Answer:

sinA = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]

Step-by-step explanation:

Given

tanA = - [tex]\frac{\sqrt{5} }{1}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with opposite = [tex]\sqrt{5}[/tex], adjacent = 1 and

hypotenuse h² = ([tex]\sqrt{5}[/tex] )² + 1² = 5 + 1 = 6 ⇒ h = [tex]\sqrt{6}[/tex]

Since tanA < 0 and cosA > 0 then A is in the 4th quadrant where sinA < 0

Then

sinA = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]

Answer:

$(19x + 42n + 15)

Step-by-step explanation:

Devi bought 7 skirts at $x each, n skirts at $12 each, (2n + 1) skirts at $15 each and 4 skirts at $3x each. Find the total cost of the skirts she bought.​

total cost of the skirt bought can be determined by adding the  total costs of each shirt bought

7 skirts at $x each = $7x

n skirts at $12 each = $12n

(2n + 1) skirts at $15 = (2n + 1) x 15 = 30n + 15

4 skirts at $3x each = $12x

7x + 12n + 30n + 15 + 12x

combine like terms

19x + 42n + 15

Answer:

A≈842.53

:))))

Volume = side³

=> 1664 = side³

=> ³√1664 = side

=> 4 (³√26) = side

=> 4 (26^1/3) = side

Surface area = 6 side²

=> Surface area = 6 × [4 (26^1/3)]²

=> Surface area = 6 × 140.42 [approximately]

=> Surface area = 842.54 [approximately]

Answer:

190 square inches

Step-by-step explanation:

Surface area of a rectangular prism formula is given as

2(LW + LH + WH)

Where

L = Length = 5in

H = Height = 3in

W = Width = 10in

Hence:

Surface area = 2(5 × 10 + 5 × 3 + 3 × 10) square inches

= 2 × (50 + 15 + 30) square inches

= 2 × (95) square inches

= 190 square inches

Therefore, the surface area of Erin's jewelry box is 190 square inches

Answer:

P(-5,-3)

Step-by-step explanation:

directed line segment  AB where

A(-10,-5) and B(5,1)

Vector of segment AB = B-A = <15,6>

Add one third of the vector length to A to get the partition point, P

A(-10,-5) + <15,6>/3 =A(-10,-5)+<5,2> = P(-5,-3)

edge 2022

Answer:

3. would be one above the negative 5

4. 3 up from positive 4

5. would be on the negative 2

write the letters on those points respectively.

Step-by-step explanation:

y=-2x+2+x+1

y=_2x+x+2+1

y=x+3

The coordinate of the point  on the directed line segment that partitions the segment into a ratio of 4 to 3 is (29/7,50/7)

The given parameters are:

A = (-1,6)

B = (8,8)

Ratio, m : n = 4 : 3

The coordinate at the partition is calculated using:

[tex](x,y) = \frac{1}{m + n} * (mx_2 + nx_1,my_2 + ny_1)[/tex]

So, we have:

[tex](x,y) = \frac{1}{4 + 3} * (4 * 8 + 3 * -1,4 *8 + 3 * 6)[/tex]

Evaluate

[tex](x,y) = \frac{1}{7} * (29,50)[/tex]

Evaluate the product

(x,y) = (29/7,50/7)

Hence, the coordinate of the point is (29/7,50/7)

d. convex hexagon

Step-by-step explanation:

i got a 100 edge 2021

The type of Polygon shown as given in the question with its' shape is called; Convex Hexagon

We are told that the polygon has 6 sides and that no angle goes inside the shape.

Now, a polygon with 6 sides is called a hexagon. However, in this case the name will be a convex hexagon because it will have a hexagonal shape with no interior angle greater than 180°.

Despite that said, regular hexagons will always be called convex hexagon while Irregular hexagons can also be called convex hexagons.

Answer:

Step-by-step explanation:

[tex]h(t)=-16t^2+v_0t+h_0[/tex] where

h(t) is the height of the ball after a certain amount of time has gone by,

-16t² is the pull of gravity in ft/s/s,

v₀t is the initial upwards velocity, and

h₀ is the height from which the ball was initially thrown. Our equation is then, filling in the info in the correct places:

[tex]h(t)=-16t^2+128t+4[/tex] where 128 is the given initial velocity and 4 is the number of feet from which the ball was initially launched.

Answer:

24 sq. m

Step-by-step explanation:

Area of the grass part = area of the park - area of sand area

Park:

l = 6 m  ; w = 5 m

Area of park = l * w = 6*5 = 30 sq.m

Sand :

l = 3 m ; w = 2 m

Area of sand part = 3*2 = 6 sq.m

Area of grass part = 30 - 6 = 24 sq.m

Answer:

24 square meters is the area of the grass part.

Step-by-step explanation:

Multiply both sides of the "sand" section, which are 2 and 3. You get 6.

Now multiply two numbers, 5 and 6, to find the square meters of the whole area, including grass and sand, you get 30.

Now since you only need the area of the grass area, you subtract the area of the sand area, which is 6 sq meters, from the whole area, 30 sq meters, leaving you with 24 square meters as the answer.
