Answer:
180 square yards
Step-by-step explanation:
there are 3 shapes that create the total area :
a large right-angled triangle to the right. its baseline is 16 yd. the left side is a bit complicated, we get to it.
a small middle rectangle with length 6 yd. it's width is 3 yd.
is area is 6×3 = 18 yd²
a large rectangle at the bottom left with length 11 yd and width 6yd.
its area is 11×6 = 66 yd²
now, how long is the left side of the triangle ? we need it as the height of the triangle to get the area
baseline × height / 2
we see that a part of the left side is 8 yd.
then the width of the middle rectangle is also a part of that left side : 3 yd.
and then we notice that the triangle goes a little bit below the top length side of the large rectangle. how much ? well the actual width of the large rectangle is 6 yd, but the side under the triangle says only 5 yd. so, the missing piece is 6-5 = 1 yd.
so, the full left side is
8 + 3 + 1 = 12 yd
and the area of the triangle is
16×12 / 2 = 16×6 = 96 yd²
so, the total area of the figure is
18 + 66 + 96 = 180 yd²
Two numbers are in the ratio 3 : 5. if each number is increased by 10, the ratio becomes 5 : 7.The numbers are .
Given 3x and 5x --------------- (i)
(3x+10)/(5x+10) = 5/7
On cross multiplication we get :-21x + 70 = 25x + 50
On solving we get :-4x = 20
x = 5
on substituting x in (i) we get 15 and 25.A function is shown below.
f(x) = 8x - 11
What value of x makes f(x) = 21?
The correct value in this function is f(21) = 157
This question is related to substitution of values. To solve it, just: change x by the indicated value and thus calculate normally.
– The given function being f(x) = 8x - 11, replace X by 21:
f(x) = 8x - 11
f(21) = 8 . 21 - 11
– Finally, just calculate the expression now, like this, multiplying and subtracting the numbers:
f(21) = 8 . 21 - 11
f(21) = 168 - 11
f(21) = 157
Therefore, the correct value of this function will be f(21) = 157

A ladder 20 m long rests against a vertical wall so that the foot of the ladder is 9 m from the wall. a Find, correct to the nearest degree, the angle that the ladder makes with the wall. b Find, correct to 1 d.p., the height above the ground at which the upper end of the ladder touches the wall.
Answer:
(a) 27°
(b) 17.9m
Step-by-step explanation:
According to the attachment
⠀
let AB be the ladder
BC be the distance between the ladder and wall
⠀
(a) We have to find ∠A by trigonometry formula
[tex] \sf \sin A = \frac{perpendicular}{hypotenuse} [/tex]
Here angle A is facing BC so it is perpendicular
and AB is the longest side so it is hypotenuse
[tex] \sf \implies \sin A = \frac{BC}{AB} \\ \\ \\ \sf \implies \sin A = \frac{9}{20} \\ \\ \\ \sf \implies \sin A = 0.45 \\ \\ \\ \sf \implies \sin A = \sin27{ \degree} \\ \\ \\ \sf \purple {A = 27{ \degree}}[/tex]
(b)
AC is the distance from the upper end of the ladder to ground
we will find it by Pythagoras theorem
[tex] \sf {hypotenuse}^{2} = {perpendicular}^{2} + {base}^{2} \\ \\ \\ \sf \implies {AB}^{2} = {BC}^{2} + {AC}^{2} \\ \\ \\ \sf \implies {20}^{2} = {9}^{2} + {AC}^{2} \\ \\ \\ \sf \implies 400 = 81 + {AC}^{2} \\ \\ \\ \sf \implies 400 - 81 = {AC}^{2} \\ \\ \\ \sf \implies 319 = {AC}^{2} \\ \\ \\ \sf \implies \sqrt{319} = AC \\ \\ \\ \sf \blue{\implies 17.86 = AC}[/tex]

The graph of y = cos x is transformed to the graph below. Which statement
about the graph is not correct?
QA. There is no phase shift.
OB. The period is pi.
OC. The amplitude is 2.
O. D. The midline is y = 1.5.
EIN
5
Answer:
d)The midline is y=1.5
Step-by-step explanation:
Because you can see in the graph that the midline is 1. So only c is no correct.
The amplitude is measured between the midline and the pik(highest or lowest value) of the function. This case is 2. True
The period is the distance between “equivalent” points. pi in this case. True.
The phase shift occur when the function is shifted on the x-axis. There is no phase shift. True.
If the number under the square root radical has no perfect souare
factors, then it cannot be simplified further.
TRUE
FALSE
Answer:
true
Step-by-step explanation:
Examples :
180 = 5 × 2² × 3²
Then
The number 180 has perfect square factors which are 2 and 3
Then
The number √180 can be simplified because:
[tex]\sqrt{180} =\sqrt{5\times 2^{2}\times 3^{2}}[/tex]
[tex]=\sqrt{5\times \left( 2\times 3\right)^{2} }[/tex]
[tex]=\sqrt{5\times \left( 6\right)^{2} }[/tex]
[tex]=\sqrt{5} \times \sqrt{6^{2}}[/tex]
[tex]=6\sqrt{5}[/tex]
On the other hand :
10 = 5 × 2
Then
The number 10 has no perfect square factors
Then
The number √10 cannot be simplified because:
[tex]\sqrt{10} =\sqrt{5\times 2} =\sqrt{5} \times \sqrt{2}[/tex]
[tex]\text{and} \ \sqrt{5} \times \sqrt{2} \ \text{is not a simplified expression of} \ \sqrt{10} \ \\\text{,in fact it is more complicated than} \ \sqrt{10}[/tex]
