The triangle gotten from this pattern is an isosceles obtuse triangle.

A pattern is a repeated arrangement of numbers, shapes, colours and other items.

Using the rule, we have two obtuse then one right triangle. Hence the fifth would be an obtuse triangle.

For the second, we have isosceles and scalene changing, hence the fifth would be isosceles.

I did my method that I was taught but if you do (-5) - (-2), you get 3. So you subtract 39 by the -21 to get 18.

Answer:

-52.5

Step-by-step explanation:

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 :))

Answer:

Speed of the boat is 9.4mph and the current is 15.4mph

Step-by-step explanation:

Rate= distance/ time

With current; rate= boat+ current= b+c

Against current; rate= boat - current = b- c

30=3(b+c)••••••••••••••eqn(1)

30=5(b-c)•••••••••••••••••eqn(2)

30=3b +3c••••••••••••••eqn(3)

30=5b-5c•••••••••••••••eqn(4)

Solve simultaneously

b=12mph

From eqn(3)

30=3b +3c

Divide both sides by 3, we have

10= b+c

If we make "b" the subject of the formula we have

b= (10-c)••••••••eqn(5)

Divide both side of eqn(4) by 5 we have

6=b-c••••••••eqn(7)

Substitute eqn(5) into 7

6= (10-c)-c

6= 10c-c^2

C^2-10c+6

C= 9.4 or 0.64

Substitute the highest value 9.4 into equation 7

6=b-9.4

b=6+9.4

b= 15.4

Speed of the boat is 9.4mph and the current is 15.4mph

The only answer possible is 11 if we are talking whole numbers but something with decimals might work as well, I mean 22 only has 2 dividends and that is 11X2 and 22X1

Answer:

NO

Step-by-step explanation:

substitute x=3  into the equation

2(3)+3

=9

Therefore x=3 is not a solution

Answer:

No, it is not a solution.

Step-by-step explanation:

x = 3

8 = 2x + 3

8 = 2 (3) + 3

8 = 6 + 3

8 ≠ 9

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]

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.

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.
