Answer:
-9
Step-by-step explanation:
We are told in the question that:
Xavier climbs 9 feet up into an apple tree.
The direction symbol or sign for upwards movement = Positive (+) sign
If Xavier would climb back down , he will climb back down 9 feet as well
The direction symbol or sign for downwards movement = Negative (-) sign
Since we know the distance (or how far) he has to climb by downwards is also 9 feet, therefore, the integer that represents the direction and how far he will climb to get back down to the ground is -9
Answer:6x+126in^2
Step-by-step explanation:
a =15 long
b=x. Wide
A=ax
A=15x represenrs picture area
Add on each side of picture 3 in
a1=15+6=21 in
b1=x+6
Calculate area
A1=a1b1
A1=21(x+6)
Area of frame = A1-A
Area of frame=21(x+6)-15x=21x-15x+126=6x+126in^2
Answer:
hello :
note : secy = 1 / cosy
tany = siny /cosy
sin y+cos y+tan y sin y = sin y+cos y+( siny /cosy)sin y
= ( siny cosy + cos²y + sin²y) / cosy
= (siny cosy +1) / cosy......because : cos²y+sin²y =1
= (siny cosy) / cosy + 1 / cosy
= (siny/cosy) × cosy + 1/cosy
sin y+cos y+tan y sin y = tany cosy + secy
Answer:
There are two main types of correlation coefficients: Pearson's product moment correlation coefficient and Spearman's rank correlation coefficient. The correct usage of correlation coefficient type depends on the types of variables being studied. We will focus on these two correlation types; other types are based on these and are often used when multiple variables are being considered.
