On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$

Which polynomial represents (6 x 2 −x−9)(4x−7)?

nydimaria [60]

Answer:

The answer to your question is 24x³ - 46x²- 28x + 63

Step-by-step explanation:

Data

(6x² - x - 9)(4x - 7)

Process

1.- Multiply 4x by the three terms of the first polynomial

(6x² - x - 9)(4x) = 24x³ - 4x² - 36x

2.- Multiply -7 by the three terms of the first polynomial

(6x² - x - 9)(-7) = -42x² + 7x + 63

3.- Add both result

24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63

Through point (0, 10) and PERPENDICULAR to the line through (-2, -9) and (-4, -17)?

inn [45]

Compute the slope of the line through (-2, -9) and (-4, -17):

$\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4$

Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes

$y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}$
