of x is 21.
To find this one, we need to know the formula with intersecting lines outside of the circle.
It is that if you subtract the smaller arc from the larger arc and divide by 2, you will have the exterior angle.
Therefore, we can write and solve the following equation:
(5x - 63) / 2 =x
5x - 63 = 2x
3x = 63
x = 21
