1.95 * 10^7
Step-by-step explanation:
19.5 million
write in standard notation
19500000
convert to scientific notation (by making the number such that the largest digit is in the one's place)
1.95 * 10^7
Answer:
B (second table in list)
Step-by-step explanation:
The function is a quadratic with vertex and y-intercept at (0,-2). The parabola opens up meaning only y - values above -2 are a part of the function. Since range is the set of all y values, then the range is
.
The domain is not restricted and it is all real numbers.
The inverse of the function is where x and y are switched. So the range becomes the domain and vice verse.
This means the domain of the inverse is
and the range of the inverse is all real numbers.
A.) 3/4 are plain
b.) 75% are plain
c.) 18 are plain and 6 are sesame. 2 dozen bagels is the same as 24 bagels. Since there are 4 total parts, you have to divide the number of bagels into 4 equal parts [24 / 4]. Since each part is 6 bagels, multiply 6 by 3 since the ratio of plain to sesame is 3:1. Yours should get 18 plain bagels. Then, since 3 of the 4 parts are plain, and each part is 6 bagels, there are 6 sesame bagels.
Law of sines can be used to solve this problem:
(note - let x represent the missing side length.)
1. set up proportion.
sin 90°/25 = sin 55<span>°/x
2. solve.
(x) sin 90</span>° = (25) sin 55<span>°
(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
