Answer:

Because the triangle is isosceles, the base angles are congruent. Since the sum of angles in a triangle is 180° we can write:

24 + x + x = 180

24 + 2x = 180

2x = 156

x = 78°

Answer:

$\boxed{x=78}$

Step-by-step explanation:

The triangle is an isosceles triangle.

The two base angles are equal.

Angles in a triangle add up to 180 degrees.

x + x + 24 = 180

Combine like terms.

2x + 24 = 180

Subtract 24 on both sides.

2x = 156

Divide both sides by 2.

x = 78

Find the directional derivative of f(x,y,z)=z3−x2yf(x,y,z)=z3−x2y at the point (−5,5,2)(−5,5,2) in the direction of the vector v

olga_2 [115]

We are given

$f=z^3 -x^2y$

Firstly, we can find gradient

so, we will find partial derivatives

$f_x=0 -2xy$

$f_x=-2xy$

$f_y=0 -x^2$

$f_y=-x^2$

$f_z=3z^2$

now, we can plug point (-5,5,2)

$f_x=-2*-5*5=50$

$f_y=-(-5)^2=-25$

$f_z=3(2)^2=12$

so, gradient will be

$gradf=(50,-25,12)$

now, we are given that

it is in direction of v=⟨−3,2,−4⟩

so, we will find it's unit vector

$|v|=\sqrt{(-3)^2+(2)^2+(-4)^2}$

$|v|=\sqrt{29}$

now, we can find unit vector

$v'=(\frac{-3}{\sqrt{29} } , \frac{2}{\sqrt{29} } , \frac{-4}{\sqrt{29} })$

now, we can find dot product to find direction of the vector

$dir=(gradf) \cdot (v')$

now, we can plug values

$dir=(50,-25,12) \cdot (\frac{-3}{\sqrt{29} } , \frac{2}{\sqrt{29} } , \frac{-4}{\sqrt{29} })$

$dir=(-\frac{150}{\sqrt{29} } - \frac{50}{\sqrt{29} } - \frac{48}{\sqrt{29} })$

$dir=-\frac{248\sqrt{29}}{29}$ .............Answer

For the function h(x) =3x/(x+5)(x-4), solve the equation.

LuckyWell [14K]

Answer:

x = 0

Step-by-step explanation:

To 'solve' means to find the x values that make the equation equal zero, so

0 = (3x)/[(x + 5)(x - 4)

Multiply both sides by the denominator to get rid of the fraction

0[(x + 5)(x - 4)] = [(3x)(x + 5)(x - 4)]/[(x + 5)(x - 4)]

0 = 3x

0 = x (divide both sides by 3)

So x = 0 is the solution for this equation

joe earns R25 per hour working at a pizza shop. How much will he earn over a weekend of two shifts, each six hours long

NeX [460]

Answer:

R300

Step-by-step explanation:

To solve:

Multiply 25 by 6 to represent the earnings of a shift.
Multiply the shift earnings by 2 to represent how much he earned over the weekend.

Multiply 25 by 6:

$25 \times 6 = 150$

Multiply 150 by 2:

$150 \times 2 = 300$

Joe will earn R300 over the weekend,

-3x+6 = -4x

6 = -x

x = -6

check:

-6*-3 = 18 +6 =24

-6*-4 = 24
