Answer:

Step-by-step explanation:

Given:

m∠NPT = m∠TNM = 50°

To prove:

ΔNMT ~ ΔPMN

Solution:

Statements Reasons

1). m∠NPT = m∠TNM 1). Given

2). ∠NMP ≅ ∠NMP 2). Reflexive property

3). ΔNMT ~ ΔPMN 3). By AA property of similarity of two

Determine which of the following graphs is the graph of 8x + 9y - 72.

Fittoniya [83]

Step-by-step explanation:

To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.

Step 1: 8x + 9y - 72 = 0

Step 2: 8x + 9y = 72

Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C

Y-INTERCEPT (vertical line): ( $\frac{c}{b}$ , 0 )

X-INTERCEPT (horizontal line): ( 0 , $\frac{c}{a}$ )

Insert your numbers how it shows in the standard form equation and you should get something like this:

Y-INTERCEPT: ( $\frac{72}{9}$ , 0 )

Simplified Y-INTERCEPT: ( 8 , 0 )

X-INTERCEPT: ( 0 , $\frac{72}{8}$ )

Simplified X-INTERCEPT: ( 0 , 9 )

Insert that into your graph and you should be able to get your answer.

A triangle has a priemeter of 39 units . Each side of this triangle is the same length. What is the length of one side of the tr

Readme [11.4K]

This is easier to understand with a picture...

We know that a triangle has 3 sides right?

Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides

39/3=13

Therefore, one side of the triangle would equal 13

A dog owner observes that from birth to age 14 weeks, the puppy’s weight can be modelled by the equation w=365×(1.23)t , for (0≤

Fantom [35]

Answer and Step-by-step explanation:

(1) Scale factor is a constant value that multiplies another value. For a puppy's weight, scale factor is 1.23.

The percentage growth is

1.23 = 1 + 0.23

Percentage is 0.23 or 23%.

(2) Equation for increase is

$w=365(1.23)^{t}$

When w = 4000g:

$4000=365(1.23)^{t}$

$(1.23)^{t}=\frac{4000}{365}$

$1.23^{t}=10.96$

Using the log law:

$log_{b} (M^{k}) = klog_{b}(M)$

$log(1.23^{t})=log(10.96)$

t.log(1.23) = log(10.96)

0.08990t = log(10.96)

$t=\frac{log10.96}{0.08990}$

t = 11.56

The puppy will weigh 4000 grams in 11 and half weeks or between 11 and 12 weeks.
