Answer:
≈ 66.5 m
Step-by-step explanation:
Using the sine ratio in the right triangle
sin12° = 
= 
( multiply both sides by 320 )
320 × sin12° = d , then
d ≈ 66.5 m ( to 1 dec. place )
Answer:
C
Step-by-step explanation:
To show triangles ABC and DEF congruent by putting them oneach other, you need the following transformations:
reflect triangle DEF across the x-axis
then move triangle DEF left 1 unit
finally move triangle DEF down 1 unit
the option that has all this is C
Answer:
cubic
Step-by-step explanation:
The degree of a term with one variable is the exponent of that variable. When there is no exponent, the degree is 1. When there is no variable, the degree is 0.
The degrees of the terms in this expression are, left to right, ...
2, 3, 1, 0
The largest of these numbers is the degree of the polynomial: 3.
A polynomial of degree 3 is called a cubic.
___
<em>Comment on degree names</em>
degree 1: linear
degree 2: quadratic
degree 3: cubic
degree 4: quartic
Y=mx + b
3x-4y=12
4y=3x-12
y=3/4x-3
when x = 0, y = -3
when y = 0, x = 4
Hope this helps.
