A parallelogram has sides of length 16 units and 10 units. The shorter diagonal is 11 units. Find the measure of the longer diag

lord [1]

The measure of the longer diagonal is 24.31 units

<h3>How to determine the longer diagonal?</h3>

The side lengths are given as;

a = 16

b = 10

The shorter diagonal is represented as d1, and it is given as

d1 = 11

The longer diagonal is represented as d2, and it is calculated using

d1^2 + d2^2 = 2 * (a^2 + b^2)

Substitute the known values in the above equation

11^2 + d2^2 = 2 * (16^2 + 10^2)

Evaluate the sum

121 + d2^2 =2 * 356

Evaluate the product

121 + d2^2 = 712

Subtract 121 from both sides

d2^2 = 591

Take the square root of both sides

d2 = 24.31

Hence, the measure of the longer diagonal is 24.31 units

What are the zeros of the polynomial function? f(x)=x2−12x+20 Enter your answers in the boxes. The zeros of f(x) are and

Schach [20]

$f(x)=x^{2} -12x+20$
$f(x)=0$
x $x^{2} -12x+20=0$
Factoring:
$(x-2)(x-10)=0$
Two possible soolutions:

$x-2=0 [tex]x=2$

$x-10=0$
$x=10$

The zeros of the polynomial function are x=2 and x=10

a scalene triangle has an area of 20.335 square centimeters. the height of the triangle is 8.3 centimeters. what is the length o

UNO [17]

Area of triangle = (1/2)*base*height

20.335 = (1/2)*base*8.3

2*20.335 = base*8.3

(2*20.335) / 8.3 = base Use your calculator.

4.9 = base

base = 4.9cm
