Factor as a product of two binomials x2-x-72

Mathematics

Answer:

(x - 9)(x + 8)

Step-by-step explanation:

Given

x² - x - 72

Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)

the factors are - 9 and + 8, since

- 9 × 8 = - 72 and - 9 + 8 = - 1, thus

x² - x - 72 = (x - 9)(x + 8)

Plot the image of point C under a dilation about the origin (0,0) with a scale factor of 1/2

yuradex [85]

Answer:

See Attachment for graph

Step-by-step explanation:

Given

Point C

Required

Plot C when dilated by 1/2

First, we have to determine the coordinates of point C

From the attached graph;

$C = (0,6)$

Next, is to determine the new point when dilated;

This is calculated as thus;

$New\ Point = Old\ Point * Scale\ Factor$

$C' = (0,6) * \frac{1}{2}$

Expand the bracket

$C' = (0 * \frac{1}{2}, 6* \frac{1}{2})$

$C' = (0, \frac{6}{2})$

$C' = (0, 3)$

This implies that C' will be plotted at x =0 and y = 3

<em>(See attached for point C')</em>

A park has a 333 meter (\text{m})(m)left parenthesis, start text, m, end text, right parenthesis tall tether ball pole and a 6.8

netineya [11]

Answer:option B & D are correct

Step-by-step explanation:

Given options are

A B C D E

Tether ball pole shadow 1.35 1.8 3.75 0.6 2

Flagpole shadow 3.4 4.08 8.35 1.36 4.8

Ratio of corresponding height & shadows should be same

3 meter tall tether ball pole and a 6.8 tall flagpole

=> Ratio = 6.8/3 = 68/30 = 34/15

A - 3.4/1.35 = 340/135 ≠ 34/15( 306/135)

B - 4.08/1.8 = 408/180 = 34/15 = 34/15 ( Correct option)

C 8.35/3.75 = 835/375 = 167/75 ≠ 34/15( 170/75)

D 1.36/0.6 = 136/60 = 34/15 = 34/15 ( Correct option)

E 4.8/2 = 48/20 = 12/5 = 36/15 ≠ 34/15

option B & D are correct
