Olin [163]

Answer:

The graph has only one x-intercept

Step-by-step explanation:

we have

$f(x)=-4x^2+12x-9$

we know that

The discriminant of a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$D=b^{2}-4ac$

in this problem we have

$f(x)=-4x^2+12x-9$

$a=-4\\b=12\\c=-9$

substitute

$D=12^{2}-4(-4)(-9)$

$D=144-144$

$D=0$

The discriminant is zero

That means ----> The quadratic equation has one real solution

The graph has only one x-intercept

Answer:

t = 25.05761543°

Step-by-step explanation:

sin (x) = 36/85 = 0.423529412

sin (x) = 0.423529412

x = sin^-1(0.423529412)

x = 25.05761543°

Write the following in point-slope form using the given information: Slope: 2 points

SCORPION-xisa [38]

Answer:

$y+5 = \frac{1}{15}(x - 3)}$

Step-by-step explanation:

Given

$m = \frac{1}{15}$ -- Slope

$(x_1,y_1) = (3,-5)$ --- Point

Required

Write an equation in point slope form

The point slope form of an equation is:

$y - y_1 = m(x - x_1)$

Substitute values for y1, x1 and m

$y-(-5) = \frac{1}{15}(x - 3)}$

$y+5 = \frac{1}{15}(x - 3)}$

Hence, the equation in point slope form is:

$y+5 = \frac{1}{15}(x - 3)}$

211m+16=4+611m<br> m=<br> find the sum to m

soldi70 [24.7K]

Answer:

m = 3/100

Step-by-step explanation:

211m + 16 = 4 + 611m

211m - 611m = 4 - 16

-400m = -12

m = -12/-400

m = 3/100
