Answer:

The length of YZ is 22.30mm.

Step-by-step explanation:

Basically we need to find the hypotenuse of the triangle, or the longest side.

The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)

First we need to multiply 14.3 and 17.1 to the second power.

14.30 × 14.30 = 204.49

17.10 × 17.10 = 292.41

Now we add our two sums.

204.49 + 292.41 = 496.90

Now we need to find the square root of 496.90, which is 22.2912539.

Rounded to the nearest DP(Decimal point), it's 22.30

What is the value of the smaller zero of the function defined by 2x2 + 9x + 7?

lyudmila [28]

Answer:

We can factor the quadratic function into (2x + 7)(x + 1) and this way, the terms sum to 2x^2 + 9x + 7. Looking at the 2 factors 2x+7 and x+1, the way to find the zeros is to set both of these expressions equal to 0. Therefore we have: 2x+7=0

What is the slope of a line perpendicular to the line whose equation is 4x−10y=404x−10y=40. Fully simplify your answer.

Anna007 [38]

Answer:

$- \frac{5}{2}$

Step-by-step explanation:

4x -10y= 40

Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.

10y= 4x -40

Divide both side by 10:

$y = \frac{2}{5} x - 4$

The product of the gradients of perpendicular lines is -1.

⅖(gradient of line)= -1

Gradient of perpendicular line

$= - 1 \div \frac{2}{5}$

$= - 1 \times \frac{5}{2}$

$= - \frac{5}{2}$

What is the address of the element -5 in the matrix below?

Musya8 [376]

we have to find address of element -5 in the matrix

We know that

horizontal line represents number of rows

vertical line represents number of columns

We can see that

-5 is in third row

and -5 is in second column

Suppose, we have element in matrix

$b_m_n$

Here , m is number of rows

and n is number of columns

so, we got

$m=3$

$n=2$

now, we can plug these values

and we get

$b_3_2$ ............Answer
