Answers

Answer 1

Answer:

A

Step-by-step explanation:

We know that this is the same as substituting a for x and multiplying the entire expression by -1.

[tex]f(a) = \frac{2a}{a - 1} [/tex]

[tex] - f(a) = \frac{ - 2a}{a + 1} [/tex]

Antonio has 2 2/3 of a piece of wood that he wants to cut into 4 pieces. How long should he cut each piece?
A 8 2/3
B 10 2/3
C 8/3
D 2/3

Answers

Answer:

D 2/3

explanation:

[tex]\bold{total \ length \ \div \ number \ of \ pieces }[/tex]

solve

[tex]\sf 2\dfrac{2}{3} \div 4[/tex]

reciprocal to change signs

[tex]\sf \dfrac{8}{3} \ * \ \dfrac{1}{4}[/tex]

simplify

[tex]\sf \dfrac{2}{3}[/tex]

Solution:

To find the measure of each piece, divide the total piece of wood (2 2/3) by the number of pieces Antonio wants to cut (4).

From the following, we obtained:

[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]

Convert 2 2/3 into an improper fraction:

[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]

[tex]\rightarrow \dfrac{2 \times 3 + 2}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{6 + 2}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]

Simplifying the expression:

[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{8}{3} \times \dfrac{1}{4} \\[/tex]

[tex]\rightarrow \dfrac{8}{3 \times 4}[/tex]

[tex]\rightarrow \dfrac{8}{12} = \boxed{\dfrac{2}{3}}[/tex]

Thus, Antonio should cut 2/3 of wood for each piece.

50l
. Which
of the following is an equivalent form of the expression for the amount remaining in shipment 2?

Answers

The equivalent expression for the amount remaining is an expression that has equal value

The equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

How to determine the equivalent expression

The initial equation of the function is:

[tex]f(t)=50(\frac12)^{\frac t{10}}[/tex]

The function after the scientist receives the second shipment after two days is:

[tex]f(t)=50(\frac12)^{t - \frac 2{10}}[/tex]

Simplify

[tex]f(t)=50(\frac12)^{t - \frac 1{5}}[/tex]

Take the LCM of the exponent

[tex]f(t)=50(\frac12)^{\frac{5t- 1}{5}}[/tex]

Express the exponent as a product expression

[tex]f(t)=50(\frac12)^{\frac{1}{5} * [5t- 1]}[/tex]

Rewrite as:

[tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

Hence, the equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

If usual price for flight is $315.00, the airline is offering a 40% discount until the end of the month. then the cost of the flight after the discount is 126.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that an airline is trying to promote its new Boston to Atlanta flight.

the usual price for this flight is $315.00.

The discount offered by airlines is 40%.

We need to find the cost of the flight after the discount.

Convert 40% to decimal by dividing with 100.

40/100=0.4

Now multiply 0.4 with 315

0.4×315

Zero point four times of three hundred and fifteen.

126

Hence, the cost of the flight after the discount is 126.

PLEASE HELP IM CONFUSED HOW TO FACTORISE THESE

Answers

Answer:

These are all quadratics, where the x/y/a/b coefficient has been cancelled out. So it's like factorising a quadratic. What i mean by the x/y/a/b coefficient being cancelled out is for example y^2 - 1, becomes (y - 1)(y + 1). This is equal to y^2 - y + y - 1. You can see that - y + y = 0, to therefore it's not visible in the final equation, but it's there.

c) y^2 - 1 = (y - 1)(y + 1)

d) x^2 - 64 = (x - 8)(x + 8)

g) a^2 - 81 = (a - 9)(a + 9)

h) x^2 - y^2 = (x - y)(x + y)

k) 25 - x^2 = (5 - x)(5 + x)

l) 1 - b^2 = (1 - b)(1 + b)

o) x^2 - 400 = (x - 20)(x + 20)

p) 900 - y^2 = (30 - y)(30 + y)

I hope this makes sense :))
