What is the dollar amount of the Gentry's annual food and housing budgets combined?

Pavlova-9 [17]

Answer:

The combined amount is $14871.21.

Step-by-step explanation:

It is given that, the total yearly income of gentry family is $29742.42

The % charge on income for food is 20%.

The % charge on income for housing is 30%.

The amount in dollar from % form is given by,

= $(\frac{percent form}{100})(annual income)$

For annual food,

= $(\frac{20}{100})(29742.42)$

= $5948.484

For housing budgets,

= $(\frac{30}{100})(29742.42)$

= $8922.726

Thus the combined amount is,

= $8922.726 + 5948.484 = 14871.21$

= $14871.21

Prove that:- (1-sinA)(1+sinA)÷(1+cosA)(1-cosA)=cot^2A

astraxan [27]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x and cos²x = 1 - sin²x

Consider the left side

$\frac{(1-sinA)(1 + sinA)}{(1+cosA)(1-cosA)}$ ← expand numerator/denominator using FOIL

= $\frac{1-sin^2A}{1-cos^2A}$

= $\frac{1-(1-cos^2A)}{1-(1-sin^2A)}$

= $\frac{1-1+cos^2A}{1-1+sin^2A}$

= $\frac{cos^2A}{sin^2A}$

= cot²A = right side , thus proven

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

gavmur [86]

Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .
