Mathematics
1 answer:
denis-greek [22]2 years ago
7 0
<h3>Explanation:</h3>

y = (x - 1)(x + 3)

Find y intercept:

y = (0 - 1)(0 + 3)     ⇒       y = -3

coordinates: (0, -3)

Find x intercept:

(x - 1)(x + 3) = 0        ⇒     x = 1, x = -3

coordinates of x intercept: (1, 0), (-3, 0)

Vertex: x = -b/2a = -2/2(1) = -1

y = (-1 -1)(-1 +3) = -4

coordinates: (-1, -4)

On a scale drawing with a scale of 1 cm: 3 m , the height of a tree is 5 cm. How tall is the actual tree?
Neko [114]
In 3 metres there are 300 centimetres. Each centimetre on the scale is 300 centimeters, or a ratio of 1:300. The tree is 5 centimetres on the scale. Each centimeter on the scale is 300 centimetres, therefore 5 centimetres on the scale is 1500 centimetres. 1500 centimetres is equal to 15 metres.

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 4, 14, 16, 4, 20, 19, 12
marysya [2.9K]
The mean is simply the average of the total movies seen so..
\frac{4 + 14 + 16 + 4 + 20 + 19 + 12 + 10}{2} = mean
\frac{99}{2} = mean
49.5 = mean

the median is the middle number (or the average of the middle 2 numbers)
so if we line up the numbers in order and cross them out from both ends we get 12 & 14 so we take the average of the 2
13 = median
