Step-by-step explanation:

You can test if a triangle is right-angled by using Pythagoras' Theorem.

So:

[tex]4^2 + 7.5^2 = 8.5^2[/tex]

16 + 56.25 = 72.25

They do in fact add up so this triangle is right angled.

Answer: x=2, y=-1

Step-by-step explanation:

Step 1) Make both equations have the same coefficient

What I mean by this is make either y or x have the same number multiplied to them so that we can eliminate. We can do this by multiplying everything in the first equation by 2.

[tex](2)x - (2)2y = (2)4\\2x-4y=8[/tex]

Step 2) Add the equations together to eliminate y

[tex]2x - 4y = 8\\+3x + 4y = 2\\5x+0=10\\5x=10[/tex]

Step 3) Solve for x

[tex]\frac{5x}{5} =\frac{10}{5} \\x=2[/tex]

Step 4) Sub the value of x into an equation and solve for y

[tex]x-2y=4\\2-2y=4\\2-2-2y=4-2\\-2y=2\\\frac{-2y}{-2} =\frac{2}{-2} \\y=-1[/tex]

Answer:

BC = 4.5 (1 dp)

Step-by-step explanation:

Pythagoras’ Theorem

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

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

Substituting these into the formula and solving for BC:

[tex]\implies 1.5^2+4.2^2=BC^2[/tex]

[tex]\implies 2.25+17.64=BC^2[/tex]

[tex]\implies BC^2=19.89[/tex]

[tex]\implies BC=\pm\sqrt{19.89}[/tex]

As distance is positive,

⇒ BC = 4.5 (1 dp)

let us first start with some basic information ~

A fraction can be represented as [tex]\frac{x}{y}\\[/tex] where ,

x is the numerator and y is the denominator !

the question asks us to do something that will help us get same denominator for both the terms !

so let's see what we should do in such a case ~

[tex] \frac{9}{10} \: and \: \frac{7}{8} \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\ \\ \bold\orange{ \implies \: \frac{9}{10} \times \frac{8}{8} = }\bold\red{ \frac{72}{80}} \\ \\\bold\orange{ \implies \: \frac{7}{8} \times \frac{10}{10} =}\bold\red{ \frac{70}{80}} [/tex]

and we're done !

let's add some more info to be lil more clear ~

while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !

The answer would be $14 a sweater.
And S=42*3 (If * is a divide by sign)

Step-by-step explanation:

Step 1. Find the equation. If $42 is total then we know to to divide that number by three getting the equation S=42*3.
Step 2. Do the math. 42 divided by 3 is 14, meaning 14 dollars per sweater.

The hypotenuse is equal to the square of the other two sides. The length of AC from the diagram is 21.9feet

The theorem states that the square of the hypotenuse is equal to the square of the other two sides

Given the following

Hypotenuse = 26 feet = CD
Base side = AD = 14ft

Required

Length AC

Use the theorem

26^2 = 14^2 + AC^2

AC^2 =  676 - 196
AC^2 = 480
AC = 21.9feet

Hence the length of AC from the diagram is 21.9feet

Answer:190 mg of sodium in 1 oz of chips and 40 mg for 1 cup soda.

Step-by-step explanation:

Step-by-step explanation:

the law of sine

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and associated angles are always opposite to each other.

and the sum of all angles in a triangle are always 180°.

sin(90) = 1.

4.

there are multiple solutions, as the direction they are going has no relevance to their position to each other right now.

and the angles of depression can be forward or backwards of the plane.

the larger the angle of depression, the closer the ship is.

for the closer ship we get

height/sin(35) = ground distance / sin(180-90-35)

265/sin(35) = ground distance / sin(55)

ground distance (plane to closer ship) =

= 265×sin(55)/sin(35) = 378.4592218... m

for the farther ship we get

height/sin(25) = ground distance / sin(180-90-25)

265/sin(25) = ground distance / sin(65)

ground distance (plane to closer ship) =

= 265×sin(65)/sin(25) = 568.2943339... m

the distance of both ships is

568.2943339... - 378.4592218... = 189.8351121... m

now, this distance applies to the case, where both ships are on the same side of the plane.

if they are on different sides of the plane, then we need to add their individual distances from the plane to get the distance of both ships from each other :

568.2943339... + 378.4592218... = 946.7535557... m

5.

another right-angled triangle.

the string is the Hypotenuse (baseline).

the height and the ground distance are the legs.

so, we get

100/sin(90) = height/sin(52) = 100

= ground distance / sin(180-90-52)

height = 100×sin(52) = 78.80107536... m

ground distance = 100×sin(38) = 61.56614753... m

Distance formula: distance = sqrt((x2-x1)^2 + (y2-y1)^2)

distance = sqrt((-2 - -9)^2 + (-2 - -6)^2)

Distance = sqrt( 7^2 + 4^2)

Distance = sqrt(49+ 16)

Distance = sqrt(65)

Answer is c. Sqrt(65)

Answer: the answer is c which square root 65

The true statements for the parabola in the image are:

Mathematically, the standard equation of the directrix lines for a parabola is given by y = a(x - h)² + 2.

Given the following data:

Vertex (h, k) = (4, 3).

Point (x, y) = (8, 6).

Next, we would determine the distance where point (8, 6) lies on the parabola:

y = a(x - h)² + 2

6 = a(8 - 4)² + 2

6 = a(4)² + 2

6 = 16a + 2

16a = 6 - 2

16a = 4

a = 4/16

a = 1/4.

Therefore, the equation becomes:

y = 1/4(x - 4)² + 2

When x = 2, we have:

y = 1/4(2 - 4)² + 2

y = 1/4(-2)² + 2

y = 1/4(4) + 2

y = 1 + 2

y = 3.

In conlusion, the true statements regarding the parabola in the image are:
