1 answer:

5 0

8,14,20,26

8 to 14 is 6
14 to 20 is 6
20 to 26 is 6

The next term will be 26 + 6 = 32

Because there is a gap of 6 between each number

WHat is the missing height?

ololo11 [35]

Answer:

w = 4 cm

Step-by-step explanation:

recall that the area of a triangle is given by

A = (1/2) x base length x height

we are given:

A = 10 cm²

base length = 5 cm

height = w

substituting the values above into the equation,

A = (1/2) x base length x height

10 = (1/2) x 5 x w

20 = 5w

w = 20/5

w = 4 cm

Select the two values of x that are roots of this equation 3x^2 + 1 =5x

Zina [86]

Answer:

x = 1.434 and x=0.232

Step-by-step explanation:

To find the root of the equation stated above we need to:

(1) Write the polynomial equation with zero on the right hand side:

$3x^{2} + 1 = 5x$ ⇒ $3x^{2} -5x + 1 = 0$

(2) Divide the whole equation by 3

$3x^{2} -5x + 1 = 0$ ⇒ $x^{2} -\frac{5}{3}x + \frac{1}{3}= 0$

(3) Use the quadratic formula to solve the quadratic equation:

The quadratic formula states that the two solutions for a quadratic equation is given by:

$\frac{-b±\sqrt{b^{2} - 4ac}}{2a}$ (1)

In this case, a = 1, b = $-\frac{5}{3}, c= \frac{1}{3}$

Substituiting a, b and c in equation (1) We get:

$\frac{-\frac{5}{3}±\sqrt{(-\frac{5}{3})^{2} - 4(1)(\frac{1}{3})}}{2(1)}$ (1)

The two solutions are:

x = 1.434 and x=0.232
