Mathematics
1 answer:
Dafna1 [17]3 years ago
5 0

Answer:

option C is correct answer ..

Step-by-step explanation:

angle A + angle B + angle C = 180° ( by angle sum property of triangle )

3x + 4x-19+ 3x -1 = 180

10x + -20 = 180

10x = 180 +20 = 200

x = 200/10 = 20 °

angle A = 3× 20 = 60 °

angle B = 4× 20 - 1 9 = 61 °

angle C = 3× 20 -1 = 59 °

angle B is greatest so side opposite to it will be greatest in length ....so length of AC is greatest ....

so option C is the correct answer of this question ...

plz mark my answer as brainlist plzzzz vote me also as I have done this question by taking a lot of time Hope it will be helpful for you ....

Marcy played the piano for 45 mins she stopped playing at 4:15 pm at what time did she start playing the piano
elixir [45]
We know that
1 hour----------> 60 min

step 1
convert hours to minutes
<span>4:15---------> 4 hour +15 minutes------> 4*60+15-----> 255 minutes

step 2
</span><span>subtract 45 minutes
</span>255-45--------> 210 minutes

step 3
convert to hour
1 hour----------> 60 min
x-----------------> 210 min
X=210/60---------> X=3.5 hour
3.5 hour
that means
3 hour+0.5 hour
and 0.5 hour is-----------> 0.5*60----> 30 minutes
therefore
3.5 hour-------> 3 hour +30 minutes-------->3:30 pm

the answer is
3:30 pm

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give
Doss [256]

Answer:

y=3x-3

Step-by-step explanation:

We are given that

y=ln x^3

Point (1,0)

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

\frac{dy}{dx}=\frac{1}{x^3}\times 3x^2}=\frac{3}{x}

\frac{d(lnx)}{dx}=\frac{1}{x}

Substitute x=1

m=\frac{dy}{dx}=3

Slope-point form:

y-y_1=m(x-x_1)

x_1=1,y_1=0

By using this formula

The equation of tangent to the given graph

y-0=3(x-1)=3x-3

y=3x-3

The length of a certain rectangle is twice its width. if the lenth is decreased by 3 cm, the area of the resultign recatangle is
Maslowich
Here's what we know:
l=2w
l*w=A [tex](l-3)*w=A-12

Now let's substitute in what we know from the first equation into the third equation:
(2w-3)*w=A-12
2w^{2}-3w=A-12
2w^{2}-3w+12=A=l*w=2w*w=2w^{2}
-3w+12=0
-3w=-12
w=4

Since we know the relationship between length and width:
l=2w=2*4=8

So l=8, w=4.
