Answer 13

Explanation: Those lines mean absolute value and it's the numbers's distance from 0 so -13 will be 13, all negative numbers turn positive if its in between those numbers and positive numbers do nothing.

What is the axis of symmetry of the parabola y= 1/3 (x-10)^2 - 6

GalinKa [24]

Answer:

The equation of the axis of symmetry is equal to

$x=10$

Step-by-step explanation:

we have

$y=\frac{1}{3}(x-10)^2-6$

This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)

The vertex represent a minimum

The axis of symmetry is equal to the x-coordinate of the vertex

we have that

The vertex is the point (10,-6)

The x-coordinate of the vertex is 10

therefore

The equation of the axis of symmetry is equal to

$x=10$

Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = ___ (x +11)2 +____.

wel

$The\ vertex\ form:\\\\f(x)=a(x-h)^2+k$

$\text{Use}\ (a+b)^2=a^2+2ab+b^2\qquad(*)$

$g(x)=4x^2+88x=4(x^2+22x)=4(x^2+2\cdot x\cdot11)\\\\=4(\underbrace{x^2+2\cdot x\cdot11+11^2}_{(*)}-11^2)=4[(x+11)^2-121]=4(x+11)^2+(4)(-121)=4(x+11)^2-484$

Two upward forces are acting on a bolt. One force of 60.5lb acts at an angle of 82.4 above the horizontal and the other force of

Lera25 [3.4K]

Answer:

Fv = 79.63 lb

The total upward force Fv is 79.63 lb

Step-by-step explanation:

We need to determine the total upward force, the y component of force;

Given;

Force F1 = 60.5 lb, 82.4° above horizontal

Force F2 = 37.2 lb, (82.4-50.5)° above horizontal

The vertical component of Force F1 and F2 is;

Fv = 60.5sin(82.4) + 37.2sin(82.4-50.5)

Fv = 79.63 lb

The total upward force Fv is 79.63 lb
