Answer:

m = n = 20

Step-by-step explanation:

Here, we want to find the missing side lengths

For a 45-45 triangle, the lengths have a side ratio of;

1:1: √2

We should understand that the triangle is isosceles ( opposite and adjacent are equal)

So n = m

So what we just need to do here is divide 20 √2 by √2

Mathematically, that would be;

20 √2/√2 = 20

Addinfg in scientific notation 9x10^3 +2.3x10^4=

Vladimir [108]

Answer:

3.2 × 10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Proving trapezoid theorems Geometry

Artist 52 [7]

Answer:

ΔABD ≅ ΔACD by SAS, therefore;

$\overline {BD} \cong \overline {CA}$ by CPCTC

Step-by-step explanation:

The two column proof is presented as follows;

Statement ${}$ Reason

ABCD is a trapezoid ${}$ Given

$\overline {BA} \cong \overline {CD}$ ${}$ Given

$\overline {BC} \parallel \overline {AD}$ ${}$ Definition of a trapezoid

ABCD is an isosceles trapezoid ${}$ Left and right leg are equal

∠BAD ≅ ∠CDA ${}$ Base angle of an isosceles trapezoid are congruent

$\overline {AD} \cong \overline {AD}$ ${}$ Reflexive property

ΔABD ≅ ΔACD ${}$ By SAS rule of congruency

$\overline {BD} \cong \overline {CA}$ ${}$ CPCTC

CPCTC; Congruent Parts of Congruent Triangles are Congruent

SAS; Side Angle Side rule of congruency

Answer:

Slope is -3

General Formulas and Concepts:

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

y = -3x

↓ Compare to y = mx + b

Slope <em>m</em> = -3

y-intercept <em>b</em> = 0

Find the average rate of change of g(x) =-x²+2x+2 from x=2 to x = 6.

Leokris [45]

Solve the equation replacing x with 2 and the 6:

-2^2 + 2(2) + 2 = 4 + 4 + 2 =10

-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50

Difference between the answers: 50-10 = 40

Difference between 2 and 6 = 6-2 = 4

Average rate of change = 40/4 = 10

The answer is 10
