Write the expression without radicals, using only positive exponents.

Step-by-step explanation:

Given:

Find: Z to two decimal places

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {z}^{2} = {y}^{2} \\ {70}^{2} + {z}^{2} = {106}^{2} \\ 4900 + {z}^{2} = 11236 \\ {z}^{2} = 11236 - 4900 = 6336 \\ z = \sqrt{6336} = 79.60[/tex]

Answer:

3*r = 3

Step-by-step explanation:

[tex]\dfrac{24}{r}=3\\\\24 = r*3\\\\\dfrac{24}{3}=r\\\\6 = r[/tex]6 is a solution.

[tex]3*r=3\\\r =\dfrac{3}{3}\\\\r = 1\\[/tex]

6 is not a solution.

[tex]7r = 42\\\\r =\dfrac{42}{7}\\\\r = 6[/tex]

6 is a solution

Answer:

My best answer is A

Step-by-step explanation:

if you plug in 6 for r, it doesn't work for A.

B is hard to see so can't tell

C works with r=6, so it's not C

and D works as well, so it's not D

Answer:

-94.5

Step-by-step explanation:

7.5 less 102 is equivalent to the negative of 102 less 7.5:  -(102 - 7.5) = -94.5.

It is not strictly necessary to reverse the order of the numbers as shown above, but 102 - 7.5 is more famliar (and thus easier to deal with) than

7.5 - 102.

Answer:

15

Step-by-step explanation:

3 · 2 = 6

2 · 3 = 6

6 + 6 = 12

The quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.

In arithmetic, a quotient is a quantity produced by the division of two numbers.

Given is to find the quotient of 6.591 x 10⁷⁶ and 8.45 x 10².

We have to find the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10².

6.591 x 10⁷⁶ ÷ 8.45 x 10²

(6.591 x 10⁷⁶/8.45 x 10²)

(6.591 x 10⁷⁶ ⁻ ²)

6.591 x 10⁷⁴

Therefore, the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.

Answer:

Side of the cube: 10cm

Step-by-step explanation:

Firstly, I'd like to state that cubes actually do not have a radius, they have sides. Hence, I am going to solve for sides below:

Volume formula for a cube:

v = s³

Since the volume is 994 cm³

s³ = 994

s = [tex]\sqrt[3]{994}[/tex]

= 9.97995986613

≈ 10cm

Answer:

[tex]P(x)=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]

Step-by-step explanation:

Each root corresponds to a linear factor, so we can write:

[tex]P(x)=x^{2} (x-1)^{2} (x+3)\\=x^{2} (x^{2} -2x+1(x+3)\\\\=x^{5} +x^{4} -5x^{3} +3x^{2}[/tex]

Any polynomial with these zeros and at least these multiplicities will be a multiple (scalar or polynomial) of this [tex]P(x)[/tex]

Footnote

Strictly speaking, a value of [tex]x[/tex]  that results in [tex]P(x)=0[/tex] is called a root of  

[tex]P(x)=0[/tex] or a zero of [tex]P(x)[/tex] . So the question should really have spoken about the zeros of [tex]P(x)[/tex]  or about the roots of [tex]P(x)=0[/tex]

Answer:

20% increase

Step-by-step explanation:

the initial number is 110 so lets take that as a 100%

the final number is 132 and it will be x

110/132=100/x

we multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.

110*x=132*100

110x=13200

x=120

Then we deduct 120 by 100 to know how much the percent increase is

(120-100)%=20% :)

Answer:

Answer:

y=-2x+5

Step-by-step explanation:

x-2y=2

2y=x-2

y=(x-2)/2

so the slope is 1/2

for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition

(1/2)m=-1

m=-2

the only line with a slope of -2

Answer6x3-33x2+45x-6

Step-by-step explanation:

The product of polynomials is 6x³-33x²+45x-6. Therefore, option C is the correct answer.

To multiply two polynomials: multiply each term in one polynomial by each term in the other polynomial. Add those answers together, and simplify if needed.

Given that, (3x-6)(2x²-7x+1).

By using distributive property, we get

3x(2x²-7x+1)-6(2x²-7x+1)

= 6x³-21x²+3x-12x²+42x-6

= 6x³-21x²-12x²+3x+42x-6

= 6x³-33x²+45x-6

Therefore, option C is the correct answer.
