Multiply the triangles then divide to find the missing number
Answer:
Hi there!
The answer to this question is (B) 4
Step-by-step explanation:
Using the order of operations, you first solve what it is inside of the parenthesis, which in this case is (4-2), that equals to 2.
then you need to figure out what multiply by 2 gets 8. Out of all the answer choice (B) fits perfectly.
"In Grade 2 and early in Grade 3, students learned to use bar models to solve two-step problems involving addition and subtraction. This is extended in this chapter to include multiplication and division.
<span>Both multiplication and division are based on the concept of equal groups, or the part-part-whole concept, where each equal group is one part of the whole. In Grade 2, students showed this with one long bar (the whole) divided up into equal-sized parts, or units. This unitary bar model represents situations such as basket of apples being grouped equally into bags." </span>https://www.sophia.org/tutorials/math-in-focus-chapter-9-bar-modeling-with-multipli
Alright, lets get started.
We have given angle A = 40°
We are also given angle B is complement of A.
Complementary angles are two angles whose sum is 90, it means
angle B = 
angle B = 
angle B = 50° Answer
Now given, angle C is supplement of angle B.
Supplementary angles are two angles whose sum is 180°.
Means angle C = 
angle C = 
angle C = 130° : Answer
Means angle B = 50° and angle C = 130°
Hope it will help :)
The limit is x---->4-
The negative show that x approaches from the left
Now
As x approaches 4 from the left ... Means This number should be less than 4 (<4) but really close to 4.
Let's pick a Number
Say 3.99
Substitute this... You have
3.99/3.99-4
3.99/-0.01
If we choose x to be 3.999
we will have
3.999/-0.001
Notice the pattern... As x approaches 4 from the left... This limit will approach NEGATIVE INFINITY
Why?
As you approach 4 from the left... 3.9,3.99,3.999... You notice that the denominator becomes negative and EXTREMELY SMALL... and when you divide by an extremely small Number..... You'll get a relatively HUGE VALUE(You can try this... Use a calc... Divide any number of choice by a very small number... say.. 0.0000001.... You'll get a huge result
In our case... The denominator is negative... So it Will Approach a very Huge Negative Number
Hence
Answer.. X WILL APPROACH NEGATIVE INFINITY.
Vertical asymptotes are the zeroes of the denominator of a function
The denom. is x-4
Equate to zero to get the asymptote
x-4=0
x=4
Hence... There will be a vertical asymptote at x=4.
Have a great day!
