Answer:

(4,11)

Step-by-step explanation:

y=2x+3

y=5x-9

the first equation is equal to the second equation so

2x+3=5x-9

put like terms together

2x-5x= -9-3

-3x= -12

divide both sides by -3

.•.x=4

now, use the value of x to find the value of y like this:

y=2x+3 (x=4)

y=2(4)+3

y=8+3

y=11

therefore, the two lines intersect at the point (4,11)

Colin invests £2200 into his bank account. He receives 2.5% per year simple interest. How much will Colin have after 3 years? Gi

Helga [31]

Answer:

Colin will have $2365 after 3 years.

Step-by-step explanation:

Using PRT/100, we can find the interest and then sum it up with the principle amount.

=> 2200 x 2.5 x 3/100 = Interest
=> 22 x 2.5 x 3 = Interest
=> 55 x 3 = Interest
=> 165 = Interest
=> 2200 + 165 = Total amount
=> $2365

Hence, Colin will have $2365 after 3 years.

We have to find horizontal component of Mayosons velocity.

$\\ \tt\bull\leadsto V_x=vsin\theta$

$\\ \tt\bull\leadsto V_x=2.5sin36$

$\\ \tt\bull\leadsto V_x=2.5(0.58)$

$\\ \tt\bull\leadsto V_x=1.45m/s$

Here 2 vectors A=8 and B=2.5

$\\ \tt\bull\leadsto \overrightarrow{R}$

$\\ \tt\bull\leadsto \sqrt{A^2+B^2+2ABcos\Theta}$

$\\ \tt\bull\leadsto \sqrt{8^2+2.5^2+2(8)(2.5)cos36}$

$\\ \tt\bull\leadsto \sqrt{64+6.25+40(0.8)}$

$\\ \tt\bull\leadsto \sqrt{70.25+32}$

$\\ \tt\bull\leadsto \sqrt{102.25}$

$\\ \tt\bull\leadsto 10.15m/s$
