Answer:

$y=7.5x+2.5$

Step-by-step explanation:

$y=7.5x+b$

$(40)=7.5(5)+b$

$40=37.5+b$

$b=40-37.5$

$b=2.5$

the linear equation in slope-intercept form is $y=7.5x+2.5$

∠U=90°, TS = 73, SU = 55, and UT = 48.

ololo11 [35]

Answer:

sin S = is the ratio found.

Step-by-step explanation:

It is given that m∠U = 90°

TS is the hypotenuse = 73 units

UT is the adjacent side of the right angle = 48 units

SU is the base of the triangle = 55 units

Now we have to find the ratio as,

sin S =

Plugin the values, we will get,

sin S =

So the ratio was found.

Tim estimates that 60÷5.7 is about 10.Will the actual quotient be greater than 10 explain

Zepler [3.9K]

Well first you can do the problem. So take 60 divided by 5.7. When it is done it will come out to about 10.5263 which is a irrational number. So yes the quotient will be larger than 10.
Hope I helped!

The eight term of a geometric progression is given by Sn= -[-3(sin^2x + cos^2x)^n + In e. Find the first term and common ratio.

igor_vitrenko [27]

Answer:

Step-by-step explanation:

Sn= -[-3(sin^2x + cos^2x)^n + In e.

sin^2x + cos^2x = 1 and ln e = 1, so

Sn = -(-3)^n + 1

When n = 8

this = -(-3)^8 + 1

jolli1 [7]

<h3>given;</h3>

5,870,000,000,000 miles.

The distance light travels in 100 years.

<h3>solution:</h3>

The distance of the light travels in 100 years is:

5,870,000,000,000 × 100 miles.

= 587,000,000,000,000 miles

= 587 × 10^12 miles.
