Answer:

y=2/3x-1

Step-by-step explanation:

slope intercept form is y=mx+b

where m is the slope and b is the y-intercept

You already know that the slope is 2/3 and the intercept is -1 so all you have to do is plug it in

y=2/3x-1

Find the unknown side of the triangle below <br><br> A. 4cm<br> B. 3cm<br> C. 9cm<br> D. 19cm
IRINA_888 [86]

Answer:

C - 9 cm

Step-by-step explanation:

We can use the Pythagorean theorem to figure out the missing side length, in this case, X.

The Pythagorean theorem states: a^2 + b^2 = c^2, with c being the hypotenuse. We have the side length of the hypotenuse which is 15, and we have another side length of 12. Let's put these back in our equation:

a^2 + 12^2 = 15^2;

If we simplify the squares by simply doing them: a^2 + 144 = 225;

Now let's subtract 144 from both sides to isolate the variable, a:

a^2 = 81;

Now we square both sides to find a:

a = 9

The missing side length is 9 cm.

the population of a local species of dragonfly can be found using an infinite geometric series where a1=30 and the common ratio
diamong [38]
The sum of any geometric sequence (if it converges, r^2<1) is of the form:

s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=number of terms...

s(n)=30(1-0.4^n)/(0.6)

s(n)=50(1-0.4^n)

Since r<1 the sum of the infinite series is just:

s=50

What is the approximate solution to the equation 3^t=29 ? a) 0.3263 b)3.0650 c) 3.3672 d) 9.6667
Vinvika [58]

Answer:

b

Step-by-step explanation:

using the law of logarithms

• log x^{n} = nlogx

given 3^{t} = 29 ( take log of both sides, that is base 10 )

log 3^{t} = log 29, hence

tlog 3 = log29 (divide both sides by log 3 )

t = \frac{log29}{log3} ≈ 3.0650 → b

The sequence here start out by adding 3 then 5 then 7
we see an increse of 2 to what we are adding so to get the next one we would add 2 to 7 to get 9 then add that to 22 to get 31
