It is a cold, icy miserable day in Whitehorse. You find yourself driving along the highway on your way out of town. You are driving a little fast (80km/h) as you approach a very icy corner on the highway, the corner essentially is frictionless. Luckily the engineers realised tourists like you would drive too fast into this corner and designed the corner to be banked and allow cars to safely navigate the 80m radius turn. At what angle did the engineers bank the corner?

An engineering company is hired to improve the efficiency of a transmission line. In their report, they discuss ways that will allow them to reduce the current by a factor of four. Assuming this is done, by what factor will the power losses be reduced?

Use the following information to answer the next question.The Labrador Retriever’s coat colours are black, yellow, and chocolate.Yellow is produced by the presence of a recessive epistatic gene, which has the effect of masking the black and chocolate colour genes. Black (B) is dominant to chocolate (b). Therefore, the possible genotypes and corresponding phenotypes are:

Predict the percentage of offspring that would be black in colour for each of the following crosses. Record your answer as a whole number. 

Methanoic acid,HCOOH(aq) , is sometimes known as formic acid (from the Latin formica for ant, since ants secrete formic acid). Suppose that an ant uses 1.0 x 10-5 mL of formic acid with a pH of 2.456 every time it bites. What mass of methanoic acid does it use in each bite?

#1. Which of the following statements correctly describes the Law of Independent Assortment? Select one:a). Non-allelic genes do not affect each other if they are located on separate chromosomes.b). A large Punnett square can be used to predict the outcome of a parental cross involving two traits.c). The dominant allele is represented with an uppercase letter and the recessive allele is represented with a lowercase letter.d). Sometimes all alleles lack dominance, which leads to a blending of traits.

Which of the following statements correctly identifies the difference between plant and animal cells division? 

a.) Both plant and animal cells undergo mitosis and cytokinesis, but they lack the interpase 

b.) plant cells lack centrioles, and they form a cell plate during cytokinesis 

c.) Plant cells lack centomeres, and they form a cell to produce two daughter cells 

d.) The cell walls of the plant prevent the process of cytokinesis 

A rescue helicopter locates two people caught in an avalanche. The angle of elevation from the first perosn to the helicopter is 26.7 degrees, and the angle of the elevation from the second person to the helicopter is 48.9 degrees. IF the distance between the two people is 165m, determine how far both people are from the helicopter.

In ABC, c= 10cm, b= 8cm, and angle B= 35

b)Solve the triangles

Patricia and Trent are 48 m apart. The angle of elevation from Patricia to the hot air balloon hovering in the sky between her and the Trent is 43 degrees, while the angle of elevation from Trent to the balloon is 31 degrees. 

a.) Draw a diagram of the situation

b.) Determine the distance between the ballon and the person farthest from the balloon. Round to th nearest tenth of a metre
