3. In a certain school, there are 456 girls. Calculate the total number of students

marin [14]

Answer:

3) girls = 24% = 456

let the total number of students be = x

$\frac{24}{100} \times x = 456$

$x = 456 \times \frac{100}{4}$

$x = 1900$

the total number of students is 1900

4) increase = 20%

new salary = 24000 rupees

let his original salary be = y

$\frac{20}{100} \times y = 24000 - y$

$0.2y = 24000 - y$

$0.2y + y = 24000$

$1.2y = 24000$

$y = \frac{24000}{1.2}$

$y = 20000$

his original salary is 20,000 rupees

The slope of the line below is -3. Is the coordinates of the labeled point to find a point - slope equation of the line

puteri [66]

Point slope form = y - b= m ( x - a )

where y and x stay the same

m is the slope

and (a, b) (any coordinate on the graph)

based on the point (5, -7)

Y - (-7) = -3 (x - 5)

however, the - cancels out the negative 7 making I positive

Y + 7 = -3(x - 5)

Given: sin θ = 0.8660 hypotenuse = 0.25 Find: θ = (please explain).

Bad White [126]

Answer:

Given that

sinθ = 0.8660

⇒ sinθ = 0.8660 = √3/2

⇒ θ = sin⁻¹(√3/2)

⇒ θ = 60°

How are the graphs of the functions f(x) = √16^x and g(x) =3√64^x related?

liberstina [14]

Answer:- The functions f(x) and g(x) are equivalent.

Explanation:-

Given functions:- $f(x)=\sqrt{16^x}$ and $g(x)=\sqrt[3]{64^x }$

Simplify the functions by using law of exponents

$(a^n)^m=a^{nm}$

Thus $f(x)=\sqrt{16^x}=\sqrt{(4^2)^x}=\sqrt{4^{2x}} =\sqrt{(4^x)^2}=4^x$

and $g(x)=\sqrt[3]{64^x}=\sqrt[3]{(4^3)^x}= \sqrt[3]{4^{3x}}= \sqrt[3]{(4^x)^3}=4^x$

⇒f(x)=g(x)

Therefore ,the functions f(x) and g(x) are equivalent.

Use polynomial long division to find the quotient and the remainder when 2x^3-3x^2-2x-1 is divided by x-3

Alexxx [7]

Answer:

quotient: 2x^2 +3x +7
remainder: 20

Step-by-step explanation:

See the attachment.

At each step, the value being subtracted from the dividend is the product of the quotient term and the divisor. The quotient term is found by dividing the highest-degree term of the dividend by the highest degree term of the divisor (x).

When the dividend has a degree that is less than the degree of the divisor, we call that value (20) the remainder.
