Answer:

$Q(a) = w$

Step-by-step explanation:

Given

w = weight

a = age

Required

Represent the weight as a function of age

When writing a function.

$y = f(x)$

means that y is a function of x

Using the above to answer the given question, we have:

$w = Q(a)$

Which means w is a function of a

and can be rewritten as:

$Q(a) = w$

lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

$\frac{1+Cos2x}{Sin2x}$

We have to verify the identity.

We know that

$1+Cos2x=2Cos^2 x$

$Sin2x=2SinxCos x$

Using the formula

$\frac{2Cos^2x}{2SinxCosx}$

$\frac{Cosx}{Sinx}$

$Cot x$

By using the formula

$Cotx=\frac{Cosx}{Sinx}$

LHS=RHS

Hence, verified

the high school debate team is developing a logo to represent their club. A scale drawing of the logo design is presented below,

Fantom [35]

Answer:

The enlargement will be 25 times and the enlargement area will be $2250 \text{ inches}^2$ .

Step-by-step explanation:

It is given that each grid unit is equal to 3 inches. SO we have to use this scale.

The total height of the scale drawing is 21 inch and the enlargement has a height given as 105 inches. Therefore it has scale factor of 5. It means that each dimension is enlarged by 5 times the dimension in the scale drawing. So the enlargement of the logo will be 25 times and the enlargement area will be 2250 square inches.

The function g(x) is defined by the equation g(x) = -3x² + x - 1.<br> Which is the value of g(1)?

Nutka1998 [239]

Answer:

-3

Step-by-step explanation:

g(1) = -3x² + x - 1

= -3( $1^{2}$ ) + 1 -1

= -3(1) + 1 - 1

= -3 +1 -1

g(1) = -3

Just put the 1 everywhere you see an x.
