Solve for x: x^2 + 28x = 60

Alisiya [41]

For this case we have a quadratic equation, $x ^ 2 + 28x-60 = 0$ , of the form $ax ^ 2 + bx + c = 0$

Where:

$a = 1\\b = 28\\c = -60$

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.

These numbers are:

$+30\ and\ -2\\+ 30-2 = + 28\\+ 30 * -2 + -60$

Then, the factorization is given by:

$(x-2) (x + 30) = 0$

The roots are:

$x_ {1} = 2\\x_ {2} = - 30$

Answer:

$x_ {1} = 2\\x_ {2} = - 30$

A pole, 4m high, stands, vertically, on

Lostsunrise [7]

Answer:

Length of the shadow of the pole is 6.93 metres

Step-by-step explanation:

Given:

Height of the pole = 4 m

The angle sun makes with the horizontal = 30 degrees

To Find:

Length of the shadow of the pole = ?

Solution:

The tangent ratio is the value received when the length of the side opposite of angle theta is divided by the length of the side adjacent to angle theta

Let x be the length of the shadow

According to the tangent ratio

$tan {\theta} = \frac{opposite}{adjacent}$

On substituting the values,

$ta( {30^{o}) = \frac{4}{x}$

$x = \frac{4}{tan ({30^{o})}}$

$x =\frac{4}{0.57735027}$

x = 6.93 m

Evaluate v(x) = 14-3x when x=-3, 0 and 4.

PtichkaEL [24]

Answer:

$v(-3)=23\\v(0)=14\\v(4)=2$

Step-by-step explanation:

$v(x)=14-3x$

$v(-3)=14-3(-3)\\\\v(-3)=14-(-9)\\\\v(-3)=23$

$v(0)=14-3(0)\\\\v(0)=14-0\\\\v(0)=14$

$v(4)=14-3(4)\\\\v(4)=14-12\\\\v(4)=2$
