So a times 10^n where 1≤|a|<10 and n is an integer is what i learned
so
a.
234=
2.34 times 100=
2.34 times 10²
b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵
c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵
d. ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
<span>A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, - + 4i, 4.2 - 12i, and - - i are all complex numbers. a is called the real part of the complex number and bi is called the imaginary part of the complex number.</span>
Answer:
(a)|MA|, |MB| and |MC|
(b) |BD|
(c) |BC|
Step-by-step explanation:
An adapted diagram of this question is attached. You can vary the labelled letters as required.
<u>Definition</u>
- A <u>radius </u>is a line drawn from the center of a circle to its circumference.
- A <u>segment </u>is a line that connects two points.
- A <u>diameter</u> is a chord which passes through the center of the circle.
- A <u>chord</u> is any line joining two points on the circles' circumference.
By these definitions:
(a)Segments that are radii of this circle.
We have: |MA|, |MB| and |MC|
(b)Segment that is a diameter of this circle.
|BD|
(c)A chord of this circle that is not a diameter.
|BC|
Answer:
The enlargement will be 25 times and the enlargement area will be .
Step-by-step explanation:
It is given that each grid unit is equal to 3 inches. SO we have to use this scale.
The total height of the scale drawing is 21 inch and the enlargement has a height given as 105 inches. Therefore it has scale factor of 5. It means that each dimension is enlarged by 5 times the dimension in the scale drawing. So the enlargement of the logo will be 25 times and the enlargement area will be 2250 square inches.
Try this option:
1. rule: P(E)+P(not E)=1.
2. according to the rule above
P(not E)=1-P(E)=1-0.3=0.7;
P(E)=1-P(not E)=(100-65)%=35%.
