Answer:

Function 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point. Evaluating the two functions given:Function1: Function2 has value 3 for x=0So, Function 2 has a greater initial valueFunction 2 has a greater initial valueStep-by-step explanation:An initial value of a function, aka y-intercept, is obtained by using x=0 and evaluating the function at that point. Evaluating the two functions given:Function1: Function2 has value 3 for x=0So, Function 2 has a greater initial value

Answer:

x= 43.89

Step-by-step explanation:

Start off with your ratio. Because we're finding an angle, we'll use -1.

Since it's the opposite and adjacent, TAN is the ratio we're using here.

(tan is opposite/adjacent)

Tan -1x = 101/105

in your calculator, divide 101 and 101

=0.9619

then with this number, hit 2nd and Tan and enter and you will get

x= 43.89.

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$

Two triangles have the same base lengths. One Triangle has the height that is 4 times the height of the other triangle. Are the

Scrat [10]

YES

Area of Triangle 1

Base=b

Height= h

Area 1=A1=1/2*b*h

Area of Triangle 2

Base=b

Height= 4h

Area of triangle 2=A2=1/2*b*4h

Comparing A1 and A2

A2/A1= (1/2*b*4h)/(1/2*b*h)

= (1/2*b*4h)/(1/2*b*h)

=4/1

Ratio of heights =h2/h1= 4/1

Ratio of areas =A2/A1= 4/1

They are proportional.
