1 answer:
Virty [35]3 years ago
8 0

Answer:

No

Step-by-step explanation:

y = 3x + 4      If x=2   And    y=10

10 = 3*2 + 4

10 = 10           that’s a solution for this equation

y = x + 7      if x=2    and    y=10

10 = 2 + 7

10 (is not) = 9       That’s not a solution for this equation.

nikdorinn [45]
Circumerence=2pir or dpi were r=radius and d=diameter
11pi=2pir
divid eobt sides by pi
11=2r
dvide 2
5.5=r

11pi=dpi
divide both sides by pi
11=d

diameter=11in
radius=5.5 in

Can someone please help me
saw5 [17]

Answer:

-3

Step-by-step explanation:

The wording is basically saying the y-intercept so when it talks about initial value thats what its talking about. Its negative because it's on the further down side of the y axis. Y-intercept is where the line of a graph crosses the y axis like shown in the picture it is at -3.

* ANSWER PLS TY!! * Find the surface area of this cone.
vagabundo [1.1K]

Answer:

<h2>200 \: \pi</h2>

Step-by-step explanation:

Given,

R = 8 m

H = 15 m

Slant height :

=  \sqrt{ {r}^{2}  +  {h}^{2} }

=  \sqrt{ {(8)}^{2} +  {(15)}^{2}  }

=  \sqrt{64 + 225}

=  \sqrt{289}

=  \sqrt{ {(17)}^{2} }

= 17 \: m

Now, Finding the surface area of the cone:

\pi \: r(r + s)

Plugging the values:

= \pi \:  \times 8(8 + 17)

= 8\pi \:  \times 25

= 200 \: \pi

Hope this helps...

Good luck on your assignment...
