Answer 2

Answer:

= 222q^8 - 5m + 20n -37 + 21

Step-by-step explanation:

−5(m−4n−5)−37(p−6q8)−4

step 1  

=(−5)(m)+(−5)(−4n)+(−5)(−5)+(−37)(p)+(−37)(−6q8)+−4

=−5m+20n+25+−37p+222q8+−4

step 2

=−5m+20n+25+−37p+222q8+−4

=(222q8)+(−5m)+(20n)+(−37p)+(25+−4)

=222q8+−5m+20n+−37p+21

Without using a calculator order the following numbers from least to greatest

8 √58 7

Answers

Answer:

7, √58, 8

Step-by-step explanation:

7 x 7 = 49

8 X 8 = 64

49, 58, 64

[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Mathematics.

Applying the simple squares of 7 and 8.

7*7= 49 and 8*8=64

hence square root 58 is more than 7 but less than 8

hence we get as,

[tex]7 < \sqrt{58 } < 8[/tex]

Step-by-step explanation:

Question 1: Just substitute in the values of f(x) and g(x) and simplify!

f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6f(x)-g(x) = -x^2-2x-3

pythagorean theorem

take the sum of the square of each leg and set it equal to the square of the hypotenuse

8² + 6² = x²

64 + 36 = x²

x² = 100

x = [tex]\sqrt{100}[/tex] or 10

Answer:

B.10 units

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2

Plug in what we know....

8^2+6^2=c^2

64+36=c^2

c=sqrt(100)

Haley made 88% on a history test. The
test had 50 questions of equal point value.
How many questions did Haley miss?

Answers

Answer:

She missed 6 questions.

Step-by-step explanation:

88% can be written as (88/100) or as 0.88.

You can set this as a ratio problem which is,  

88/100 = correct/50

correct = (88/100)*50       (multiply both sides by 50)

correct = 44

So, 50 (total questions) - 44 = 6 incorrect questions

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.

∴ The horizontal or adjacent distance can be obtained by tan(theta).

Assuming horizontal distance to be x feet.

∴ tan(5°) = 2/x feet.

x = 2/tan(5°).

x = 22.9 feet.
