Answer:
1.5 meters
Step-by-step explanation:
.75 *2 = 1.5, therefore 1.5 meters.
A.
Step-by-step explanation:
Range of a function is the value that we get when a function is solved.
Say, f(x) = y.
We say this "set of x is domain" whereas "set of y is range".
Suppose,
set A = {1,2} & set B = {1,2,3} & f(x) = y
Let,
f(1) = 1, & f(2) = 2.
What we get is that there is no x for 3.
We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.
Answer:
560 sandwiches were made
Step-by-step explanation:
set up a porportion.
45/252=55/x
45x=13860
x=308 cheese sandwichs
308+252=560
Answer:
A) ERROR
B) ∠C = 26°
Step-by-step explanation:
Houston, We have a problem!!! too much information
If we had a legit triangle, the law of sines would hold
19/sin138 = 8/sin20
28.395 = 23.390
as this is NOT an equality, the triangle does not exist as described.
IF it did, we'd get different results depending on which set we used
∠F = 180 - 138 - 20 = 22°
Law of sines
19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>
or
8/sin20 = DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>
If we attempt to use Law of cosines
DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>
so really none is correct because we attempt to use trig calculations to a non-triangle.
12) AC² = 15² + 19² - 2(15)(19)cos120
AC = 29.51270...
29.51270 / sin120 = 15/sinC
C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>
