If f(x) = 25 -x^2 and g(x) = x + 5, what is (f/g)(x)? <br>Write your answer in the simplest form.

nikdorinn [45]

Answer:

Step-by-step explanation:

We are asked to divide the first equation f(x) by the second equation g(x) and then multiply the division by x

We will be using the difference of two squares to solve this question somewhere in the process

(f/g) * x

(25-x^2) / (x+5) * x

Bill is trying to plan a meal to meet specific nutritional goals. He wants to prepare a meal containing rice, tofu, and peanuts

Novay_Z [31]

Answer:

11.33 cups

Step-by-step explanation:

240 grams of carbohydrates: x

40 x + 4 x + 26 x = 240

X = 240/70

X = 3 3/7 cups

332 grams of fats = y

0y + 13y + 70y = 332

Y = 332/83

Y = 4 cups

207 grams of proteins = z

5z + 21z + 27z = 207

Z = 207/53

Z = 3 48/53 cups

3 3/7 + 4 + 3 48/53 = 11.33 cups

Suppose A,B and C are 2 ×2 matrices , E,F and G are 3 × 3 matrices, H and K are 2×3 matrices and L and M are 3×2 matrices. For e

Alekssandra [29.7K]

Answer:

a) 2x2 b)3x3 c) Not possible d) 2x3 e) 3x2 f) 3x3 g)Not possible h)3x2

Step-by-step explanation:

-> we can only add matrices with same size

-> we can only multiply when columns of first equal to rows of second

-> nxm multiplied by pxq gives nxq eg 3x2 mul 2x2 gives 3x2

-> addition and mul by const number dont change the size

So considering the above facts :-

a) AB+C = [(2x2)(2X2)]+(2x2)=(2x2)+(2x2)=2x2

b) 3GF =3[(3x3)(3x3)]=3(3x3)=3x3

c)CK+B= [(2x2)(2x3)]+(2x2)=(2x3)+(2x2) which is not possible (see point 1)

d)CK+H =as CK is (2x3) so (2x3)+(2x3)=(2x3)

e)EMC=[(3x3)(3x2)](2x2)=(3x2)(2x2)=3x3

f)GLH=[(3x3)(3x2)](2x3)=(3x2)(2x3)=3x3

g)HLG=[(2x3)(3x2)](3x3)=(2x2)(3x3)= not possible(see point 2)

h)2EL+5MB=2[(3x3)(3x2)]+5[(3x2)(2x2)]=(3x2)+(3x2)=3x2
