Answer:

-772

Step-by-step explanation:

First, multiply the brackets with the numbers before them:

4(-) = -4

-32(22-) = -704-

2(-) = -2

Then put them back into the question

-4 - 62 - 704 - 2

Subtract them to get the answer

-4 - 62 - 704 - 2 = -772

PS: Not sure if it completely correct but it’s worth a try.

The ratio between the vertical angle and a base angle of an isosceles triangle is 4:3,find all the angles of the triangle

koban [17]

Given ratio between the base angle and vertical angle of an isosceles traingle is 2:5

⇒ base angle / vertical angle = 2 / 5

let base angle = x

⇒ verticle angle = (5/2)x

we know that
verticle angle + base angle + base angle = 180°

⇒ ( 5/2 + 1 + 1 ) x = 180°

⇒ (9/2)x = 180°

⇒ x = ( 180° x 2) / 9

⇒ x = 40°

verticle angle = (5/2) x 40° = 100°

Graph f(x)= -(x-2)²+4<img src="https://tex.z-dn.net/?f=" id="TexFormula1" title="" alt="" align="absmiddle" class="latex-formula

Mandarinka [93]

Answer: See the graph attached.

Step-by-step explanation:

The standard form of a quadratic function is:

$f(x)=a(x-h)+k$

Where (h,k) is the vertex of the parabola.

If $a$ is negative, then the parabola opens down.

Then, for the function:

$f(x)=-(x-2)^2+4$

You can identify:

$h=2\\k=4$

Then the vertex of the parabola is at (2,4)

Note that $a=-1$ , therefore the parabola opens down.

Find the intersection with the x-axis. Substitute $f(x)=0$ and solve for x:

$0=-(x-2)^2+4\\0=x^2-4x\\0=x(x-4)\\\\x_1=0\\x_2=4$

Knowing that the vertex is at (2,4), the parabola opens down and it intersects the x-axis at x=0 and x=4, you can graph the function, as you observe in the figure attached.

The MD orders 50mg of an elixir to be given every 12 hours. Available is 125mg/5ml. How much should be administered every 12 hou

Jet001 [13]

FORMULA

D ( desired dose) x V ( vehicle- tablet or liquid)

H ( dose on hand)

D = Dose ordered

H = dose on hand or dose on container label

V = form and amount in which drug comes ( tablet, capsule, liquid)

D= 50mg H= 125mg V= 5ml

50 x 5

125

250 divided by 125 = 2ml

So, 2ml of elixir is administered every 12 hours :) brainliest pls

The cheerleaders are selling tickets to a pasta dinner to raise money for new competition outfits. They plan to charge $6 per pe

kow [346]

Answer:

22 and a half ticket sold here will result in no profit situation for cheerleaders.

Step-by-step explanation:

The charge per person = $6

The total cost for dinner = $135

If cheerleaders do not make any profit , then

{ If the money earned from tickets = The money Spent} ⇒ NO PROFIT

Now, charge per person = $6

So, number of person needed to earn a total of $135

n = $\frac{\textrm{The total money needed}}{\textrm{Charge per person}}$

n = $\frac{135}{6}$ = 22.5

So, 22 and a half ticket sold here will result in no profit situation for cheerleaders.

If they sell 23 tickets, they will have a profit of $3

And if they sell 22 tickets, they will be short by $3.
