PLEASEEEEE HELLPPP!!!

Mathematics
1 answer:
Veseljchak [2.6K]3 years ago
7 0

Answer:

4

Step-by-step explanation:

f(x) (8x² - 3x + 1) / (2x² + 2x +3)

the first thing I did was to graph the function to see if there was a horizonal asymptote using Desmos graphing calculator and there was and it was 4

you want to take the limit as x approaches infinity

essentially  lim(x to ∞) of f(x) = 8x²/ 2x²      is the dominate terms

                    lim(x to ∞) of f(x) = 8 / 2

                    lim(x to ∞) of f(x) = 4

-4x+8y=-256 -6y = x. how do u solve this equation by substitution.
serious [3.7K]
To make it soo much easier, divide top equation by 4
-x+2y=-64

now
-6y=x
sub -6y for x
-(-6y)+2y=-64
6y+2y=-64
8y=-64
divide both sides by 8
y=-8

sub back
-6y=x
-6(-8)=x
48=x

x=48
y=-8
(x,y)
(48,-8)

x(1,4,5)=4
y(1,4,5)=100

z_s=z_xx_s+z_yy_s=(4x^3+2xy)(1)+x^2(tu^2)
z_s(1,4,5)=1,024,000

z_t=z_xx_t+z_yy_t=(4x^3+2xy)(2)+x^2(su^2)
z_t(1,4,5)=1,331,200

z_u=z_xx_u+z_yy_u=(4x^3+2xy)(-1)+x^2(2st)
z_u(1,4,5)=-450,560

Write an equation for the line that passes through (-1,4) with a slope of -10
Maurinko [17]

Answer:

y = - 10x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here slope m = - 10, hence

y = - 10x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = 10 + c ⇒ c = 4 - 10 = - 6

y = - 10x - 6 ← equation of line

Help me solve for the right triangle
AleksAgata [21]

Answers:

B = 50

a = 10.9

c = 17.0

================================================

Explanation:

This is a right triangle, so the acute angles are complementary, meaning they add to 90

B+40 = 90

B+40-40 = 90-40

B = 50

Also, because this is a right triangle, we can use trig ratios to compute the missing sides

tan(angle) = opposite/adjacent

tan(40) = a/13

a = 13*tan(40)

a = 10.908

a = 10.9

cos(angle) = adjacent/hypotenuse

cos(40) = 13/c

c*cos(40) = 13

c = 13/cos(40)

c = 17.0

note: make sure your calculator is in degree mode

Which pair of values could NOT be the roots of a quadratic polynomial?
DENIUS [597]

Answer:

Part c

Step-by-step explanation:

In quadratic equations of real coefficients, the complex roots always occur in conjugate bases. It means, if, 2 + 3i is one of the roots and then the second root must be 2 - 3i.
