I agree. The answer is choice A.

There is a downward trend going on. As x gets larger, y seems to be getting smaller. Though we have a weak correlation because the points aren't all close to the same straight line. They seem to be randomly scattered.

Note: if we ignore the outlier, then the correlation gets a bit stronger, but not much so.

Expression: (5−2)2+23×4 Step 1: (3)2+23×4 Step 2: 9+23×4 Step 3: 9+9×4 Step 4: 9+36 Step 5: 45 Emily made a mistake. Which step
Levart [38]

Answer:

Step 3

Step-by-step explanation:

Given

(5 - 2)^ 2 + 23 * 4

Required:

Determine the first step where she made mistake

Her Step 1:

(3)^ 2 + 23 * 4 --- This is correct because she solved the bracket first

Her Step 2:

9 + 23 * 4 --- This is correct because she solved 3^2 as 9

Her Step 3:

9 + 9 * 4 --- This is incorrect because 23 * 4 is not equivalent to 9 * 4

Hence, her first mistake is in step 3.

The correct expression would have been

9 + 92

Then

= 101

Find the surface area of each figure round your answers to the nearest hundredth if necessary
Wewaii [24]

Answer: 410 square km

Step-by-step explanation:

The area of each of the triangles with their base on the 10 km side is A=\frac{1}{2}(10)(13.4), so their combined area is (10)(13.4)=134.

The area of each of the triangles with their base on the 12 km side is \frac{1}{2}(12)(13), so their combined area is (12)(13)=156.

The area of the bottom rectangular face is 10(12)=120.

So, the total surface area is 120+156+134=\boxed{410 \text{ km}^{2}}

The exponential function f(x) = 2^x undergoes two transformations to
Eddi Din [679]

Option A: It is vertically stretched

Option B: it is shifted down

Solution:

The exponential function f(x)=2^{x}undergoes two transformations to   g(x)=5 \cdot 2^{x}-3.

<u>To determine how the graph changes:</u>

Consider the given exponential function f(x)=2^{x}.

Let y = f(x)

Vertically compressed or stretched:

A vertically compression (stretched) of a graph is compressing the graph toward x-axis.

• if k > 1 , then the graph y = k• f(x) , the graph will be vertically stretched by multiplying each y coordinate by k.

• if 0 < k < 1 if 0 < k < 1 , the graph is f(x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.  

• if k should be negative, the vertical stretch or shrink is followed by a reflection across the x-axis.  

Here, k = 5  

So the graph will be vertically stretched.

Also, Adding 3 to the graph will move the graph 3 units down so, the graph is shifted down.

So, The graph is shifted down.  

Hence option A and option B is the correct answer.
