shown below?

Answers

Answer:

Surface area of square pyramid = 380 m²

Step-by-step explanation:

Given:

Side of square base =10 m

Height of Square pyramid = 14 m

Find:

Surface area of square pyramid

Computation:

Surface area of square pyramid = Surface area of Base + 4[Surface area of triangle]

Surface area of square pyramid = [side x side] + 4[(1/2)(b)(h)]

Surface area of square pyramid = [10 x 10] + 4[(1/2)(10)(14)]

Surface area of square pyramid = 100 + 4[70]

Surface area of square pyramid = 100 + 280

Surface area of square pyramid = 380 m²

At a middle school, 74 students have freckles. There are 258 students in the school. To the nearest tenth of a percent, what percent of the students have freckles?

Answers

If there are 258 kids total in school, then let’s take it as 100%
And 74 kids have freckles, so we have to find the % of those kids with freckles.
258–100%
74-?%

Let’s find 1% of the kids.
258/100=2.58

Now let’s find the % of 74 kids.
74/2.58=28.68%~28.7%
(The percent of the kids with freckles is 28.7%)

total counted: 102
tagged counted: 38
total tagged: 56
21.

total counted: 958
tagged counted: 210
total tagged: 305

Answers

Answer:

Step-by-step explanation:

Step 1. (The capture) Capture a sample  total counted =958, and them back tagged counted=38,total tagged=56

The idea is to estimate the proportion p = m/N of tagged =102.

Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.

It is reasonable that, k/n would be a good estimante for p = m/N.

Accordingly, for an estimate N of N, se solve the equation m/N= k/n.

Step-by-step explanation:

The zeros of the graph are x = - 4 and x = 2 , then the factors are

(x + 4)(x - 2) and

y = a(x + 4)(x - 2) ← a is a multiplier

To find a use any other point on the graph and substitute into the equation

Using (0, - 8 ) , then

- 8 = a(4)(- 2) = - 8a ( divide both sides by - 8 )

1 = a

y = (x + 4)(x - 2) = x² + 2x - 8

with b = 2 and c = - 8

Horizontal

Step-by-step explanation:

The mathematical definition of slope is very similar to our everyday one. In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run.

Erik transformed the equation y = 2(x − 2)2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)2 + 5
y = 2(x2 − 4x + 4) + 5
y = 2x2 − 8x + 8 + 5
y = 2x2 − 8x + 13


answer choices


No. The error is in the second line: the expanded form of (x − 2)2 is x2 − 4.

No. The error is in the third line: the product of 2 and x2 − 4x + 4 is 2x2 − 4x + 4.

No. The error is in the fourth line: the sum of 8 and 5 is 12.

Yes. Erik is correct in his transformation from vertex form to standard form.

Find the exact value of each trigonometric function using the unit circle ​

Answers

Answer:

Step-by-step explanation:

use the co-terminal idea Scarlett,  990° = 270 °.  You can see this just by looking at the picture.

Tan(270 ) = sin(270) / cos(270)  = -sin(90) / cos(90)   so now we know that Tan(270) is one of the non-existant angles b/c  cos(90) = 0 and that would mean that we have some number over 0... and then the universe blows up.. like my calc II professor liked to say  :| I think he was being a bit dramatic. :P anyway,  you want answers not long boring stories.. :D   so Tan(270)           DNE  ( does not exist )

If we were to look at a graph of Tan  , we'd see that at 270° or 3[tex]\pi[/tex]/2 ,  Tan runs off to infinity.   So there isn't a number to represent it.  :/    I'm attaching a picture of the  graph

notice in the graph, that when tan gets to 3/2,  it's running off to infinity ??

I have 0.0254 it and they say approximately to 2 decimal place will I include the 0 after the decimal point​

Answers

Yes. You have to include 0.

If we round off this value to 2 decimal places then it is

0.03

Reason: after decimal point or before decimal point if you have to drop some digits and if the digit to be droped are 5 followed by non zero digit then previous digit is increased by 1.

Here, the digits to be droped are 5 and 4 after 0.02 so we increase 2 by 1 that is 3.

X =
Exterior Angle =
3x + 25°
20°
X + 550

Answers

Answer:

x=65°  

Step-by-step explanation:

Since all exterior angles add up to 360°.

⇒(3x+25°) + (20°) + (x+55°) =360°

⇒4x+100°=360°                                      {Add up like terms}

⇒4x=260°                                                {Subtract 100 from both sides}

∴  x=65°                                                   {Isolate x (divide both sides by 4)}
