Tom travels along the M1 from Leicester to London which is a distance

Gemiola [76]

Tom did not break the 70mph speed limit of M1.

To know if Tom breaks the <em>speed limit </em>of the M1, we must first calculate Tom's speed and compare it to M1's speed limit.

Using the formula below,

s = d/t............... Equation 1

Where:

s = Tom's speed
d = distance from Leicester to London
t = time taken to travel from Leicester to London

From the question,

Given:

d = 143 miles
t = 8:25 to 10:15 = 2 hours 10 munites = (2+10/60) = (2+0.17)
t = 2.17 hours.

Substitute these values into equation 1

s = 143/2.17
s = 65.899 mph.

Hence, Since Tom's speed is less than the M1 speed limit, Tom did not break the 70mph speed limit of M1.

Answer:

The power is 32 because that is what 2 to th 5 is , 2 is the base as its the number being multiplied 5 times which leaves 2 as the exponent.

Given cos theta = - 2/5 and sin theta < 0, find the six trigonometric values. I need help with this

Lena [83]

Answer:

$\sin\,\theta =-\frac{\sqrt{21} }{5}$

$\tan\,\theta =\frac{\sqrt{21} }{2}$

$\sec\,\theta = \frac{-5}{2}$

$cosec\,\theta =\frac{-5}{\sqrt{21} }$

$\cot\,\theta =\frac{2}{\sqrt{21} }$

Step-by-step explanation:

$\cos\theta =\frac{-2}{5}$

As both $sin\,\theta$ ,

$\theta$ lies in the third quadrant.

In the third quadrant,

$\sin\theta$

$\sin\,\theta =-\sqrt{1-\cos^2\,\theta} \\=-\sqrt{1-(\frac{-2}{5})^2 } \\\\=-\sqrt{1-\frac{4}{25} }\\\\=-\sqrt{\frac{25-4}{25} }\\\\=-\frac{\sqrt{21} }{5}$

$\tan\,\theta = \frac{\sin\,\theta}{\cos\,\theta }\\\\=\frac{\frac{-\sqrt{21} }{5} }{\frac{-2}{5} }\\\\=\frac{\sqrt{21} }{2}$

$\sec\,\theta =\frac{1}{\cos\,\theta }\\\\=\frac{1}{\frac{-2}{5} }\\\\=\frac{-5}{2}$

$\ cosec \,\theta = \frac{1}{sin\,\theta }\\\\=\frac{1}{\frac{-\sqrt{21} }{5} }\\\\=\frac{-5}{\sqrt{21} }$

$\cot\,\theta =\frac{1}{\tan\,\theta}\\\\=\frac{1}{\frac{\sqrt{21} }{2} }\\\\=\frac{2}{\sqrt{21} }$

Can I have help with this please?

mamaluj [8]

Answer:

x+1+2x-6= 16

3x-5 =16

3x=16+5

3x=21

x=21/3

x= 7

VW= 2x-6 = 2(7) -6 = 14-6 = 8

Determine the slope-intercept form of the equation of the line parallel to y = x + 11 that passes through the point (–6, 2).

MArishka [77]

Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8
