Answer:

Step-by-step explanation:

45/35 = 27/x

9/7 = (3 * 9)/x

1/7 = 3/x

x = 21

P, Q & R form a right-angled triangle.

kvasek [131]

Answer:

∠RPQ = 27

Step-by-step explanation:

In ΔSRQ,

∠R = 90

∠SQR = 36°

∠R + ∠SQR + ∠RSQ = 180 {Angle sum property of triangle}

90 + 36 + ∠RSQ = 180

126 + ∠RSQ = 180

∠RSQ = 180 - 126

∠RSQ = 54°

∠PSQ +∠RSQ = 180 {Linear pair}

∠PSQ + 54 = 180

∠PSQ = 180 - 54

∠PSQ = 126

In ΔPSQ,

SQ = PS ,

So, ∠SQP = ∠SPQ {Angles opposite to equal sides are equal}

∠SQP = ∠SPQ =x

∠PSQ + x +x = 180 {Angle sum property of triangle}

126 + 2x = 180

2x = 180 - 126

2x = 54

x = 54/2

x = 27

∠RPQ = 27°

Find the approximate area between the curve f(x) = -4x² + 32x and on the x-axis on the interval [0,8] using 4 rectangles. Use th

Doss [256]

Split up the interval [0, 8] into 4 equally spaced subintervals:

[0, 2], [2, 4], [4, 6], [6, 8]

Take the right endpoints, which form the arithmetic sequence

$r_i=2+\dfrac{8-0}4(i-1)=2i$

where 1 ≤ <em>i</em> ≤ 4.

Find the values of the function at these endpoints:

$f(r_i)=-4{r_i}^2+32r_i=-16i^2+64i$

The area is given approximately by the Riemann sum,

$\displaystyle\int_0^8f(x)\,\mathrm dx\approx\sum_{i=1}^4f(r_i)\Delta x_i$

where $\Delta x_i=\frac{8-0}4=2$ ; so the area is approximately

$\displaystyle2\sum_{i=1}^4(-16i^2+64i)=-32\sum_{i=1}^4i^2+128\sum_{i=1}^4i=-32\cdot\frac{4\cdot5\cdot9}6+128\cdot\frac{4\cdot5}2=\boxed{320}$

where we use the formulas,

$\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2$

$\displaystyle\sum_{i=1}^ni^2=\frac{n(n+1)(2n+1)}6$

To win a prize at a fair you must throw a coin into a space that is 7.0 cm long and 4.0 cm wide. what is the area of the space y

dlinn [17]

Alright, lets get started.

space that is 7.0 cm long and 4.0 cm wide it means space is in rectangular shape.

The lenght of the space = 7 cm

The width of the shape = 4 cm

The formula of area of rectange = length * width

The area of rectange = $7*4$

The area of rectange = 28 square cm

So, the area of the space you are aiming for 28 square cm. : Answer

Hope it will help :)
