The area of the triangle below is 38.28 square meters. What is the length of the base?

Answers

Answer:

8.8 m

Step-by-step explanation:

Area of triangle = [tex]\frac{1}{2} bh[/tex]

38.28 = [tex]\frac{1}{2}[/tex] * b * 8.7

b = 38.28 * 2 / 8.7

b = 8.8 m

Answer:

m*   =   d**

1   =   $80

2   =   $160

3   =   $240

4 = $320

*months

**Dollars ($)

Step-by-step explanation:

If it costs 80 per month then you times 80 by the number of months you want to work out. For example, you want to work out the cost of going to karate class for 3 months, and it costs $80 per month. Then you do $80 × 3 = $240.

1.) y=2

2.) y=4

3.) y=4

4.) y=-2

Step-by-step explanation:

1.) y=2x Multiply 1*2. y=2

2.) do the same thing. 2*2. y=4.

3.) plug in the x value and do order of operations. y= 2(-4)-4. y=4.

4.) plug in your values again. y= -2(-3)-4. y= -2.

The grade seven students are showing a movie in their school auditorium to raise money for the end of year field trip. Goal is to raise at least $500. Each ticket sales for $16. So far they have sold 20 tickets. Which inequality graph correctly shows how many more tickets they need to sell to reach their goal.

Answers

Answer:

The answer is A because it needs to be a filled dot to represent the information correctly. 16 x 20 is 320 so they need 180 more to have at least 500 dollars which is 11.25 tickets but you cant have a fourth of a ticket so you need atleast 12 tickets sold.

NOT the first one cause 8 isn't the total. Don't think it would be the last one cause that's no fun. So it's either the second or the third one. The third one also makes no sense cause it only includes the returns from yesterday. I'm going with the second one

Where are the minimum and maximum values for f(x)=−2+4cosx on the interval [0,2π]?

Answers

Answer:

[tex]f(x) = - 2 + 4 \cos(x) \\ for \: minimum \: \: x = 0 \\ f(0) = - 2 + 4 \cos(0) \\ minimum \: value = 2 \\ for \: maximum \: value \: \: x = 2\pi \\ f(2\pi) = - 2 + 4 \cos(2\pi) \\ maximum \: value = - 2[/tex]

The function is minimum at 3π/2 and the function is maximum at 0 and 2π.

What is the maximum and minimum value of the function?

The condition for the maximum will be

f(x)'' < 0

The condition for the minimum will be

f(x)'' > 0

The function is given below.

f(x) = −2 + 4cosx

Differentiate the function with respect to x, then we have

f'(x) = − 4 sin x

Again differentiate the function with respect to x, then we have

f''(x) = − 4 cos x

Then the minimum value of the function will be

f'(x) = 0

−4 sin x = 0

sin x = 0

The value of f''(x) is positive in the interval of (π/2, 3π/2). Then the value of x will be

x = π

Then the maximum value of the function will be

And the of f''(x) is negative in the interval of [0,2π] – (π/2, 3π/2). Then the value of x will be

x = 0 and 2π

More about the maximum and minimum value of the function link is given below.

Quadrilateral ABCD is similar to quadrilateral EFGH. Find the measure of side EF

Answers

Answer:

EF = 6.6

Step-by-step explanation:

Since ABCD is similar to EFGH, then EH is similar to AD. So, we can solve by first dividing 12 by 2 (EH by AD). The quotient of this is 6. This tells us that quadrilateral EFGH is 6 times larger than quadrilateral ABCD, since they are similar. So, with this and the measurement of AB (which is similar to EF), we can now solve for EF. We simply multiply 1.1 (the measurement of AB) by 6 (how many times larger EFGH is compared to ABCD). The product of this is 6.6, our final answer.

The list price of an item is $550 and it is chain discount by 50%
less 10% less 20%. How much is the discount?
$352
$198
$440
$110

Answers

Answer:

$352

Step-by-step explanation:

first discount = 550 : 2 = $275

Second discount:

10 : 100 = x : 275

x = (2750/100) = $27,50

275 - 27,50 = $247,50

third discount

20 : 100 = x: 247,50

x = (247.50*20)/100 = $49,50

247,50 - 49,50 = $198 (final price)

total discount = 550 - 198 = $352

Substitute value of y in first equation (3x+4) with y of second equation.

2x-4(3x+4)=-6

-10x=10x=-1

solve for y but putting -1 for x value in either equation

y=3(-1)+4

ASAPPP! An arrow is shot into the air. A function representing the relationship between the number of
seconds it is in the air, t, and the height of the arrow in feet, h, is given by the equation below.
What is the initial height of the arrow?
h(t) = -16t^2+ 128t + 1.5

Answers

Answer:

The initial height of the arrow is 1.5 feet above the ground.

Step-by-step explanation:

Let be the height of the arrow be represented by the function [tex]h(t) = -16\cdot t^{2}+128\cdot t + 1.5[/tex], where [tex]h(t)[/tex] is the current height of the arrow, measured in feet, and [tex]t[/tex], is the time, measured in seconds.

Mathematically speaking, the initial height is the value of [tex]h[/tex] evaluated at [tex]t = 0\,s[/tex]. That is:

[tex]h(0) = -16\cdot (0)^{2}+128\cdot (0) + 1.5[/tex]

[tex]h(0) = 1.5\,ft[/tex]

The initial height of the arrow is 1.5 feet above the ground.

The image is blur and the texts are unreadable. However, the following explanation will assist you

To determine a pair of complementary angles, then both angles must add up to 90.

For instance: 50 and 40; 72 and 18, 10 and 80 etc.

So, all you need to do is select all pairs of angles that add up to 90 in the given image.

Take for instance:

[tex]\angle ABC = 50[/tex] and [tex]\angle BDE = 40[/tex] -- assumed values

This means that, you will select [tex]\angle ABC\ \&\ \angle BDE[/tex] as a pair
