➷ a) (1)^2 + 20 = 21

(2)^2 + 20 = 24

(3)^2 + 20 = 29

b) (5)^2 + 20 = 45

(6)^2 + 20 = 56

There are 5 terms less than 50

Answer:

x = 15

Step-by-step explanation:

The easiest way to solve this is to realise that a triangle takes up half the area of a rectangle of the same width and height.

We are told that the width of the triangle is 10, and that the line of length 10 is perpendicular to the longest side of the triangle.  Because of that we know that x can be multiplied by ten to get the area of the rectangle that is twice the area of the triangle.

We are also told that the triangle's area is 75 units.  With all of that put together, we can say:

a = (10 * x) / 2\\75 = 5 * x\\x = 15

The function f(x) is given by the set of ordered pairs.
My name is Ann [436]
Answer: f(0) = 6.

Explanation:

Ther ordered pairs are: (x,y) or (x, f(x) )

So, (1,0) means that f(1) = 0 which denies the fourth choice.

(-10,2) means that f(-10) = 2 which denies the first choice

(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.

Find the seventh term of the sequence which has a first term of 1/2 and has a common ratio of three
prohojiy [21]

The seventh term of the sequence is 364.5

<h3>Geometric progression </h3>

From the question, we are to determine the seventh term of the sequence

Using the formula,

a_{n}  = ar^{n-1}

Where a_{n} is the nth term

a is the first term

and r is the common ratio

From the given information,

a = 1/2

r = 3

Thus,

a_{7}  = (\frac{1}{2}) 3^{7-1}

a_{7}  = (\frac{1}{2}) 3^{6}

a_{7}  = \frac{1}{2} \times  729

a_{7}  = 364\frac{1}{2} \ OR \ 364.5

Hence, the seventh term of the sequence is 364.5
