Answer:

15) K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Step-by-step explanation:

We are to find the derivative of the questions pointed out.

15) K(t) = 5(5^(t)) - 2(3^(t))

Using implicit differentiation, we have;

K'(t) = 5[5^(t)•In 5] - 2[3^(t)•In 3]

19) P(w) = 2e^(w) - (2^(w))/5

P'(w) = 2e^(w) - (1/5)[2^(w)•In 2]

20) Q(W) = 3w^(-2) + w^(-2/5) - w^(¼)

Q'(w) = -6w^(-2 - 1) + (-2/5)w^(-2/5 - 1) - ¼w^(¼ - 1)

Q'(w) = -6w^(-3) - (2/5)w^(-7/5) - ¼w^(-¾)

Hector is making an art project by cutting and gluing fabric shapes to a wooden board. His design includes two similar triangles

spin [16.1K]

Answer:

Center of dilation origin, The scale factor is 4, The dilation mapping is (x, y) → (4x,4y) and The image represents the shape of the triangle.

Step-by-step explanation:

Given Hector is making an art project by cutting and gluing fabric shapes to a wooden board. His design includes two similar triangles, with one 4 times the size of the other. He cuts the smaller fabric triangle and traces it onto grid paper. we have to tell how he can use the tracing to make a pattern for the larger fabric triangle.

Apply the center of dilation origin.

The scale factor is 4

The dilation mapping is (x, y) → (4x,4y)

The image represents the shape of the triangle.

You and your friends Jose and Sarah all live on the same street. You know that Jose lives five blocks from away from you. Jose s

Mila [183]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sarah, Jose and you live in the same street:

Distance between you and Jose = 5 blocks

Distance between Jose and Sarah = 2 blocks

Distance (b) between you and Sarah:

Since it isn't stated whether Sarah lives closer to you than Jose or vice versa ;

Then;

Distance b between you and Sarah will be :

(Distance between you and Jose ± distance between Jose and Sarah)

b = (5 ± 2)

b = (5 + 2) or (5 - 2)

b = 7 blocks or 3 blocks

Jack did 3/5 of all problems on his weekend homework before Sunday. On Sunday he solved 1/3 of what was left and the last 4 prob

Snezhnost [94]

Answer:

$\text{Problems assigned for weekend are}\frac{11}{15}x+4$

Step-by-step explanation:

Given that Jack did 3/5 of all problems on his weekend homework before Sunday. On Sunday he solved 1/3 of what was left and the last 4 problems. We have to find the number of problems assigned for weekend.

Let the total problems be x

$\text{Problems solved by Jack before Sunday}=\frac{3}{5}x$

$\text{Problems solved by Jack on Sunday}=\frac{1}{3}(x-\frac{3}{5}x)+4=\frac{1}{3}\times \frac{2}{5}x+4=\frac{2}{15}x+4$

∴ Problems assigned for weekend are

$\frac{3}{5}x+\frac{2}{15}x+4$

⇒ $\frac{11}{15}x+4$
