Answer: The graph is a parabola facing up ,

Step-by-step explanation:

Since the coefficient of $x^{2}$ is positive , then the graph is a parabola facing up.

The minimum point is at x = -2 ( using the formula for calculate vertex , x = $\frac{-b}{2a}$ )

And the y - intercept = 4

y= total cost

1 pound= $2

the $2 : constant

the number of pounds: variable

the equation is y=2x

1 pound: $2

2 pounds: $4

4 pounds: $8

5 pounds: $10

these also could be written as coordinates

the coordinates are (1,2),(2,4),(4,8),(5,10)

A ladder that is 32 ft long leans against a building. The angle of Elevation of the Ladder is 70 degrees

netineya [11]

Answer:

B. 30 ft

Step-by-step explanation:

The ladder is 32 ft long

The angle of elevation of the ladder is 70°

The height (h) of the top of the ladder to the ground is what we are to find.

$\frac{h}{32}$ = sin 70°

h = 32 × sin 70° = 30.07016387 or 30 ft (rounded off to nearest feet)

Help me please!! This is timed and I’m stuck

Let's solve

$\\ \sf\longmapsto 2x^2+7x-15=0$

$\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{7^2-4(2)(-15)}}{2(2)}$

$\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{169}}{4}$

$\\ \sf\longmapsto x=\dfrac{-7\pm13}{4}$

$\\ \sf\longmapsto x=\dfrac{-7+13}{4}\:or \:\dfrac{-7-13}{4}$

$\\ \sf\longmapsto x=\dfrac{6}{4}\:or\:\dfrac{-20}{4}$

$\\ \sf\longmapsto x=\dfrac{3}{2}\:or -5$

Subtract

$\\ \sf\longmapsto 3/2-(-5)=3/2+5=13/2$
