Mathematics

klemol [59]3 years ago

Answer:

(61x + 3) = 125 \degree

(25x + 5) =55 \degree

Step-by-step explanation:

The first angle us (61x+3)

The second angle is (25x+5)

We use corresponding angles to get the top angle as a linear pair to (25x+5).

We use sum of angles on a straight line to obtain:

(61x + 3) + (25x + 5) =180 \degree

Group similar terms

61x + 25x = 180 - 3 - 5

86x = 172

x = 2

We substitute to get:

(61x + 3) = 61 \times 2 + 3 = 125 \degree

(25x + 5) =25 \times 2 + 5 = 55 \degree

Answer:

53 52 72 61 68 58 47 47 (arrange it)

47 47 52 53 58 61 68 71 (done!)

Mode: 47 (appear twice)

Median: (53+58)/2 = 55.5

Mean = 47+47+52+53+58+61+68+71/ 8

=457/8

=57.12

The length of a rectangular plot of land is 10 yards more than its width. If the area of the land 600 square yards , find the di
vagabundo [1.1K]
<span>Let the width of the rectangular plot of land be 'x' yards. Given that the length of the rectangular plot of land is 10 yards more than its width. So, width of the rectangular plot of land = (x + 10) yards. Also given that the area of the rectangular plot of land is 600 square yards. We know that, area of a rectangle = length * width That is, (x+10) * x = 600 x^2 + 10x = 600 x^2 + 10x - 600 = 0 x^2 + 30x - 20x -600 = 0 x(x + 30) - 20(x + 30) = 0 (x +30)(x -20) =0 Therefore, either (x + 30) = 0 or (x - 20) = 0 If x + 30 = 0, then x = -30 and If x - 20 = 0, then x = 20 Since 'x' represents the width of a rectangular plot of land it cannot be negative. Therefore, width of the rectangular plot of land = 20 yards length of the rectangular plot of land= x + 10 = 30 yards</span>

F(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x =  2, f(x) = f(2) = - 18 (component of y of the vertex)
