Answer:
Step-by-step explanation:
To solve this problem is multiply 2 by 2 and then 2 which gives you 8.
Then you will add 2+2+2 and get six. For when multiply exponents you are adding.
Answer:
40
Step-by-step explanation:
Developing an initial ratio of the number of giant swallowtails to the total number of observed butterflies, you can then use this ratio to form a proportion (equivalent ratios) to solve for the amount of giant swallowtails expected out of 480:
Since 32 + 56 + 8 = 96, then the original ratio is 8/96. To find the expected number out of 480:
, where 'x' is the number of giant swallowtails
Cross-multiply: 96x = (8)(480) or 96x = 3840
Divide: 96x/96 = 3840/96
Solve: x = 40
Answer:
1) not a right triangle
2) not a right triangle
3) Right triangle
4) Right triangle
Step-by-step explanation:
To determine if side lengths could be a right triangle
The formula is a^2 + b^2 = c^2
a=is the smallest number
b= the middle sized number
c= the largest number
1) 12,15,20
144+225= 400
Doesn't work so no
2)10,11,15
100+121= 225
Doesn't work so no
3)5,12,13
25+ 144 = 169
works so yes
4) 16,30,34
256 + 900 = 1,156
Works so yes!
Answer:
Step-by-step explanation:
Reciprocal trig functions are opposite or mirror of the normal trig functions. The normal trig functions are as follows:
Sine = opposite side/hypotenuse
Cosine = adjacent side/hypotenuse
Tangent = opposite side/adjacent side
The reciprocals of the above trig ratios would be
Cosecant = hypotenuse/opposite side
Secant = hypotenuse/adjacent side
Cotangent = adjacent side/opposite side
Therefore, looking at the given options, the trigonometric function that can be described as a reciprocal trig function is
