plz give me the brainliest

Answer:

height = 6 cm

Base  = 10 cm

Step-by-step explanation:

Let height  = h cm

Base           = h + 4

Area of triangle  = 30 cm²

       [tex]\frac{1}{2}bh = 30\\\\\frac{1}{2}*( h + 4) *h = 30\\[/tex]

Multiply the equation by 2

(h + 4) * h = 30*2

h*h + 4*h = 60

h² + 4h = 60

h² + 4h - 60 = 0

Product = -60

Sum  = 4

Factors = 10, (-6)

h² + 10h - 6h - 6 * 10 = 0

h(h + 10) - 6(h + 10) = 0

(h +10)(h - 6) = 0

{Ignore h + 10 = 0 because measurements will not be in negative}

h - 6 = 0

    h = 6 cm

    b = 6 + 4 = 10 cm

The Graph Shifts 4 units up

Step-by-step explanation:

Okay so, when you add four to a graph in this manner we have to look at the equation as a whole. f(x)=mx+b + 4. By adding four we are changing the y-intercept and shifting it up four. This will cause the entire graph to shift upwards four spaces.

Answer:

The value of x is 37.36

Step-by-step explanation:

The given triangle is a right-angled triangle where

Base = 25

Angle = 48°

Hypotenuse = x

As the triangle is a right angled triangle, trigonometric ratios can be used to find the missing value. We can use a ratio which uses base and hypotenuse.

[tex]cos\ 48 = \frac{base}{hypotenuse}\\cos\ 48 = \frac{25}{x}\\0.6691 = \frac{25}{x}\\x = \frac{25}{0.6691}\\x = 37.36[/tex]

Hence ,

The value of x is 37.36

I checked on RSM system

Answer:

90min

Step-by-step explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

[tex]x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours[/tex]

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours [tex]\frac{60min}{1 hours}[/tex]

1.5 hours =(1.5)(60) min

1,.5 hours =90min

Answer:

Shorter leg=3

Longer leg=4

Step-by-step explanation:

Equations

In a right triangle, Pythagora's Theorem is satisfied. Being a the hypotenuse, b and c the legs of the triangle, then:

[tex]a^2=b^2+c^2[/tex]

Let's call

x=the shorter leg of the triangle

The longer leg is 1 cm longer than the shorter leg, thus:

x+1=the longer leg.

Since the hypotenuse is 5 cm long:

[tex]5^2=x^2+(x+1)^2[/tex]

Operating:

[tex]25=x^2+x^2+2x+1[/tex]

Swapping sides and simplifying:

[tex]2x^2+2x+1=25[/tex]

Subtracting 25:

[tex]2x^2+2x-24=0[/tex]

Dividing by 2:

[tex]x^2+x-12=0[/tex]

Factoring:

[tex](x-3)(x-4)=0[/tex]

We have two possible solutions:

x=3, x=4

The longer leg is x+1.

If x=3, x+1=4

If x=4, x+1=5. This solution is not valid because one leg would be equal to the hypotenuse.

Thus, the solution is:

Shorter leg=3

Longer leg=4

Answer:

I would say get a small ruler thing and measure them off your screen and say (*Measure off my screen*), then say the distance the dots are from the center point is the same because those dots, when connected to the center point, makes the radius, and the radius stays the same around the circle.

Answer:

1330.56

Step-by-step explanation:

96 percent of 1386 is 1330.56

Answer:

Step-by-step explanation:

The question gives you numbers that you don't need to answer the question.

Salt water = 96/100 * 1,386 * 10^6 million km = 0.96 * 1386 * 10^6 = 1330560000 = 1.33056 * 10^9

You can find the fresh water amount by subtracting from 1385 * 10^6  which gives 1386 * 10^6 - 1.33056 * 10^9 = 55 440 000 cubic km

Answer:

(- 2x , - 2y)

Step-by-step explanation:

A(x, y) ----> A' (kx, ky)

~~~~~~~~

H(- 1 ,1) ----> [k(- 1), k(1)] ----> G(2, - 2) ⇒ k = - 2

M( - 1.5, - 4) -----> [(- 2)(- 1.5) , (- 2)(- 4)] ------> R(3. 8)

k = - 2

Thus, the rule of dilation centered in origin is (- 2x , - 2y)

Answer:

Min value of F = 24

It happens when m = 3 and a = 4.

==========================================================

Explanation:

Start with ma = 12 and Solve for 'a'  to get a = 12/m

Plug it into the other equation to get

F = 3a + 4m

F = 3(12/m) + 4m

F = 36/m + 4m

F = 36/m + (4m^2)/m

F = (36+4m^2)/m

The equation above is in the form F = a/b where a = 36+4m^2 and b = m

Applying derivatives to each piece gives a' = 8m and b' = 1

So,

F = a/b

F ' = (a/b)'

F ' = (a' * b - a * b')/(b^2) .... quotient rule

F ' ( 8m*m - (36+4m^2)*1 )/(m^2)

F ' = (8m^2 - 36 - 4m^2)/(m^2)

F ' = (4m^2 - 36)/(m^2)

---------------------

The minimum of F occurs when F ' = 0

F ' = 0

(4m^2 - 36)/(m^2) = 0

4m^2 - 36 = 0*m^2

4m^2 - 36 = 0

4m^2 = 36

m^2 = 36/4

m^2 = 9

m = sqrt(9) or m = -sqrt(9)

m = 3 or m = -3

Keep in mind that m > 0, so we ignore m = -3

---------------------

Next we'll use the first derivative test. I find it's easier compared to the second derivative test because we don't have to do another derivative.

The function F(m) = (36+4m^2)/m has a potential min point at m = 3.

To see if we have an actual min point or not, we need to check the sign of F ' (m) when m = 2 and m = 4; that way we see if F ' (m) changes sign as we pass through m = 3.

First compute the derivative when m = 2

F ' (m) = (4m^2 - 36)/(m^2)

F ' (2) = (4(2)^2 - 36)/(2^2)

F ' (2) = (4*4-36)/(4)

F ' (2) = (16-36)/(4)

F ' (2) = -20/4

F ' (2) = -5

The actual value doesn't matter. All we're after is the sign of it. So we see that F ' (2) is negative which means we know that F(m) is decreasing when 0 < m < 3

Now let's try m = 4

F ' (m) = (4m^2 - 36)/(m^2)

F ' (4) = (4(4)^2 - 36)/(4^2)

F ' (4) = (4*16-36)/(16)

F ' (4) = (64-36)/(16)

F ' (4) = 28/4

F ' (4) = 7

This value is positive, so F(m) is increasing on the interval 0 < m < infinity

F(m) decreases on 0 < m < 3 and increases on  3 < m < infinity

So the F function goes downhill and then goes back uphill, and this lowest valley point is when m = 3

So we've confirmed that F(m) does indeed have a min value at m = 3.

Making a sign chart or interval might help visualize it.

---------------------

Now onto the last part.

Plug m = 3 into F(m) to find the min value of F

F = (36+4m^2)/m

F = (36+4*3^2)/3

F = (36 + 4*9)/3

F = (36 + 36)/3

F = 72/3

F = 24

The smallest F can get is 24 and it happens when m = 3 and a = 12/m = 12/3 = 4.

------------------------------

Side note: A non-calculus approach would have you graphing y = (36+4x^2)/x, and then using the graphing calculator to find the lowest point in the first quadrant. We're in this quadrant since a, m and F are all positive.

Step-by-step explanation:

Answer:

20 tickets each will have to bought with fast pass so that the total cost is equal to that of each other.

Step-by-step explanation:

Entry fee for The Great Adventure theme park = $15

Charge for fast pass at each ride = $1.50

Entry fee for The Big Thicket amusement park = $15

Charge for fast pass at each ride = $1.00

Let the number of ride tickets purchased with Fast pass = [tex]x[/tex]

As per question statement, the total cost at each will be equal to that of each other.

Writing in the equation form, we get:

$15 + $1.50 [tex]\times[/tex] [tex]x[/tex] = $25 + $1.00 [tex]\times[/tex] [tex]x[/tex]

[tex]\Rightarrow 1.50x -1.00x = 25 -15\\\Rightarrow 0.50x = 10\\\Rightarrow x = 20[/tex]

Therefore, 20 tickets each will have to bought with fast pass so that the total cost is equal to that of each other.

Answer:

t=2

Step-by-step explanation:

3t-6=t-2(Group like terms)

3t-t=-2+6

2t=4(Divide both sides by 4)

t=2( This is because when you divide both sides by 2, 2 can divide 4 2 times so that's why we have t as equal to 2)
