b. Segment CB is a hypotenuse.
c. Segment CA is shorter than segment BA.
d. Angle C is congruent to itself.
Which of the following must be given to prove that - 1

Answers

Answer 1
Answer:

Answer:

The correct answer is option A.

Step-by-step explanation:

For the given triangles to be similar the segment AD must be an altitude of ΔABC.

We can provide a theorem for the same:

If we draw an altitude from the right angle of any right triangle, then the two triangles formed are similar to the original triangle.

Also all the three triangles are similar to each other.

Like here, in the triangle ABC, we draw an altitude from A to the side BC, thus forming 2 triangles; ΔDBA and ΔDAC. These both will be similar to ΔABC.

So, by the theorem it is proven that  ΔABC is similar to ΔDBA.

Therefore, option A is correct.

Answer 2
Answer: this answer is a (A) segment AD is an altitude at angle ABC

Suppose that the US plans to send a shipment of "rovers" to Mars. These are mobile robots, programmed to collect rock and soil samples, and then return to the landing site. The rovers operate independently of each other. The mean weight a rover is programmed to collect is 50 pounds, and the standard deviation of weights is 5 pounds. Weights collected by rovers are approximately normally distributed. If the US sends 10 rovers, what is the probability that the average weight of rock and soil brought back by these rovers will be between 48 pounds and 52 pounds? What sampling distribution should we use to compute this probability?

Answer:

B

Step-by-step explanation:

The other statements incorrectly describe the transformations.  C is facing a different direction and so without involving rotations it can not be the reflection of any of the other triangles.

For the equation y = 2x2 - 5x + 18, choose the correct
application of the quadratic formula.

Answers

Answer:

Option (2)

Step-by-step explanation:

For a quadratic equation,

ax² + bx + c = 0

roots of this equation can be determined by using quadratic formula,

x = (-b\pm√(b^2-4ac))/(2a)

Comparing this quadratic equation with the given equation,

y = 2x² - 5x + 18 = 0

a = 2

b = (-5)

c = 18

By substituting these values in the given formula,

x = (5\pm√((-5)^2-4(2)(18)) )/(2(2))

Therefore, Option (2) will be the answer.

Susan started with a certain number of dollars. She then decided on a number of dollars she would save each day. She added the dollars she saved to the amount with which she started. At the end of day 2, Susan had a total of 20 dollars saved. At the end of day 5, she had a total of 32 dollars saved. How many dollars does Susan start with? Show or explain your work.
Write an equation to model the number of dollars Susan has saved, y, after x days.

Answers

Answer:

Susan start with 12 dollars

Equation to model the number of dollars Susan has saved, y, after x days :4x-y+12=0

Step-by-step explanation:

Given :  She added the dollars she saved to the amount with which she started. At the end of day 2, Susan had a total of 20 dollars saved. At the end of day 5, she had a total of 32 dollars saved.

To Find: How many dollars does Susan start with? Show or explain your work.  Write an equation to model the number of dollars Susan has saved, y, after x days.

Solution :

Since At the end of day 2, Susan had a total of 20 dollars saved.

(x_(1) ,y_(1))=(2,20)

At the end of day 5, she had a total of 32 dollars saved.

(x_(2) ,y_(2))=(5,32)

So, using two point slope from find the equation of line

x denotes days

y denotes dollars she saved

y-y_(1) =(y_(2) - y_(1))/(x_(2)- x_(1))*(x-x_(1))

y-20 =(32-20)/(5-2)*(x-2)

y-20 =(12)/(3)*(x-2)

y-20 =4(x-2)

y-20 =4x-8

4x-y+12=0 --a

Thus the equation to model the number of dollars Susan has saved, y, after x days :4x-y+12=0

Now to calculate How many dollars does Susan start with?

Put x = 0 in equation a

4*0-y+12=0

y=12

So,Susan start with 12 dollars
