Aschool club is raising money for a trip, and needs to reach $10,000. their fundraising progress is modeled by the function

f(x) = 435 + 1200x, where x is measured in weeks.

what is the meaning of the constant 435?

435 is the money that the school club have had already before the fundraising started.

Step-by-step explanation:

The school club modeled their fundraising progress with a linear function.

They will have a 1200 income every week, that's why they multiply 1200 by x, being x the number of weeks.(time)

435 is a fixed number that represents the amount of money that the club had before starting the fundraising

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
