Cho tam giác ABC vuông tại A có cạnh BC=10 AC=8 tính cạnh AB

Answers

Answer 1

Answer:

AB = 6

Step-by-step explanation:

Áp dụng định lý Pytago, ta có:

AB^2 + AC^2 = BC^2

=> AB = [tex]\sqrt{BC^{2}-AC^2 }[/tex]

          [tex]=\sqrt{10^2 - 8^2} \\= \sqrt{100 - 64} \\= \sqrt{36} \\= 6[/tex]

3: 28a-7,

4: 5/8h+7

Step-by-step explanation:

so, a helpful thing with these, is to add like terms. with #4, we see that the letter m is with both of the numbers, and since we are adding a bigger negative to a positive, the answer will be a negative with the number. for 6, 2 numbers have an x, and 2 do not. so we add or subtract the like pairs, as in the ones with the letters, and then a separate one for the one with no letters. for the last one, you always want to have a "common denominator" which is the number on the bottom. because 8 is already on the bottom, and 4 is divisible by 8 by 2, we inversely multiply the top and bottom numbers for the "3/4" and would get "6/8" to match the bottom denominator for "1/8" hope this helps

If the cost, C(x), for manufacturing x units of a certain product is given by C(x)=x2−19x+50 find the number of units manufactured at a cost of $8150

Answers

Answer:

Step-by-step explanation:

C(x) = ax2 + bx + c

C(x) = x2  -19x + 50

8150 = x2  -19x + 50

x2  -19x + 50 = 8150

x2 -19x-8100 = 0

this is a quadratic equation, solved as

x = −b ± √(b2 − 4ac) 2a ·

or

x = −(-19) ± √((-19)x(-19) − 4(1) x(-8100))/2 ·

x= 19± √((-19)x(-19) − 4(1) x(-8100))/2

x = 100

-x-2y=8 slope intercept form please

Answers

Answer:

Add x to both sides so the problem will become -2y =8+x, then you divide both sides by -2 to get y by itself. You will now have y=-4+-x. you'll need to double check this but it should be right. remember that slope intercept form is y=mx + b

√(112) - √(80) / √(20) - √(28) = ?​

Answers

[tex]\large\underline{\sf{Solution-}}[/tex]

We need to solve,

[tex]\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}[/tex]

We can write the above mentioned expression as,

[tex]\sf\longmapsto\dfrac{\sqrt{2\times2\times2\times2\times7}-\sqrt{2\times2\times2\times5}}{\sqrt{2\times2\times5}-\sqrt{2\times2\times7}}[/tex]

So,

[tex]\sf\longmapsto\dfrac{\sqrt{4\times4\times7}-\sqrt{4\times4\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}[/tex]

So,

[tex]\sf\longmapsto\dfrac{\sqrt{4^2\times7}-\sqrt{4^2\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}[/tex]

Hence,

[tex]\sf\longmapsto\dfrac{4\sqrt{7}-4\sqrt{5}}{2\sqrt{5}-2\sqrt{7}}[/tex]

Taking common in respective terms,

[tex]\sf\longmapsto\dfrac{4(\sqrt{7}-\sqrt{5})}{2(\sqrt{5}-\sqrt{7})}[/tex]

On cancelling 4 with 2,

[tex]\sf\longmapsto\dfrac{4\!\!\!/^{\:2}(\sqrt{7}-\sqrt{5})}{2\!\!\!/(\sqrt{5}-\sqrt{7})}[/tex]

[tex]\sf\longmapsto\dfrac{2(\sqrt{7}-\sqrt{5})}{(\sqrt{5}-\sqrt{7})}[/tex]

Taking (-) common,

[tex]\sf\longmapsto\dfrac{-2(\sqrt{5}-\sqrt{7})}{(\sqrt{5}-\sqrt{7})}[/tex]

So, (√5 - √7) gets cut,

Hence,

[tex]\longmapsto\bf\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}=-2[/tex]

In a certain Algebra 2 class of 29 students, 8 of them play basketball and 16 of them play baseball. There are 11 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?

Answers

Answer:

18/29

Step-by-step explanation:

The probability that a student chosen randomly from the class plays basketball or baseball is 18/29

How to determine the probability?

The given parameters are:

Students = 29Basketball = 8Baseball = 16Neither = 11

The number of students that play basketball or baseball is:

Basketball or Baseball = Students - Neither

This gives

Basketball or Baseball = 29 - 11

Basketball or Baseball = 18

The probabilty is then calculated as:

P = Basketball or Baseball/Students

This gives

P = 18/29

Hence, the probability that a student chosen randomly from the class plays basketball or baseball is 18/29
