The triangles below are similar find the value of a. it is 10 on the left side 10 on the right and 6 at the bottom and on ther other triangle its 5 on each sides and a at the bottom

a.10
b. 3
c. 2.5
d. 6

the triangles are similar. find the value of a. it is 16 on the left side and 20 on the right on the other triangle a on the left side s on the right

a. = 12
b. a = 6
c. a = 10
d. a = 16

step-by-step explanation:

abc

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
