suppose abc is a right triangle with sides a, b, and c and right angle at c. use the pythagorean theorem to find the unknown side length. then find the values of the six trigonometric functions for angle b. rationalize the denominators when applicable.
The unknown length is 28. the values of the six trigonometric functions for angle b that is tan B = 7/24
From the question,
we are given
a = 96 and c = 100, to get the unknown side 'b',
we will substitute the given values into the formula above;
c² = a²+b²
100² = 96² +b²
b² = 100² - 96²
b² = 10,000 - 9216b²
= 784b = √784b = 28
Hence, the unknown length is 28.
To get tanB, we will use the SOH, CAH, TOA trigonometry identity.
According to TOA,
tan B = opposite/adjacenttan B = b/a (note that side b is the opposite in this case since the angle we are considering is B)
Given, b = 28 and a = 96tan B = 28/96tan B = 4*7/4*24
tan B = 7/24

On 1st January 2017, Samantha and Dyfan invested money into different
savings accounts.
They did not make any further payments into their accounts or withdraw any
money from their accounts.
Dyfan invested £3000 in a savings account that paid interest at a rate of
1.02% every 3 months.
Interest is paid on the last day of each 3-month period.
Calculate the date when Dyfan will first have over £3600 in his account.

The number of years when Dylan would have over £3,600 in his account is 18 June, 2021.
When would Dylan have over £3,600?The time that If the account earns interest every 3 months, it means that the value increases quarterly or 4 times a year. The account would increase at an exponential rate. This means that both the amount invested and the interest that has already been earned would increase in value 4 times a year.
The formula that can be used to determine the time is:
Time = In(FV / PV) / r
Where:
FV = future value
PV = present value
r = interest rate
t = In (£3,600 / £3,000) / 0.0102
t = In 1.2 / 0.0102 = 17.87 / 4 = 4.468 years
4 years = 2017 + 4 = 2021
0.468 x 12 = 5.616 months
January + 5 months = June
0.616 x 31 = 19 days

The line segment NO of the triangle MNO, that is similar to the triangle QRS, has a length of 25 meters.
How to determine the missing length of geometric system formed by two similar triangles
In this problem we have a system of two similar triangles. Two triangles are proportional when the sides of a triangle are proportional to the corresponding sides of the other triangle. Herein we find the following relationship:
MN / QR = NO / RS = MO / QS
If we know that QR = 1 m, MN = 5 m and RS = 5 m, then the length of the line segment NO is:
NO = (MN / QR) · RS
NO = (5 m / 1 m) · 5 m
NO = 25 m
The line segment NO has a length of 25 meters.

#2 The number of bacteria in a refrigerated food is given by N(T)=20T2-20T+120 for -2T14 Tand where T is the temperature of the food in Celsius.
(a)Explain the meaning of -2T14 in this context
(b)Determine the temperature the number of bacteria will be minimal?
(c)Find number of bacteria in a above
(d) Sketch a graph
From the given quadratic function, it is found that:
a) The interval -2 ≤ T ≤ 14 gives the range of the temperature of the food in Celsius.
b) The number of bacteria will be minimal for a temperature of 0.5 ºC.
c) The minimum number of bacteria is of 115.
d) The graph that models the situation is sketched at the end of the answer.
What does the quadratic function models in this problem?The quadratic function is given as follows:
N(T) = 20T² - 20T + 120, -2 ≤ T ≤ 14.
In which:
T is the temperature in Celsius of the food.N(T) is the number of bacteria in the food.The function has a domain of -2 ≤ T ≤ 14, meaning that these are the possible temperatures of the food.
For a concave up quadratic function, the minimum value happens when the input is of:
Tm = -b/2a.
For this problem, the coefficients of the quadratic function are as follows:
b = -20, a = 20.
Hence the temperature in which the number of bacteria will be minimal is of:
Tm = 20/40 = 0.5 ºC.
The number of bacteria with this temperature is given by the numeric value of the function when T = 0.5, that is, each instance of T in the function is replaced by 0.5, hence:
N(0.5) = 20(0.5)² - 20(0.5) + 120 = 115 bacteria.
