Work out the area of Triangle ABC
Just to confirm, these are the numbers,
Bottom right: √2cm
Bottom Left: 3√2cm
Middle right: 2√5cm
The main idea is using the Pythagorean formula to find the length of line segment [tex]DB[/tex].
Alr so you use the formula [tex]A^2 + B^2 = C^2[/tex]
[tex]C^2[/tex] is already given and is [tex]2\sqrt{5}[/tex]
and [tex]A^2[/tex] is [tex]3\sqrt{2}[/tex]
So using algebraic rules you'll get [tex]B[/tex] as:
[tex]\sqrt{2}[/tex]
Now using the formula: [tex]\frac{1}{2} b * h[/tex], you can find the area of tri ABD and CBD which would be [tex]3[/tex] and [tex]1[/tex] so add them up and you get [tex]4[/tex]!

What is the 50th term of the arithmetic sequence 7, 10, 13, ...?
show complete working format please
Answer:
154
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 10 - 7 = 3 , thus
a₅₀ = 7 + (49 × 3) = 7 + 147 = 154

Consider quadrilateral EFGH.
The slope of EF is .
Which statements are true? Check all that apply.
EH is parallel to FG.
EF is perpendicular to EH.
HG is neither parallel nor perpendicular to FG.
Quadrilateral EFGH is a rectangle because it is a parallelogram with four right angles.
Quadrilateral EFGH is a trapezoid because it has exactly one pair of parallel opposite sides.
(B) EF is perpendicular to EH.
Quadrilateral:A quadrilateral in geometry is a four-sided polygon with four sides and four corners (vertices). The Latin words Quadri, a variation of four, and latus, meaning "side," are the source of the name. In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon). Since "gon" is an anagram for "angle," it is also known as a quadrangle or 4-angle. Display style "square ABCD" is sometimes used to indicate a quadrilateral with the vertices A, B, C, and D.Therefore, the correct option is (B) EF is perpendicular to EH.

The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V. Write the direct variation equation for the scenario above.
Answer:
[tex]D=kV^2[/tex]
Step-by-step explanation:
In this problem, it is given that,
The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.
We need to write the direct variation equation for the scenario above. It can be given by :
[tex]D\propto V^2[/tex]
To remove the constant of proportionality, we put k.
[tex]D=kV^2[/tex]
k is any constant
Hence, this is the required solution.

y=-5x+4
(0,4)
(1,-1)
Step-by-step explanation:
Answer:
(1,-1)
Step-by-step explanation:
You would graph y=-2x+1 by starting the graph at (0,1) then placing another point at (-1, 3) and drawing a straight line through those points. You would graph y=-5x+4 by starting the graph at (0,4) then placing another point at (-1, 9) and drawing a straight line through those points. The answer would be where the two graphs intersect which is (1,-1).

divide £400 by 5
400/5 = 80
Segment A'B' is parallel to segment AB. What is the length of segment AB? What is the length of segment B'B? Your answer should be in decimal form with only one decimal place.
B’B is 3.5
Step-by-step explanation:
Segment A'B' is parallel to segment AB.
So, The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units
Given :
Segment A'B' is parallel to segment AB. Few sides of the triangle is given.
Apply basic proportionality theorem
When A'B' is parallel to segment AB then sides are proportional
[tex]\frac{CB'}{B'B} =\frac{CA'}{A'A}[/tex]
Substitute the values
[tex]\frac{7}{B'B} =\frac{6}{3} \\cross \; multiply\\7(3)=B'B(6)\\21=B'B(6)\\Divide \; by \; 6\\B'B= \frac{21}{6} \\B'B=3.5[/tex]
Now we find AB by making a proportion
[tex]\frac{CA'}{CA} =\frac{BA'}{BA} \\\frac{6}{9} =\frac{5}{AB} \\Cross \; multiply\\6(AB)=5 \cdot 9\\6AB=45\\Divide \; by \; 6\\AB=7.5[/tex]
The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units

solve the following inequality for w then simplify
-w+9>6w+8
Answer:
[tex]\displaystyle (-\infty,\frac{1}{7})[/tex]
Step-by-step explanation:
Inequalities
To solve the inequality:
[tex]-w+9>6w+8[/tex]
We need to perform the required operations on both sides of the inequality to have the variable w isolated.
First, we subtract 9:
[tex]-w+9>6w+8[/tex]
[tex]-w>6w+8-9[/tex]
Subtracting 6w:
[tex]-w-6w>+8-9[/tex]
Operating:
-7w>-1
Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:
[tex]\displaystyle w<\frac{-1}{-7}[/tex]
Operating:
[tex]\displaystyle w<\frac{1}{7}[/tex]
Solution:
[tex]\mathbf{\displaystyle (-\infty,\frac{1}{7})}[/tex]
A coach travels to the beach which is 576 KM away in 6 hours. If he is only allowed to travel at a maximum speed of 90 kph, did the coach break the speed limit? What was his average speed?
Answer:
Yes
Step-by-step explanation:
576Km:6Hrs
576 divided by 6=96 km
6 divided by 6=1
96km:1hr
96 was the coaches speed limit
km=Kilometers
Hrs=Hours
96>90
yes , the coach break the speed limit and the average speed is 96 km ph
What is Speed?Speed is the time rate at which an object is moving along a path
Given,
A coach travels to the beach which is 576 KM away in 6 hours.
The maximum speed he can travel is speed of 90 kph
We need to check whether the coach breaks the speed limit or not.
Yes he has to break the speed limit because in 6 hours with 90kph he can travel only 540 km. He still needs to travel 36 km.
and the average speed he has to maintain is 576/6
96kmph
Hence, yes the coach break the speed limit and the average speed is 96 km ph
