2. the ans is C because 3 sides in option C keep the same ratio as the 3 sides of triangle NOP: 7.5/5=1.5, 10.5/7=1.5 and 13.5/9=1.5

3. the ans is D
just see from the point Q(16,4), after the first dilation, the x-coordinate of Q=16*0.25=4, then by subtracting 4 from the x-coordinate of point T (i.e. -2-4=-6), then you can see only option D has the x-coordinate (x-6), so it shows that it is the ans

4. i dont know about this.. sorry :(

Find the slope by changing form Standard Form to Slope Intercept Form<br> 7x- 8y = -56

Sholpan [36]

Answer:

y = 7/8x + 7

Step-by-step explanation:

7x- 8y = -56

-7x -7x

-8y = -7x - 56

y = 7/8x + 7

2 5/8 × 4 = 10 1/2

Charlie does not have enough wood because 10 1/2 is also equal to 10 4/8 and Charlie only has 10 3/8

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15. N an 1 4 2 −12 3 36 t

Rzqust [24]

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is $\sum_{n=4}^{15} 5(-2)^{n-1}$$$

<h3>What is sequence ?</h3>

Sequence is collection of numbers with some pattern .

Given sequence

$a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20$

We can see that

$\frac{a_1}{a_2}=\frac{-10}{5}=-2\\$

and

$\frac{a_2}{a_3}=\frac{20}{-10}=-2\\$

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now $n^{th}$ term of this Geometric progression can be written as

$T_{n}= 5\times(-2)^{n-1}$

So summation of 15 terms can be written as

$\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$$

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is $\sum_{n=4}^{15} 5(-2)^{n-1}$$$
