Answer 1

Answer: okay so this is going to take some time and I'm doing them by the numbers on them, not in the order you put them on here

Question 1: flagpole
angles are 27, 90, and 63 and height is x and hrizontal distance is 12
sin27/12 = sin63/x
x = sin63 / (sin27/12)
x= approx. 23.6

Question 2: eagle and prey
angles are 75, 90, and 15 and horizontal distance is x and height is 300ft
sin15/300 = sin75/x
x = approx. 1,120 ft (c)

Question 3: difference in heights
smaller triangle angles = 51, 90 (those are the only ones you need to know) height is x and hypotenuse is 805
sin90/805 = sin51/x
x= 625.602
larger triangle angles = 54, 90 (again, the only ones you need to know) height is x and hypotenuse is 846
sin90/846 = sin54/x
x=684.428
take the difference = approx. 59 (a)

Question 4: angle of depression of plane
angles = 85, 90, and 5 and height is x and horizontal distance is 4629
sin85/4629 = sin5/x
x=approx. 405 (d)

last one!!!!!!!!

Question 5: shadow of a tree
angle of elevation is x (you also have a 90 degree angle) height is 10 yards and horizontal distance is 14 yards and hypotenuse is y
14^2 + 10^2 = y^2
y= approx. 17.205
sin90/17.205 = sinx/10
x = sin^-1(10(sin90/17.205))
x = approx. 36 (d)

hope this helped

A large pharmaceutical company is trying to determine whether a drug aptly named Recall-Pro can increase your short-term memory capacity. The company prepares a double-blind study as follows:Step 1: A randomly selected pool of individuals is brought to a clinic and is evaluated for any existing health conditions that may impair the results of this experiment. Step 2: The remaining individuals are split into two groups: a treatment group and a control group. Step 3: The control group receives a placebo, but neither the researcher nor the individuals know this. Step 4: The treatment group receives Recall-Pro, but neither the researcher nor the individuals know this. Which step is flawed in the double-blind study? Why? A.Step 1; health screening should not eliminate participants from the study B.Step 2; it does not specify whether the two groups are chosen randomly C.Step 3; the control group does not receive the placebo D.Step 4; members of the treatment group should know that they have received the medication

Patricia roller skates 0.50 kilometers, straight north to the library. Then she walks 0.25 kilometers to her friend's house, which is straight north of the library. What is Patricia's displacement?

Answers

The answer is 0.75 kilometers.

Displacement is the shortest distance between the initial and the final point. But, Patricia roller skates in the straight line, so her displacement is the distance between the initial and the final point:

0.50 km + 0.25 km = 0.75 km.

Therefore, Patricia's displacement is 0.75 kilometers.

The answer is: 0.75 km, north

Select the term that best describes the statement. If a polygon has six sides, then it is a hexagon. A. Conjunction
B. Disjunction
C. Negation
D. Conditional

Answers

Answer:

Statement is conditional.

Step-by-step explanation:

Given the statement

"If a polygon has six sides, then it is a hexagon"

Option A: Conjunction

A conjunction statement is a compound statement which is formed by joining two statements with connector AND.

Hence, not a conjunction statement

Option B: Disjunction

A disjunction statement is a compound statement which is formed by joining two statements with connector OR.

Hence, not a disjunction statement

Option C: Negation

Opposite of a given statement is negation of statement

Option D: Conditional

Conditional statement is an if-then statement

As given statement is if-then statement therefore called conditional statement.

Option D is correct

its actually conditional...
