Answer:
None of the above.
Step-by-step explanation:
f(x) = [x], in the graphing calculator, is f(x) = int(x).
This means we take the floor of x, or round down all the time.
The question is asking us to find the limit as <em>x</em> approaches 2 from the right. Since the graph from [2, 3) is going to be y = 2, we know that if we are approaching from the right of x → 2, we will approach y = 2 (shown in graph).
If we were to approach x → 2 from the left, then we would approach y = 1 (shown in graph).
If we were to approach from both the left and the right, then we would get DNE.
Answer:
2/10 & 3/15
Step-by-step explanation:
1/5 = (1×2)/(5×2) = 2/10
1/5 = (1×3)/(5×3) = 3/15
You can form many more equivalent forms
Answer:
6
Step-by-step explanation:
maximum calories in a day = 540
no. of calories from the dog food = 320 x 1
= 480
∴ she can have: 540 - 480
= 60 calories to stay inside calorie range
no. of new treats she can have = 60 ÷ 10
= 6
Hope this helps!
Answer:
14. B 9, Isosceles
15. Corresponding angles; alternate interior angles; verticle angles
Step-by-step explanation:
Question 14 explanation -
Because two of the triangle's angles are congruent, this triangle classifies as an Isosceles Triangle. Therefore, we know that sides AB and AC must be congruent. This makes it easy to solve for x...just set both side lengths equal to each other and solve.
mAB = mAC
16 = x + 7
16 - 7 = x + 7 - 7
9 = x
x = 9
Given:
θ = 60°
Opposite side of θ = 6
Adjacent side of θ = x
Hypotenuse = y
To find:
The value of x and y.
Solution:
Using basic trigonometric ratio formula:
The value of tan 60° = √3
Multiply by x on both sides.
Divide by √3 on both sides, we get
Using Pythagoras theorem:
Taking square root on both sides, we get
Therefore, the exact values of x and y are .
