Simplify. <br> (–5q^2p)^3
mr_godi [17]

Answer:

Step-by-step explanation:

(a*b)^{n} = a^{n}*b^{n}\\\\(a^{n})^{m} = a^{m*n}\\\\ (-5q^{2}*p)^{3}= (-5)^{3}*q^{2*3}*p^{3}\\\\= -125q^{6}p^{3}

5x3 + 9x² - 13x - 2<br>As x approaches --, f(x) approaches<br>As x approaches +o, f(x) approaches​
Solnce55 [7]

9514 1404 393

Answer:

  (x, y) → (-∞, -∞), (+∞, +∞)

Step-by-step explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

  x → -∞, f(x) → -∞

  x → ∞, f(x) → ∞

Write an equation in standard form of a line that passes through (4, 2) and is parallel to y = - 3/4 * x - 5 .
Bingel [31]

Answer:

y=2x+y-int

Step-by-step explanation:

If the line is parallet to the defined by the given equation the slope of the unknown line is m=2.

Use this value of slope to calculate the y intercept. 2  = ( 2 - y-int)/4 - 0)

THus, your equation is y = 2x + y-int

Evaluate if m=1 and n=2 what’s 15m/n+1-m^2+n
Jobisdone [24]

\\ \sf\longmapsto \dfrac{15m}{n}+1-m^2+n

\\ \sf\longmapsto \dfrac{15(1)}{2}+1-(1)^2+2

\\ \sf\longmapsto \dfrac{15}{2}+3-1

\\ \sf\longmapsto \dfrac{15}{2}+2

\\ \sf\longmapsto \dfrac{15+4}{2}

\\ \sf\longmapsto \dfrac{19}{2}

Help me please :''c​
wlad13 [49]

Answer:

9) QR = 4.0

10) AC = 4.1

Step-by-step explanation:

Tan = Opps. / Adj.

9)

Tan(60) = 7 / QR

QR = 7 / Tan(60)

QR = 7 / 1.732

QR = 4.0415

QR = 4.0

10)

Tan (27) = AC / 8

AC = Tan(27) * 8

AC = 0.5095 * 8

AC = 4.076

AC = 4.1
