Answer:

  12. C

  13. D

Step-by-step explanation:

12. For interest r on principal P compounded n times per year for t years, the account balance is ...

  A = P(1 +r/n)^(nt)

For P=800, r=0.05, n=365, t=6, this becomes ...

  A = 800(1 +0.05/365)^2190 . . . . matches choice C

Note: if you're familiar with the formula, you will notice choice C is the only one with 'n' in the right place.

__

13. The form of an exponential function is ...

  y = a·b^x . . . . . . . . where 'a' is the initial value, and 'b' is the growth factor

The form of the equation eliminates choices A and B.

Here, the initial value is 1.87, eliminating choice C.

Matching the problem statement to the form of the exponential function we see that the equation of choice D is appropriate.

Given ∆ABC with vertices A(−4, −3), B(0, 0), C(2, −3) and ∆DEF with vertices D(3, 1), E(6, -3), F(3, −5), use the definition of
dimaraw [331]

By SSS congruency criteria ΔABC ≅ ΔDEF

<h3>What is congruency?</h3>

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The given vertices of the triangles are;

ΔABC: A(−4, −3), B(0, 0), C(2, −3)

ΔDEF:  D(3, 1), E(6, -3), F(3, −5)

The lengths of the sides of ΔABC are

AB = √((0+4)² + (0+3)²) = √25 = 5

BC = √((2-0)² + (-3 - 0)²) = √13  

AC = √((2+4)² + (-3 +3)²) = √36 = 6

The lengths of the sides of ΔDEF are;

DE = √25=5

EF = √13

DF = √36 = 6

As,

AB= DE, BC = EF , AC= DF

So, By SSS congruency criteria ΔABC ≅ ΔDEF

corine in making potato salad for each bowl of potato salad she needs 1/4 cup of potatoes how many cups of potatoes will she use
NARA [144]

Answer:

8 cups of potatoes are needed

Step-by-step explanation:

One way of doing this work is to write out

1/4 cup                                             1 cup

------------- , which is equivalent to  ------------ (a unit rate)

 1 bowl                                              4 bowl

and then multiply this unit rate by 32 bowls:

(1/4)(32 bowls) = 8 cups of potatoes are needed
