By using algebra and trigonometry properties, the expression (cot² t + 1) · (sin² t + 1) is equivalent to the expression cot² t + 2.

In this problem we find an equivalence between two trigonometric expressions. This can be done by transforming the expression at one side by using algebra and trigonometry properties until the expression of the other side is found. The procedure is now presented and explained:

(cot² t + 1) · (sin² t + 1)                              Given

(cot² t + 1) · sin² t + (cot² t + 1)                 Distributive property

cot² t · sin² t + sin² t + cot² t + 1              Distributive property

cos² t + sin² t + cot² t + 1                         cot t = cos t / sin t / Associative and commutative properties / Existence of multiplicative inverse / Modulative property

1 + cot² t + 1                                              cos² t + sin² t = 1

cot² t + 2                                                  Commutative and associative properties / Definition of addition

Thus, the expression (cot² t + 1) · (sin² t + 1) is equivalent to the expression cot² t + 2.

The greatest number of students that can attend the party is 16.

Given, the teacher has 48 juice boxes and

64 candies for a Halloween party.

Each student will be given an equal number of juice boxes or sweets, and each one must be consumed.

how many (greater) number of students can attend the party = ?

In order to determine the greatest students we need to calculate the greatest common divisor of the numbers.

To calculate the greatest common divisor, we need to find out the prime factors of each number.

Therefore, by the method of prime factorization.

Prime factors of 48 = 2 × 2 × 2 × 2 × 3

Prime factors of 64 = 2 × 2 × 2 × 2 × 2 × 2.

Now, HCF of (48,64) = 2 × 2 × 2 × 2 = 16

Therefore we get the gcd as 16.

Hence the greatest number of students who can attend the party is 16.

From the given information:

you have entered a 42-mile biathlon that consists of a run and a race. During your run, your average velocity is 5 miles per hour, and through your race, your average velocity is 27 miles per hour. You finish the race in 4 hours.

Then

Total distance of the race = 42 miles

The average velocity of the running = 5 miles per hour

The average velocity of the bicycling = 27 miles per hour

Then

If let he covers 27 miles with the cycles then

The distance he runs = 42-27

The distance he runs = 15.

Then it means he runs for a 3 hours.

The equation that is parallel and perpendicular are y + 4  = 7/5(x-35) and y+4 = -5/7(x - 35) respectively.

A line is defined as the shortest distance between two points. The formula for finding the equation of a line in point slope form is:

y - y₁ = m(x-x₁) (Parallel lines)

y - y₁ = -1/m(x-x₁) (Perpendicular lines)

Given the following parameters;

Point = (35, -4)

Given the equation 7x-5y = 0

5y = 7x

y = 7/5x

Slope = 7/5

Substitute the slope and point into the equation

y + 4  = 7/5(x-35) (Parallel lines)

y +4 = -1/(7/5)(x-35) (Perpendicular lines)

y+4 = -5/7(x - 35)(Perpendicular lines)

Answer:

No solution

Step-by-step explanation:

Step-by-step explanation:

the slope of a line is always the factor of x, and it is defined as ratio (y coordinate change / x coordinate change) when going from one point to another on the line.

in that sense it is y/x.

the perpendicular slope turns that ratio upside-down and flips the overall sign.

so, in our case, the original slope is 3 = 3/1.

the perpendicular slope is then -1/3.

so, now, we have the slope and a point, and we can start with the point-slope form of the line equation :

y - y1 = a(x - x1)

"a" being the slope, (x1, y1) being the point.

y - 1 = -1/3 × (x - 9) = -x/3 + 3

y = -x/3 + 4

and that is the usual slope-intercept form

y = ax + b

"a" is again the slope, "b" is the y-intercept (the y value when x = 0).

Answer:

Brahmagupta in 628

Step-by-step explanation:

Answer:

Zero and its operation are first defined by Brahmagupta in 628. He developed a symbol for zero: a dot underneath numbers.

An equation and number line which shows that a number and its opposite are additive inverses is: 2 + (-2) = 0 in graph B.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values that are placed at equal intervals along its length.

An additive inverse can be defined as a number (n) which when added to another number (a) makes it equal to zero (0). This ultimately implies that, an additive inverse is the opposite of another number (a).

Mathematically, an additive inverse can be represented by the following expressions:

a + n = 0

a = -n

In this context, we can reasonably infer and logically deduce that an equation and number line which shows that a number and its opposite are additive inverses is 2 + (-2) = 0 in graph B (see attachment).

Answer: Rate of tree's height per year = 0.275 m per year.

Rate of tree's trunk per year = 0.025 m per year.

Step-by-step explanation:

Given data,

Exactly 120 years​ ago, students planted a tree in front of their school

Since​ then, the tree has grown 33 meters taller

The distance around the trunk has increased by 3 meters.

Define Unit rate :

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

So, we can write,

There are 2 various unit rates in this:

The increase of the tree's height per year

The increase of the tree's trunk per year

Let us assume,

The increase of the tree's height per year = x

The increase of the tree's trunk per year = y

we can solve it :

Rate of tree's height per year x = 33m / 120 years

                                                x = 0.275 m per year.

Rate of tree's trunk per year y = 3m / 120 years

                                              y = 0.025 m per year.

Therefore,

Rate of tree's height per year = 0.275 m per year.

Rate of tree's trunk per year = 0.025 m per year.

The probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384

Probability is the extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases.

Now it is given that,

The proportion of free throws the player makes, p = 80% = 0.8

The number of throws, n = 3

The throws the player makes, r = 2

Since the probability is given as,

P(r) = nCr x p^r x (1 - p)^(n-r)

So, the probability that an NBA player makes 2 of his next 3 free throws

Putting the values we get,

P(2) = ³C₂ x (0.8)^2 x (1 - 0.8)^(3-2)

Solving we get,

P(2) = 3 x 0.64 x (0.2)^(1)

Thus we get,

P(2) = 3 x 0.64 x 0.2

Multiplying we get,

P(2) = 0.384

this is the required probability that an NBA player makes 2 of his next 3 free throws.

Thus, the probability that an NBA player who makes 80% of his free throws makes 2 of his next 3 free throws is 0.384
