Answer:
The Sum of the areas of theses triangles is 169/3.
Step-by-step explanation:
Consider the provided information.
The hypotenuse of an isosceles right triangle is 13 inches.
Therefore,
Then the area of isosceles right triangle will be: 
Therefore the area is: 
It is given that sum of the area of these triangles if this process is continued infinitely.
We can find the sum of the area using infinite geometric series formula.
Substitute 
in above formula.
Hence, the Sum of the areas of theses triangles is 169/3.
Answer:
Step-by-step explanation:
B is correct: We Divide it (the coefficient b) by 2 and square the result.
Answer:
B) vertical stretch
Step-by-step explanation:
Given that the cost of manufacturing x refrigerators is given by the function 
.
Now it says that the cost doubles for the year 2011 owing to higher raw material prices. So that means cost function will change from f(x) to 2f(x).
Now we need to decide the type of transformation from f(x) to 2f(x).
Remember that when f(x) changes to a*f(x) where value of "a" is greater than 1 then it stretches the function vertically by factor of "a".
in 2f(x), we have a=2
So that means "B) vertical stretch" is the correct choice.
The mystery number is 16 because 16 - 6 = 10.
Answer:
Step-by-step explanation:
Since Quadrilateral ABCD ~ PQRS, therefore:
Let's find the value of x by using the ratio of two corresponding sides of both quadrilaterals. Let's use:
CD = 5
RS = 4.5
DA = 4
SP = x
Cross multiply
Divide both sides by 5
