Answer:

h(5.5) = 2550

Step-by-step explanation:

when something is put inside of the parenthesis in a function like h(x) or f(x), it goes where the x is so the equation would look like this

900 + 300(5.5), 900 + 1650 = 2550

Answer with Step-by-step explanation:

10% of 840 can be found by multiplying 840 by 0.10 (or dividing 840 by 10)

10% of 840 = 84

To make a profit of 84 he needs to sell at 840 + 84 = 924 rs

5% of 840 can be found by multiplying 840 by 0.05 (or dividing 840 by 20)

5% of 840 = 42

To make a loss of 42 he needs to sell at 840 - 42 = 798 rs

Make the coefficients of one variable opposites. ...

Add the equations resulting from Step 2 to eliminate one variable.

Solve for the remaining variable.

Substitute the solution from Step 4 into one of the original equations.

Angle 1=87°

Angle 2=88°

angle 1+2= 177

Step-by-step explanation:

I believe thsi should be right,

So angle 1 and 87° are the same because of some rule, then the angle above 2 would be 92 because of the same rule and its a straight line so 180-92=88 making angle 2, 88. When you add those it would be 177. Try that

Answer:

True

Step-by-step explanation:

(-1,4) = (x,y)

This means if "x = -1, then y should be 4"

y = 3x + 7

y = 3(-1) + 7

y = -3 + 7

y = 4

It is saying if x is -1, y is 4. This statement of "Is (-1,4) a solution to the graph of "y = 3x + 7?" Is true. You can also graph this and find the point (-1,4) and it would be on the line.

:D Hope it Helps (I dunno why I put it on this answer box now)

Answer:

Yes.

Step-by-step explanation:

Note that the point:

(x , y) = (-1 , 4)

x = -1

y = 4

Plug in the corresponding numbers for the corresponding variables in the given equation:

y = 3x + 7

(4) = 3(-1) + 7

Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis, Exponent (& Roots), Multiplication, Division, Addition, Subtraction.

First, multiply 3 with -1:

4 = (3 * -1) + 7

4 = -3 + 7

Next, simplify by adding -3 with 7:

4 = (-3 + 7)

4 = 4

Yes. (-1 , 4) is a solution for y = 3x + 7, as the two sides of the equation equal.

Answer:

The slope-intercept form is y=x-5

The graph is in the picture below

Step-by-step explanation:

To find the slope-intercept you need to move y all by itself:

y=mx+b

subtract 3x on both sides:

-3y=-3x+15

Divide by -3 on both sides:

y=x-5

Hope this helps!

(Why I took two pictures is because to show you that the line is the same even with it being slop-intercept form)

Answer:

The correct answer is C [tex]3\frac{8}{33}[/tex]

Solution by separating the parts:

[tex]3\frac{8}{33}[/tex] = 3 + [tex]\frac{8}{33}[/tex]

We know that [tex]\frac{8}{33}[/tex] is 8 ÷ 33.

Therefore: [tex]3\frac{8}{33}=[/tex] 3 + (8 ÷ 33)

You then would have to use "Long Division" for 8 divided by 33

= 3 + 0.242 = 3.242424242424...

Hence giving you 3.24 repeated which is C

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

The geometric representation of this question is based on the Pythagorean theorem:

l² = x² + y²     (1)

Where:

The rate of change of the length of the string is obtained by differential calculus:

[tex]2 \cdot l \cdot \dot l = 2\cdot x \cdot \dot x[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{l}[/tex]

[tex]\dot l = \frac{x\cdot \dot x}{\sqrt{x^{2}+y^{2}}}[/tex]    (2)

If we know that x = 150 ft, y = 90 ft and [tex]\dot x = 30\,\frac{ft}{s}[/tex], then the rate of change of the length of the string is:

[tex]\dot l = \frac{(150\,ft) \cdot \left(30 \,\frac{ft}{s} \right)}{\sqrt{(150\,ft)^{2}+(90\,ft)^{2}}}[/tex]

[tex]\dot l \approx 25.725\,\frac{ft}{s}[/tex]

By Pythagorean theorem and differential calculus, the child must let out the string when the kite is 150 feet away at a rate of change of 25.725 feet per second.

Answer:

Jason multiplied 1.5 by the whole number 10.

Step-by-step explanation:

As opposed to multiplying 1.5 by the tenth power, in which Jason would've received 57.66503..., he multiplied 1.5 by 10 units, resulting in a product of 150.

Hope this helps!

The power of ten did he multiply by 2.

Given that;

Jason multiplied 1.5 by a power of ten and got 150.

Let us assume that;

The value of power = x

Hence it can be written as,

1.5 × 10ˣ = 150

Divide both sides by 1.5;

10ˣ = 150/1.5

10ˣ = 100

It can be written as,

10ˣ = 10²

This gives,

x = 2

Therefore, the value of power is 2.

Answer:9.25

Step-by-step explanation:

The equation of the cell phone plan is y = 70 + 4x and the number of gigabyte is 1.10

The given parameters are:

Flat = $70 per month

Rate = $4 per gigabyte

Let the number of gigabyte be x, and the total cost be y.

So, we have:

y = Flat + Rate * x

So, we have:

y = 70 + 4x

When the bill is $74.40, we have:

74.40 = 70 + 4x

Subtract 70 from both sides

4x = 4.40

Divide both sides by 4

x = 1.10

Hence, the equation is y = 70 + 4x and the number of gigabyte is 1.10

Step-by-step explanation:

n ⇒ number of months it will take for both accounts to have the same amount of money

∴ the equation should be: 250.5 - 35 m = 300 - 45.25 m

⇒ 250.5 - 300 = -45.25m + 35m

Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:

P = Principal / initial amount

R = rate of interest per cent per year

T = number of years

A = final amount at the end of T years

Then:

A = P*(1 + R/100)^2

In our example:

P = £12000

R = 1.5 per cent per year

T = 2 years

Thus:

A = 12000*(1 + 1.5/100)^2

  = 12000*(1 + 0.015)^2

  = 12000*(1.015)^2

   = 12000*(1.030225)

   = 12362.7

Value of investment after two years = £12362.7
