Factor 26r3s + 52r5 – 39r2s4.
algol [13]

Answer:

13r²(2rs + 4r³ - 3s⁴)

Step-by-step explanation:

In equation 26r³s + 52r⁵ - 39r²s⁴;

The GCF of 26, 52, and 39 = 13

The GCF of r³, r⁵ and r² = r²

The GCF of s, (no "s"), and s⁴ = no "s" (Since one of the number doesn't have "s")

Now we can factor out 13r² from all three expressions;

26r³s + 52r⁵ - 39r²s⁴

=> <em>13r²(2rs) + 13r²(4r³) - 13r²(3s⁴)</em>

To factor it all together;

<u>13r²(2rs + 4r³ - 3s⁴)</u>

Hope this helps!

Give the rule for the translation if the coordinates of the preimage are A(2,-4) B(5,-4) C(5,-2) D(4,-2) E(4,-1) F(3,-1) G(3,-2)
trasher [3.6K]

Answer:

  (x, y) ⇒ (x -7, y)

Step-by-step explanation:

The y-coordinates are unchanged. Each x-coordinate of the image is 7 units less than the corresponding pre-image coordinate. As a rule, this is ...

  (x, y) ⇒ (x -7, y)

1.Find the amount in an account where $200 is invested at 3.5% compounded quarterly for a period of 3 years.
spayn [35]

Part 1 :

P = $200

r = 3.5% or 0.035

t = 3

n = 4

Compound interest formula = P(1+\frac{r}{n})^{nt}

= 200(1+\frac{0.035}{4})^{3*4}

= 200(1.00875)^{12}

= 200\times1.1102

= 222.04

So, money in the bank will be = 200+222.04 = $422.04

Part 2 :

P = $200

r = 3.5% or 0.035

t = 3

Continuous compound interest formula is =

A = Pe^{rt}

Putting e =  2.71828 we get.

A = 200(2.71828)^{0.035*3}

= 200(2.71828)^{0.105}

= 200*1.11071 = 222.14

Hence, amount in account after 3 years will be= 200+222.14 = $422.14
