Answer:

d = 0.7*t

Step-by-step explanation:

Given data,

Time Distance

10 7

15 10.5

20 14

From analysis,

1) d1/t1 = 7/10 = 0.7

2) d2/t2 = 15/20 = 0.7

3) d3/t3 = 14/20 = 0.7

It can be analysed from the figure that, at every point d/t = 0.7

Therefore, the relationship between t and d is

d = 0.7*t

t = d/0.7

8n = -3m + 1; n = -2, 2, 4

bogdanovich [222]

I am assuming you want to solve for m in each case

8n = -3m + 1

8(-2) = -3m + 1

-16 = -3m + 1

-3m = -17

m = $\frac{17}{3}$

8(2) = -3m + 1

16 = -3m + 1

-3m = 15

m = -5

8(4) = -3m + 1

32 = -3m + 1

-3m = 31

m = $\frac{31}{3}$

Given the graph of log y=log(2)x. Find the area of the three inscribed rectangles

evablogger [386]

Answer: $6+2log_{2} 6$

Step-by-step explanation:

$S=s_{1} +s_{2} +s_{3} = 2(h_{1} +h_{2} +h_{3} )$

$h_{1} = log_{2}2=1$

$h_{2} = log_{2}4=2$

$h_{3} = log_{2}6$

$S = 2(1+2+log_{2}6) = 6+2log_{2}6$

What is the value of y in this triangle?

yarga [219]

Answer:

26 degrees.

Step-by-step explanation:

The angles of triangles will always add up to 180 degrees.

The first angle is 50 degrees.

The second angle, is shown with a 76 degree angle next to it.

Since this is a 180 degree line, we can find the angle of the bottom right corner by doing 180 - 76. 180 - 76 is 104.

104 + 50 = 154 degrees.

The remaining 26 degrees is the answer to the value of y.
