For what point on the curve of y=8x^2 - 3x is the slope of a tangent line equal to -67
AleksandrR [38]

The point on the curve is (–4, 140)

Solution:

Given y=8x^2-3x and slope is –67.

slope = –67

$\frac{dy}{dx}=-67$  – – – – (1)

Now calculate \frac{dy}{dx} for the given curve y=8x^2-3x.

Using differential rule:

$\frac{d}{dx}(x^n)=nx^{n-1}

$\frac{dy}{dx}=\frac{d}{dx}(8x^2-3x)

    $=\frac{d}{dx}(8x^2)-\frac{d}{dx}(3x)

    $=(8\times2x^{2-1})-(3\times1x^{1-1})

    $=16x^1-3x^0

    $=16x-3

$\frac{dy}{dx}=16x-3 – – – – (2)

Equate (1) and (2).

16x-3=-67

16x=-67+3

16x=-64

⇒ x = –4

Substitute x = –4 in y.

⇒ y=8(-4)^2-3(-4)

⇒    =8(16)+12

⇒ y = 140

Hence, the point on the curve given is (–4, 140).

in the function y=-3x^2+1, what effect does the negative sign have on the graph, as compared to the graph of y=x^2
fgiga [73]

Answer:

see explanation

Step-by-step explanation:

Given a quadratic function in standard form y = ax² + bx + c ( a ≠ 0)

• If a > 0 the the graph has a minimum value ∪

• If a < 0 then the graph has a maximum value ∩

Thus y = - 3x² + 1 ← has a maximum value and

y = x² ← has a minimum value

The density of granite is about 2.75 grams per cubic centimeter. Suppose you have a granite countertop for a kitchen that is 1 m
Ugo [173]

Answer:

equation: 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)

Step-by-step explanation:

countertop mass, m =?

density, ρ = 2.75 g/cm^3

wide, w = 1 m

long,  l = 3 m

thick, t = 4 cm

countertop volume, V = w*l*t = 1 m *3 m*4 cm* (100 cm/1 m)^2

Isolating mass from density definition gives

ρ = m/V

m = ρ*V

m = 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)
