graph the equation.
- 5/4 (x-1)(x+3)
Answer:
Step-by-step explanation:
So, to graph a parabola we must have at least 3 points, the x intercepts and the turning point. Currently the equation is in x intercept form which means that we know straight away (assuming the equation =0) that the x intercepts are:
(1,0) and (-3,0)
Now we have to find the turning point and we can do this by putting the equation into turning point form:
-5/4([tex]x^{2} +2x-3[/tex])
-5/4(([tex](x+1)^{2} -3-1[/tex])
-5/4[tex](x+1)^{2}+5[/tex]
Now we can figure out the turning point which is:
(-1,5)
Graph those three points and you should get a parabola shape

Find the product of (x 5)(x − 5). X2 − 10x 25 x2 10x 25 x2 − 25 x2 25.
Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x+5)(x-5) = x^2 - 25[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is obtained as:
[tex](x+5)(x-5) = x(x - 5) + 5(x - 5) \\\\(x+5)(x-5) = x^{1+1} - 5x + 5x - 25 = x^2 - 25[/tex]
Thus,
The product of [tex](x+5)(x-5) = x^2 - 25[/tex]

Step-by-step explanation:
All you have to do is divide and you do that for all of them. Also did you know quotient means the answer to a division question. Wow! Also, if you see that all I did was add another zero in the middle of the decimals is because That is Decimal Place value. Here is a picture of that just in case. The last answer for the very bottom one is what I just said about decimal place value so here is the reflection: When dividing by tens using decimals always be sure to use place value.

candy had some money. she bought a drink for £1.45 and a piece of cake for £1.20 she now has two thirds of her money left. how much money did candy to start with? i suck at fraction
The amount of money Candy started with after spending on drinks and cakes is £7.95
How to find the amount of money she started with?She bought a drink for £1.45 and a piece of cake for £1.20.
She has two thirds of here money left.
Let the money she has initially = x
Therefore,
2 / 3 x = x - 1.45 - 1.20
2 / 3 x = x - 2.65
subtract x from both sides
2 / 3 x - x = - 2.65
2x - 3x / 3 = - 2.65
- x / 3 = - 2.65
cross multiply
-x = - 2.65 × 3
- x = -7.95
x = £ 7.95
Therefore, Candy started with £7.95

The sides of One World Trade Center in New York City form
eight isosceles triangles, four of which are 200 ft long at their base BC. The
length AC of each sloping side is approximately 1185 ft.
The value of ∠BAC in the isosceles triangle is 9.7°
Cosine rule
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
a² = b² + c² - 2bc*cos(A)
where a, b, c are the sides of the triangle and A, B, C are the angles opposite the sides.
AB = AC = 1185 (isosceles), BC = 200, let ∠BAC = x°, hence:
200² = 1185² + 1185² - 2(1185)(1185)cos(x)
2(1185)(1185)cos(x) = 2808450
cos(x) = 0.9857
x = 9.7°
The value of ∠BAC in the isosceles triangle is 9.7°

Answer:
93
Step-by-step explanation:
The sum of the interior angles of a triangle is 180 degrees. The given measures, 37 and 56, sum up to 93. 180-93 = 87. This means the last interior angle is 87 degrees. But, the degree measure of a straight line is also 180 degrees, so 180-87 is 93, the answer.

7. Arrival of the Normandy Train
Claude is waiting to meet the train from Normandy at Gare Saint-Lazare in Paris. He
tells Marie the hour of the train's arrival and he tells Jean at which minute it arrives. He
also tells them both that the train arrives between 0600 and 1000.
They consult the timetable and find the following services between those times:
0620, 0639, 0650; 0717, 0746; 0825, 0839; 0917, 0925, 0950.
Marie then says, “I don't know when Claude's train arrives, but I'm sure that neither does
Jean."
Jean replies, “I didn't know his train, but now I do."
Marie responds, “Now I do as well!"
When is Claude's train and how do you know?
Answer:
0839
Step-by-step explanation:
First of all, let's cancel 0620 and 0746, because they dont have any other number that has the same last 2 digits as them. Jean would've immediately known the train number if it was one of these two.
Now, when Marie says "I'm sure that neither does Jean", it means she is guaranteed Jean doesn't know the train number. It mean she couldnt've gotten 06 or 07, as 0620 and 0746 have it.
We're left with 0825,0839,0917,0925 and 0950
When Jean replies he knows the train number, it means he couldnt've gotten 25, as it's repeated.
And when Marie responds she knows as well, she couldnt've gotten 09, as it's also repeated.
We can cancel 0825,0917,0925 and 0950
So, the train number is 0839

A. MO/SA = OE/AW
Step-by-step explanation:
A. would be your correct answer because if you analyze the triangles you can see that the similar sides would be MO and SA, OE and AW, and ME and SW. In all of the answers, they compare sides that arent similar like OE/SW. However, in the first answer, the sides they compare are indeed similar, as you can see by what I listed above. These sides are similar because they are both the adjacent and opposite sides of each triangle.

Answer:
b > -3
Step-by-step explanation:
-5(2b+7) + b< -b - 11
Distribute -5
-10b - 35 + b < - b - 11
Combine like terms.
-9b - 35 < - b - 11
Add b to both sides.
-8b - 35 < -11
Add 35 to both sides.
-8b < 24
Divide by -8. REVERSE THE SYMBOL!! because dividing by a negative number.
b > -3

Answer:
15200 cm²
Step-by-step explanation:
from inspection of the diagram, we can see that the prism comprises:
2 congruent triangles1 base rectangle2 congruent side rectanglesTriangle
Area of triangle = 1/2 x base x height
Given:
base = 60 cmheight = 40 cm⇒ area = 1/2 x 60 x 40 = 1200 cm²
Base rectangle
Area of a rectangle = width x length
Given:
width = 60length = 80⇒ area = 60 x 80 = 4800 cm²
Side rectangle
Area of a rectangle = width x length
Given:
width = 50length = 80⇒ area = 50 x 80 = 4000 cm²
Total area = 2 triangles + base rectangle + 2 side rectangles
⇒ total area = (2 x 1200) + 4800 + (2 x 4000) = 15200 cm²
